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.

Hello Roopal08!
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

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

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

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

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

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

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

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

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

you could add it to the tasks

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

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 rex@apertus.org in the meantime and I'll notify you.
18:59
anuditverma
ok, cool.
19:02
Bertl
is this your first GSoC time?
19:06

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?

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

19:33
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

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
