| 04:05 | Roopal08 | My name is Roopal Nahar and I am an undergrad student at IIIT Hyderabad . I am interested in working on the project "OpenCine: Raw Image Debayering Methods" . I have previous experience in C++ and C. I have taken courses in Computer Vision, Digital Image Processing and Statistical Methods in AI.
|
| 04:06 | Roopal08 | I have also worked on a project where I implemented Efficient graph based image segmentation ( http://cs.brown.edu/~pff/papers/seg-ijcv.pdf) in C++ . I have also designed a parallel version of this algorithm as a part of my research thesis. I have even done various projects on image processing and vision as a part of my course projects.
|
| 04:06 | Roopal08 | Please let me know how to proceed for applying to the GSOC program for this project.

|
| 04:07 | Bertl | sounds good!
|
| 04:07 | Bertl | you best get in touch with alexML and/or BAndiT1983|away when they will be around later (it's quite early in the morning in their timezone)
|
| 04:08 | Roopal08 | Okk Sure .
|
| 04:08 | Bertl | maybe check out a few IRC clients in the meantime and pick something you like
|
| 04:09 | Bertl | the web interface is good for occasional questions but it sucks for actual work

|
| 11:36 | Roopal08 | Sorry , I had classes in the morning .
|
| 11:37 | BAndiT1983 | ah, you were the one who were interested in de-bayering
|
| 11:37 | BAndiT1983 | have you read my response in the forum?
|
| 11:37 | d0 | Haha yeah had a date I nearly forgot : D
|
| 11:38 | BAndiT1983 | that could end bad ;)
|
| 11:38 | Roopal08 | nope . I didn't read the response . I will read them and get back to you .
|
| 11:39 | BAndiT1983 | no problem, usually you can find me here, i'm looking periodically at the chat
|
| 11:44 | Roopal08 | So , I have worked on various image processing algorithms on images and videos . I already had a look on opencine . And it looks quite interesting to work on .
|
| 11:45 | BAndiT1983 | try to build it, if you don't have linux, then you can use VirtualBox to get it running, that's how i'm testing if i don't want to reboot my machine
|
| 11:47 | BAndiT1983 | currently i'm preparing a VM for instant usage, without the need to set the environment up, package requirements are relative low at the moment, but not everyone wants to go all the way
|
| 11:47 | Roopal08 | I have linux .
|
| 11:47 | BAndiT1983 | even better

|
| 18:06 | Uttaran | Im interested in working with your organisation
|
| 18:06 | Bertl | sounds good! what are your specific interests?
|
| 18:07 | Uttaran | left the channel |
| 18:07 | Spirit532 | I guess none :P
|
| 18:08 | Bertl | let's attribute it to an IRC problem for now :)
|
| 18:09 | BAndiT1983 | hoy do you see if it is webinterface? as you told it one guy before
|
| 18:09 | BAndiT1983 | *how
|
| 18:09 | Bertl | when the connect message is from *@gateway/web/freenode/ip.*
|
| 18:09 | Bertl | then it is the freenode web interface
|
| 18:10 | BAndiT1983 | ah, thanks, didn't knew
|
| 18:11 | Bertl | np
|
| 18:11 | Uttaran | joined the channel |
| 18:11 | Uttaran | Join
|
| 18:11 | Bertl | wb Uttaran!
|
| 18:12 | Uttaran | Sorry my net connection just went down, had to log in again
|
| 18:12 | BAndiT1983 | no problem
|
| 18:12 | Bertl | did you get the last question?
|
| 18:12 | BAndiT1983 | Bertl, by the way, is ioctl available in Arch?
|
| 18:12 | Uttaran | Yeah
|
| 18:13 | Uttaran | Got last question
|
| 18:13 | Bertl | BAndiT1983: hmm?
|
| 18:13 | BAndiT1983 | http://elinux.org/Interfacing_with_I2C_Devices
|
| 18:13 | BAndiT1983 | just preparing, but will write basic daemon on Mint in VM for now, because debugging QEMU could be hell, which i would like to avoid today :D
|
| 18:14 | Bertl | yes, Arch is a 'normal' distro like you would put on your desktop
|
| 18:14 | BAndiT1983 | alright, so possibly we need some lib in-between, but i will investigate that of course
|
| 18:14 | Bertl | the ARM flavor doesn't feature x86 specific stuff, but that's about all the difference
|
| 18:15 | BAndiT1983 | Uttaran, are you there? What are your interests?
|
| 18:15 | BAndiT1983 | this question was what Bertl meant
|
| 18:15 | Uttaran | Im interested in working with c, c++, fpga
|
| 18:15 | Bertl | great! do you have FPGA experience?
|
| 18:15 | Uttaran | That is relevant to your project
|
| 18:16 | Uttaran | Sadly no, I am learning
|
| 18:16 | Uttaran | Amateur
|
| 18:16 | Bertl | well, don't worry, there are also very simple tasks which need to be done
|
| 18:17 | Uttaran | Im ready to put in all my efforts
|
| 18:17 | RexOrCine | Uttaran - have a look here: https://wiki.apertus.org/index.php/GSoC_Overview
|
| 18:17 | Uttaran | Sure
|
| 18:18 | Bertl | let me know if there are specific tasks you are interested in ...
|
| 18:19 | Uttaran | Ok

| 18:22 | Spirit532 | Looking at OpenCine - I've got LibTIFF code that exports fully compatible and correct DNGs easily, without needing the absolutely horrific Adobe SDK
|
| 18:23 | Spirit532 | Just modified Elphel code.
|
| 18:23 | Uttaran | Join
|
| 18:23 | Bertl | Spirit532: excellent! please contribute
|
| 18:23 | Spirit532 | No idea where D:
|
| 18:23 | Spirit532 | I've just got the code, part of another project.
|
| 18:23 | Bertl | Uttaran: you are automatically joined by the web UI, no need to explicitely issue a /join command or similar
|
| 18:24 | Bertl | Spirit532: probably the easiest way is to have a chat with BAndiT1983
|
| 18:24 | BAndiT1983 | i'm here, just thinking
|
| 18:25 | Uttaran | No my net connection is going down at times and so I have to log in again and again :(
|
| 18:26 | Uttaran | Sorry for that
|
| 18:26 | Bertl | no problem
|
| 18:27 | BAndiT1983 | Spirit532, where should it be used? For which part, i mean.
|
| 18:27 | BAndiT1983 | 123
|
| 18:28 | Spirit532 | DNG export
|
| 18:28 | Spirit532 | feed it data, writes the tags & such
|
| 18:28 | Spirit532 | just using LibTIFF instead of Adobe SDK, just like the Elphel cameras do.
|
| 18:29 | BAndiT1983 | haven't thought of Adobe SDK at all, as it all should stay open-source
|
| 18:29 | Spirit532 | it's open-source alright
|
| 18:29 | Spirit532 | just sucks and a huge pain to implement.
|
| 18:30 | Bertl | okay, I think that is going the wrong way
|
| 18:30 | Bertl | maybe just wrap your modifications up or put them in a repository
|
| 18:31 | Bertl | then link it on the wiki or send it to me via eMail
|
| 18:31 | Bertl | some documentation would be appreciated as well
|
| 18:32 | BAndiT1983 | just said in pm, to put in lab for example
|
| 18:32 | Spirit532 | got a link?
|
| 18:33 | BAndiT1983 | lab.apertus.org
|
| 18:33 | BAndiT1983 | just create a task in OC section there
|
| 18:34 | BAndiT1983 | Bertl, do you know if se6astian will join later again?
|
| 18:35 | Spirit532 | I'll PM you the chunk of commented code, you figure out where you want it best.
|
| 18:36 | Bertl | I'm pretty sure he will
|
| 18:36 | BAndiT1983 | why are people avoid lab? :D it's not that hard to use
|
| 18:37 | Spirit532 | I'm not registered
|
| 18:39 | BAndiT1983 | done -> https://lab.apertus.org/T759
|
| 18:46 | BAndiT1983 | have uploaded your example and attached it to the task
|
| 18:46 | Bertl | excellent, tx!
|
| 18:46 | BAndiT1983 | you should really register there, i use my github login, so i don't need new account
|
| 18:47 | BAndiT1983 | Bertl, do you use Xilinx tools in Linux?
|
| 18:50 | Bertl | yup
|
| 18:50 | RexOrCine | What stage are we at with recording data at the moment? ie. How is the Beta recording? External HDMI still?
|
| 18:50 | anuditverma | joined the channel |
| 18:50 | BAndiT1983 | how stable are they, as Windows versions are lousy
|
| 18:50 | Bertl | RexOrCine: yup
|
| 18:51 | Bertl | BAndiT1983: no stability problem here
|
| 18:51 | RexOrCine | Are you able to foresee a timescale for SD card?
|
| 18:51 | BAndiT1983 | alright, then i will try them in linux, it freezes in windows when file dialog is opened
|
| 18:51 | Bertl | but also note, that I do not use the GUI for much
|
| 18:51 | Bertl | RexOrCine: nope
|
| 18:52 | RexOrCine | Cheers.
|
| 18:53 | Uttaran_ | joined the channel |
| 18:53 | Bertl | we have prototype hardware for an SD card plugin, but we had no time to start testing with it yet
|
| 18:54 | Bertl | I don't think it made it into the GSoC projects either
|
| 18:55 | Bertl | but at least in theroy, we could add it there if somebody takes the time to whip up a task description
|
| 18:55 | Uttaran_ | left the channel |
| 18:55 | BAndiT1983 | you could add it to the tasks
|
| 18:55 | anuditverma | Hi, I am Anudit Verma, GSoC'17 aspirant, sorry to interrupt in between, I just want to know, is there any separate mailing list for GSoC students-updates ? couldn't find on the mailing lists' page, TIA
|
| 18:55 | Uttaran_ | joined the channel |
| 18:55 | Bertl | Hello Anudit!
|
| 18:56 | Bertl | no special ML yet, AFAIK, but maybe a good idea to create one
|
| 18:56 | Bertl | please check with RexOrCine and/or se6astian|away
|
| 18:57 | anuditverma | okay @Bertl, thanks a lot
|
| 18:57 | RexOrCine | I'll action it anuditverma - if you mail me at *email address removed* in the meantime and I'll notify you.
|
| 18:59 | anuditverma | ok, cool.
|
| 19:02 | Bertl | is this your first GSoC time?
|
| 19:06 | anuditverma | Nope, I have been a GSoC student once with CiviCRM
|
| 19:08 | Bertl | thought so ..
|
| 19:08 | Uttaran | left the channel |
| 19:13 | anuditverma | I have been following the AXIOM team talks videos for a while now, exciting stuff ! really intriguing to know about how all the tech works.
|
| 19:13 | Bertl | and now you are ready to dive in and experience it all hands-on, yes? :)
|
| 19:14 | anuditverma | Yeah ! absolutely, looking forward to it :)
|
| 19:15 | Bertl | sounds good! any special interests?
|
| 19:16 | illwieckz | left the channel |
| 19:20 | anuditverma | FYI, when I was in school, I joined a photography club for one summer, got the idea about how camera works and tech behind it, it was fascinating too, so yeah it does interest to me now, and it does have a bit of nostalgic touch I would say and it's like all coming back.
|
| 19:23 | Bertl | did you have a look through the prepared tasks yet?
|
| 19:29 | anuditverma | Had a conversation with @maltefiala, said they will update the task as soon as they have improved the onboarding process
|
| 19:29 | BAndiT1983 | maltefiala already added according tasks, as some things have to be prepared
|
| 19:30 | BAndiT1983 | i will add a main daemon, as you seem to have linux experience, according to your website, you could take a look anytime later if improvements or fixes have to be made
|
| 19:31 | BAndiT1983 | Bertl is responsible for hardware and is the source for info on that
|
| 19:32 | se6astian|away | changed nick to: se6astian
|
| 19:32 | BAndiT1983 | ah, se6astian is here
|
| 19:32 | anuditverma | okay @BAndiT1983, I will look into the tasks now
|
| 19:33 | BAndiT1983 | se6astian, you haven't replied about MLV support in OC yet ;)
|
| 19:34 | se6astian | back
|
| 19:34 | BAndiT1983 | wb
|
| 19:35 | se6astian | ad MLV support, what formats do you support already, which others are planned?
|
| 19:35 | BAndiT1983 | i can show MOV preview, and load (C)DNG files
|
| 19:35 | BAndiT1983 | it was just about to expand to the ML community, could be helpful
|
| 19:37 | se6astian | agreed, those folks could get interested in helping with dev then
|
| 19:39 | se6astian | but how much extra effort do you estimate it?
|
| 19:39 | BAndiT1983 | i cann anytime expand by using already established lib, but OC was meant to be for special formats, as many programs use libraw or similar for photos
|
| 19:39 | BAndiT1983 | i will take a look first, before i can estimate
|
| 19:40 | se6astian | changed nick to: se6astian|away
|
| 19:40 | BAndiT1983 | don't know if i should use FFMPEG or custom loader for it, depends on required features, like 10/12 bit, which i've seen was request recently in ML forum

| 19:42 | RexOrCine | anuditverna - If there's anything besides a mailing list which you think would improve our GSoC procedures would you let us know?
|
| 19:43 | anuditverma | Okay, surely I will if something comes up
|
| 19:46 | anuditverma | I have a small question though, on the ideas' page, some of them are mentioned under backlog, what's backlog and are these ideas confirmed ? or they need improvements ?
|
| 19:47 | Bertl | that is just the 'default' name for phabricator workboard categorieso
|
| 19:47 | Bertl | i.e. means we have not assigned them to a specific category yet
|
| 19:47 | anuditverma | ok I see now, thanks for clarifying.
|
| 19:49 | Bertl | np, you're welcome!
|
| 19:55 | se6astian | anuditverma: mailing list set up
|
| 19:56 | se6astian | and invitation sent
|
| 19:56 | se6astian | anyone else here interested in being added now that I am at it: apertus° GSoC mailing list?
|
| 19:57 | anuditverma | So I am interested in Web-based AXIOM Beta API idea, I can see the last edit was made by @se6astian, I am able to see some of the examples for changing parameters on the camera internal command line, so those are the prepared tasks I need to perform ? I have gone through the links though, please let me know if I have to complete a work or a task.
|
| 19:58 | se6astian | also updated https://www.apertus.org/mailinglists
|
| 19:58 | anuditverma | thanks se6astian, I joined it.
|
| 19:59 | se6astian | anuditverma: great, we have disscussed this task internally today and streamlined the goals and approaches a bit
|
| 19:59 | se6astian | the history of this task is that the code was originally created for the axiom alpha
|
| 20:00 | se6astian | then ported to the axiom beta but just tuned so it would work basically
|
| 20:00 | se6astian | now it would be the right time to redesign it from scratch properly
|
| 20:01 | se6astian | the result of this discussion was this new task: https://lab.apertus.org/T757
|
| 20:01 | se6astian | which needs to be a bit more documented I think
|
| 20:01 | anuditverma | okay, I am following it
|
| 20:01 | se6astian | but this discussion was just a few hours a go...
|
| 20:02 | se6astian | but as I understand it the idea is to create one central control deamon inside the camera
|
| 20:02 | se6astian | that gets/sets all camera parameters
|
| 20:02 | se6astian | as central API
|
| 20:03 | Uttaran_ | left the channel |
| 20:11 | BAndiT1983 | right, i'm on it, investigating at the moment
|
| 20:14 | anuditverma | So, we need something like a new separate control deamon, so it would not interfere with the other services so as to prevent the deadlock ? Correct me if I got this wrong. And this "user-space" is referred to a memory on the board ?
|
| 20:15 | BAndiT1983 | yes
|
| 20:16 | anuditverma | okay
|
| 20:16 | BAndiT1983 | daemon should handle the calls,like writing/reading from memory, to avoid dead lock
|
| 20:16 | Bertl | anuditverma: user-space is stuff runing without kernel priviledges on the ARM cores
|
| 20:17 | anuditverma | ah okay
|
| 20:17 | anuditverma | it makes sense now
|
| 20:18 | BAndiT1983 | still have to check ethernet on QEMU to have some virtual camera replica, so i can test the daemon per remote
|
| 20:20 | se6astian | anuditverma: could you help us clarify the task description so it fulfils GSoC requirements?
|
| 20:26 | anuditverma | actually I thought some tasks would be given to interested students for a particular idea to check their proficiency, but the "task description" term used by Phabricator is bit ambiguous and can be taken for actual tasks that are need to be performed. If not mentioned otherwise I guess
|
| 20:27 | BAndiT1983 | yes, the system does not explicitly tells you if the task is a bug, task or just discussion
|
| 20:27 | BAndiT1983 | i miss the categorization a bit, as i use jira at work
|
| 20:28 | anuditverma | I am familiar with jira too
|
| 20:29 | anuditverma | yes it does show/categorises the bugs/issues etc
|
| 20:31 | BAndiT1983 | i mean, that phabricator has no categories, one could organize it in different columns, but it's not sufficient, as columns are required for different parts of module development
|
| 20:31 | BAndiT1983 | at least labels would be nice
|
| 20:32 | Bertl | you realize that you can put tasks in more than one project?
|
| 20:33 | BAndiT1983 | newer one has tags, but i haven't seen it in our version
|
| 20:33 | anuditverma | could you please let me know at what usual timings I can see most of the apertus dev active on IRC ? I usually hangout late in nights here at my end or may be sometimes in the day time, whenever I get time.
|
| 20:33 | BAndiT1983 | yes i do, it's not my first bug tracker i use, there were jira, phabricator, quality center, bugzilla etc.
|
| 20:34 | Bertl | so you can use that as categories if you like
|
| 20:34 | Bertl | anuditverma: that is a tough one
|
| 20:34 | BAndiT1983 | then i would require something like OC ideas, OC bugs etc. projects
|
| 20:34 | BAndiT1983 | especially for Bertl :D
|
| 20:34 | anuditverma | haha sorry my bad
|
| 20:35 | Bertl | in general, most folks are around in the european evening
|
| 20:37 | anuditverma | so its about I guess 8 to 9 pm there ? this time
|
| 20:38 | Bertl | currently 9:40 pm here now
|
| 20:39 | Bertl | some folks like se6astian are heading to bed in an hour or two

| 20:39 | anuditverma | okay, I somewhat got the idea when I should come here
|
| 20:39 | Bertl | others like me usually spend the night around
|
| 20:39 | Bertl | but as there are folks from all over the world, it really depends on who is here
|
| 20:40 | BAndiT1983 | BETZ -> bertls engineer time zone :D
|
| 20:40 | anuditverma | lol
|
| 20:41 | Bertl | nah, actually it is BUT
|
| 20:41 | Bertl | Bertl's Unique Timezone
|
| 20:41 | se6astian | of course!
|
| 20:41 | Bertl | where it is always morning when I wake up, and night when I go to bed :)
|
| 20:42 | se6astian | I was explaining it as BOT bertls own timezone today... all wrong :)
|
| 20:43 | BAndiT1983 | was already wondering if you are somewhere else at the moment, until se6astian told us what's the thing
|
| 20:48 | anuditverma | well fsfe does explains the european timings
|
| 20:57 | anuditverma | alright I also going to bed now, it's 2:24 am here, got up early today for an exam, finally it was the last one :D Please let me know about the tasks/work about the web AXIOM beta API project , I will follow the mailing list & Phabricator for updates, I'll catch up later, thanks for the help and for clearing my doubts :)
|
| 20:58 | BAndiT1983 | i think maltefiala wanted to prepare something, as we agreed that i deliver de daemon and then there will be several adapters for different languages or protocols
|
| 20:58 | BAndiT1983 | like JSON, XML, C, Go etc.
|
| 20:58 | Bertl | anuditverma: you're welcome! have a good night!
