se6astian
welcome to another weekly team/gsoc meeting
17:01
se6astian
ymc98_2 told us earlier to be sick and not able to attend today
17:01
se6astian
anyone else who wants to report/share again please PM me now and I will put people in order
17:02
se6astian
nmdis199-: you are first, please go ahead
17:02
nmdis199-
Awesome :)
17:03
nmdis199-
Last week was pretty good, after talking to sebastian on irc I did wrote a code for calculating luminance and it showed result however, since I didn’t know what data was being provided by dev/mem I couldn’t have verified it.
17:03
nmdis199-
The code is present in ../opt/ITI/Waveform on beta.
17:03
rahul_
hello!
17:03
nmdis199-
So Bertl suggested me to verify the code by writing an image into the memory, so I proceeded toward it and wrote the code to write an image into memory and calculate luminance.
17:03
nmdis199-
Now, this was the point where my code on running on beta showed Segmentation fault.
17:03
nmdis199-
We did some gdb testing but came to conclusion that it was weird to write into framebuffer first and the read data back.
17:04
nmdis199-
Therefore, mid-week Bertl asked me to write modified version of mimg (which is in processing tools) and explained me what it does and how.
17:04
nmdis199-
I started working on it and we named it load_raw the code can be seen here -> https://github.com/nmdis1999/load_raw
17:04
nmdis199-
it is also uploaded on the beta
17:04
nmdis199-
Also, it was tested and didn’t failed us on beta :) we still need to test it with a raw file though.
17:04
nmdis199-
This can be useful for future purposes as well as on my waveform tool for writing an image to the memory which is a much better way.
17:05
nmdis199-
Now, I’ll make modified snap version to dump the image.
17:05
nmdis199-
that's all :)
17:05
se6astian
great, so with load_raw we should already be able to draw HDMI overlays currently?
17:06
nmdis199-
load_raw only deals with raw image, because it wasn't wise to use register
17:06
Bertl
no, the tool is to load a full raw image into the framebuffer
17:06
Bertl
bascially the counterpart to cmv_snap3
17:06
nmdis199-
yes :)
17:07
se6astian
ah, so you fill the framebuffer instead of reading it out
17:07
nmdis199-
yes, we are trying to write into memory and then use modified (cmv_snap3) to dump it
17:07
se6astian
and the idea is to write the histogram data into the framebuffer so cmv_snap can read it and save it into an image correct?
17:08
nmdis199-
yes, we can use it for histogram as well as waveform tool
17:08
Bertl
the main idea is to be able to run the various tools (waveform, histogram, etc) on 'known' good test data (raw images)
17:09
nmdis199-
precisely :)
17:09
se6astian
great, many thanks for reporting!
17:09
se6astian
anything more to add?
17:09
se6astian
otherwise TofuLynx is up next
17:10
nmdis199-
Not much for right now, I will be probably working on modified cmv_snap3 from today onwards :)
17:10
TofuLynx
Ok :)
17:10
TofuLynx
Can I start reporting nmdis199-?
17:10
nmdis199-
yes, sure go on :)
17:11
TofuLynx
Ok! So, last week, I didn't do much things. It was mainly documentating the code and cleaning up some bits.
17:12
TofuLynx
https://docs.google.com/document/d/18o9ajnAF1_DEy2CfYi_jYxDmurW-KEtojqL3_c3SPBU/edit?usp=sharing
17:12
TofuLynx
I am writing the documentation here so that I can later port it to the apertus wiki
17:13
TofuLynx
So far, the only thing I have to finish is the SHOODAK2 documentation. The documentation helped me notice some areas of the code that I can optimize
17:13
TofuLynx
This is essential to prepare myself to the next task, which is to accelerate the algorithms with openMP
17:14
TofuLynx
By the way, I didn't do so much last week because I was occupied with my last university exam
17:14
TofuLynx
so now I am, hopeful, free and fully dedicated to apertus :D
17:15
se6astian
may I suggest to add some example debayered images in the documentation
17:15
TofuLynx
Yeah, I have to add some examples
17:15
TofuLynx
Thanks for the suggestion!
17:16
se6astian
many thanks for the report!
17:16
TofuLynx

17:16
se6astian
rahul_ you are up next
17:17

17:18
rahul_
hello
17:18
rahul_
I have made the required ‘focus peaking kernel’ as reported in the last meeting,
17:18
se6astian
url says "Pastebin deleted"
17:18
rahul_
This time I ran functional and timing tests so as to ensure the proper functioning of the module.
17:18
TofuLynx
the link for me says pastebin deleted, rahul_
17:18
rahul_
In the coming week I will be done with my university exams and will try to incorporate my design into the existing Pipeline.
17:18
BogdanXOR

17:19
rahul_
ya the link was deleted
17:19
rahul_
this is all from my side
17:20
se6astian
rahul_ do you have a way to simulate the focus peaking kernel output with a provided input image?
17:21
rahul_
currently, I've done it with pixel values so as to check how my system buffers and produces the required pixel values.
17:22
rahul_
I dont have a way to simulate.
17:22
rahul_
until I implement it on actual hardware
17:23
Bertl
simulation would be possible but rather tricky
17:23
se6astian
right so the plan is to evaluate the HDMI output on the remote beta I assume?
17:23
rahul_
yes
17:23
se6astian
great
17:23
se6astian
I upgraded the remote beta webcam
17:23
se6astian
https://wiki.apertus.org/index.php/AXIOM_Beta_Remote_Access
17:24
Bertl
as the design is for the output pipeline, it would also be possible to test it with uploaded raw images on the Beta
17:24
se6astian
images should be much better now
17:25
rahul_
ok, once I finish the incorporation of my design in the pipeline, I will start testing it on beta
17:25
se6astian
even with uploaded raw images it would require looking at the LCD output via webcam right?
17:26
rahul_
I think so
17:26
Bertl
depends on how it gets implemented
17:26
Bertl
it would be possible to store the peaking output into memory as well
17:26
se6astian
rahul_ if the webcam view turns out to be non optimal or you need the LCD moved to get a better look contact RexOrCine (here on irc) as he is in the office almost daily and can move stuff around
17:26
Bertl
(but we'll see what we can do once we get there :)
17:27
se6astian
right
17:27
rahul_
sure
17:27
se6astian
many thanks for the report!
17:27
se6astian
supragya is up next
17:27
supragya
Good evening everyone
17:28
supragya
so, the last week, I added linearization table into already existing MLVFS
17:28
supragya
some cleanup and rectification still needs to be done
17:28
supragya
however, from mlv, dngs are coming out fine with linearization table effecting the colors
17:29
supragya
I am currently working on merging the previous cam2mlv system with this modified mlvfs to create a final dng out of actual raw12
17:30
supragya
then, I will look into new blocks in mlv that needs to be added for our use and implement it
17:30
supragya
that's all till now
17:31
supragya
(I updated the status to the mentors using the email... last friday if I am not wrong)
17:31
se6astian
great, thanks!
17:31
se6astian
any images I can share via social media about this?
17:32
supragya
there was a test image... a burnt out magenta render of a mlv...
17:32
se6astian
also from any other students: rahul_ TofuLynx nmdis199- ?
17:32
supragya
although that was a test image
17:32
supragya
so I am not sure if that serves the purpose
17:33
nmdis199-
I was planning to write a blog about working with apertus (so if you want I can provide day in a day or two)
17:33
se6astian
that would be great!
17:33
se6astian
but even just single images or short videos with a bit of context what we are seeing would be great
17:33
nmdis199-
Okay, then will do upload a blog (preferably on medium) :)
17:34
TofuLynx
Well you can upload a comparison from the 3 algorithms from my part
17:34
nmdis199-
supragya, you did made a video right? Is it working the Qt one ?
17:34
supragya
https://www23.zippyshare.com/v/jETeM1Lr/file.html - this was linearization using random values
17:34
supragya
these (above) are the images...
17:35
illwieckz
joined the channel
17:35
supragya
the linearization table was synthetic... but modifies MLVFS for us...
17:35
se6astian
thanks
17:35
supragya
nmdis199-: not sure what you are asking me...
17:35
TofuLynx
Do you want the comparison, se6astian ?
17:36
nmdis199-
The video for building up OpenCine (the one which I tried making on my ubutnu :P )
17:36
supragya
yes... made that
17:36
se6astian
its in here now: https://www.apertus.org/opencine
17:36
se6astian
and the wiki
17:36
se6astian
TofuLynx: yes please
17:36
TofuLynx
Ok. Please wait a moment
17:37
TofuLynx
Do you have any preferred image?

17:37
TofuLynx
Ok! :)
17:38
nmdis199-
se6astian ,I'll email the blog you then, I don't have much images right now (because we haven't plotted waveform tool yet) so will that do?
17:39
rton
joined the channel
17:39
se6astian
the image situation should soon change when you can write and read images to/from memory
17:39
se6astian
blog post is also great
17:39
nmdis199-
yes it should be :) will do
17:39
se6astian
ok, if there are no further topics I will give a brief update
17:40
nmdis199-
sure!
17:40
se6astian
max emailed me the first draft edit of the next team talk episode
17:40
se6astian
so that is progressing
17:40
se6astian
I attended a cooperative forming workshop as we plan to create an apertus or AXIOM cooperative as legal commerical entity
17:42
se6astian
we secretely updated our brochure: https://apertus.org/AXIOM_Beta_Brochure_02.04.pdf
17:43
se6astian
lots of wiki clean ups and restucturing going on: https://wiki.apertus.org/index.php?title=Special:RecentChanges&limit=250&days=14
17:43
se6astian
work on finishing the compact enclosure is also slowly progressing
17:44
se6astian
also started software development with my limited time on the actual first AXIOM Remote prototype hardware today
17:44
Bertl
finally we did some extensive testing on the laser cut enclosure which will also be quite helpful for the future Compact version of the Beta
17:45
Bertl
mostly in regard of thermal design and airflow
17:46
Bertl
the data should be available today or tomorrow
17:46
se6astian
felix_: is also making progress with the production hardware design of the SDI plugin module
17:47
se6astian
thats it from my side!

17:48
se6astian
bye!
17:48
supragya
same... with me..
17:49
Bertl
rahul_: one way to test your blocks easily would be to wrap them in a simple HLS design
17:49
supragya
btw... felt great hearing progress about the org... se6astian
17:49
Bertl
reading the data from DDR and writing the resulting image back into DDR
17:52

haven't written this here yet: since i have some space left on the edge of the sdi module, i'll add a legacy synchronization input to the board; apparently that's something that is still used in production today
23:10
felix_
it's an adiitional hdbnc connector and maybe 10 euro in other parts, but it doesn't have to be populated. but yeah, compared to the sdi chips and the fpga that's not that much more... ;)

basically a LMH1981 with some passives and a connector
23:14

oh and fun fact: the version in the bigger package of the clocking chip i chose for the sdi board is also used in the new readout system for the atlas experiment at cern
