Hello supragya_ :)
16:50
supragya_
How's it going TofuLynx ?
16:51
TofuLynx
I am good! How about you?
16:51
supragya_
Quite good... how's your project?
16:53
TofuLynx
It's going well, implementing openCL and stuff, the kernels are done, so there isnt much to do left
16:53
supragya_
nice to know
16:53
TofuLynx
how about yours?
16:54
supragya_
well... finished documentation today... for the proof of concept "MLV recorder and publisher"
16:55
supragya_
so I guess a bit part is done.... let's see what else is to be added or removed
16:55
ArunM
hello everyone
16:55
TofuLynx
Cool! :P
16:55
TofuLynx
Hello ArunM !
16:55
supragya_
Hello ArunM
16:55
TofuLynx
I touched my documentation too, revamped the images, as they kinda sucked
16:55
TofuLynx
but now I'm satisfied with the new images
16:55

we'll have to see...
16:58
TofuLynx
Ok :P
16:59
nmdis1999
You've got plenty of time for that! :)
16:59
TofuLynx
why did you call it develuper?

OK. Meeting time.
17:00
nmdis1999
great!
17:00
nmdis1999
you'll be our host today @RexOrCine ?
17:00
TofuLynx
Okk :D
17:00
RexOrCine
Yeah, I'll be chairing the meeting today. This is unusual, but these are unusual circumstances. It's been said that se6astian has had an offer from L'Oreal so he's gone to have a sit down with their money men. That's all I know at the moment, can't even remember who said it so please don't ask hundreds of questions. But it's not about the desktop wallpaper - https://s33.postimg.cc/ewgmcvusf/apertus_Paris_Desktop.png ... so, exciting times.
17:01
TofuLynx
ooooooooooh
17:01
TofuLynx

17:01
nmdis1999
yaay!

17:01
RexOrCine
The shampoo people.
17:01
TofuLynx
finally I will fix my hair
17:01
supragya_
hair care brand with apertus?
17:02
RexOrCine
Well, they're interested in the camera, and Sebastian. let's say that.
17:02
ArunM
now we want goodies too
17:02
TofuLynx
;)
17:02
nmdis1999
haha..good xD
17:03
RexOrCine
nmdis1999: You wanna go first?
17:03
nmdis1999
Sure, would love to!
17:03
nmdis1999
Okay, So, this week I cleaned up codes, updated my github ran tests on all three tools (i.e histogram, waveform, and vectorscope).
17:03
nmdis1999
I have implemented the formula discussed with a1ex last week, here are the codes :
17:04
nmdis1999
https://github.com/nmdis1999/Histogram
17:04
nmdis1999
https://github.com/nmdis1999/Waveform
17:04
nmdis1999
https://github.com/nmdis1999/Vectorscope
17:04
nmdis1999
One can also test them on beta
17:04
nmdis1999
../opt/ITI/gsoc18
17:04
nmdis1999
After this, I bought my own domain and hosting server (for uploading my work) :)
17:04
nmdis1999
I have started working on the documentation (it still needs to be completed, hopefully will do within next 2 days! )
17:05
nmdis1999
One thing to note here is that even though I have tried to implement the features we initially wanted.
17:05
nmdis1999
I still think we can add a lot of better things and since itâd extend the deadline , so for now I tried to keep it short, but I am planning to talk to a1ex to continue working on these after gsoc, so that it could be useful for apertus and others in future, I am hoping for the best :)
17:05
nmdis1999
Here are some plot's I got after testing the three tools https://imgur.com/a/vxpd1b9

17:06
TofuLynx
You fixed that issue with big datas?
17:06
nmdis1999
the first one is for vectorscope, (this time it's calculating and plotting R/G and B/G data)
17:07
nmdis1999
TofuLynx, that's something of a problem which I tried finding (I am not sure if it's code fault because the text file so generated has all the data )
17:07
nmdis1999
the problem occurs while plotting
17:07
nmdis1999
so, a1ex's approach was to first focus on the result we are getting and improve it
17:07
TofuLynx
Okk :)
17:07
supragya_
maybe the plot points are too many
17:07
alexML
these histograms look like random noise ;)
17:07
nmdis1999
probably
17:08
nmdis1999
alexML : the histogram for histogram.c is is showcased here nmdis1999.com/wp
17:09
nmdis1999
I tried not using black and white level because 1. we still aren't sure if they'd be okay 2. the data I am using is in range 0-255 (I think we talked about directly implementing the logarithmic formula on raw data, right?)
17:10
nmdis1999
ftp://ftp.apertus.org/AXIOM-Beta/iti/raw-exposure.html <- a1ex wrote this document for information regarding the task :)
17:10
alexML
that might be the issue: raw12 data is definitely not 0-255
17:10
Bertl
only at very low exposures :)
17:11
alexML
supragya_: I'm unable to reply in the chat window, I get some messages from a robot that tells me Bertl should fix something :P
17:11
nmdis1999
while I output buffer data (on which we'd work) it gives lesser values (I am not sure if it's exceeding white balance )
17:11
supragya_
it's 0 to 2^12...
17:12
supragya_
if variables are not correct, they may not complain and provide lsb maybe>
17:12
supragya_
try scaling down
17:12
Bertl
alexML: huh? which chat window?
17:12
supragya_
DM
17:12
supragya_
any idea btw... alexML ?
17:14
alexML
nmdis1999: with IT8-chart-5ms.raw12, data range is from 0 to 2853
17:14
supragya_
variables are not correct -> datatypes
17:14
nmdis1999
Okay! Thanks alexML :)
17:15
alexML
and its histogram definitely doesn't look like random noise

alexML
if you mix together all 4 channels (like you did in your code), you should get this: ftp://ftp.apertus.org/AXIOM-Beta/iti/IT8-chart-5ms.png
17:17
nmdis1999
alright, I am unable to understand why it's plotting it that way. I'll send you the code?

OK. Connection probs by the look of it.
17:21
g3gg0
cant chat either
17:21
supragya_
try webchat.freenode.net
17:22
TofuLynx
weird
17:22
nmdis1999
Okay, is it something or irc client's fault?
17:22

Is that you done nmdis1999?

Yes, I'll discuss plotting problems later with alex.
17:23

same here
17:23
Bertl
you need to identify with NickServ to PM anybody on freenode
17:23
g3gg0
ok, thats new
17:23
RexOrCine
104.
17:23
alexML
PM works after reconnecting
17:23
RexOrCine
TofuLynx: Your turn.
17:23
TofuLynx
Okk :)
17:24
TofuLynx
So, I had to finish the debayering kernels and implement a baseOCL class for opencine,
17:25
TofuLynx
I finished the kernels and did working versions of the baseOCL class, however, we (me and my mentor) didn't accept it, as it could be more structured and avoid classes that arent autonomous
17:26
TofuLynx
So, we are still working on the baseOCL class
17:26
TofuLynx
and also we have to handle the processors required.
17:26
TofuLynx
In other hand, I revamped the images of the documentation
17:26
TofuLynx
which previously werent good and were confusing
17:27
TofuLynx
https://wiki.apertus.org/index.php/OpenCine.Nearest_Neighbor_and_Bilinear_Interpolation
17:27
TofuLynx
https://wiki.apertus.org/index.php/OpenCine.Green_Edge_Directed_Interpolation
17:27
TofuLynx
And I am very satisfied with the new images :)
17:28
TofuLynx
So, that's all :D
17:28
RexOrCine
Good stuff. supragya_
17:29
supragya_
Hi
17:29
g3gg0
hi
17:29
supragya_
So the proof of concept system for MLV containerization is over to a great extent
17:29
supragya_
and available with docs...
17:30
supragya_
I added a link earlier too... http://supragyaraj.com/dev/gsoc-2018/
17:30
supragya_
I have worked on adding cam2dng system and mlv2dng in single repo and separate it so as difference is clear
17:31
supragya_
support bash scripts are added for emulation to see how the containerization would function - both in camera, in transit, making cache, making mlv and finally DNG
17:32
supragya_
all of this is implemented and available for scruitiny...that's all
17:33
RexOrCine
OK Are there any other GSoC students present?
17:34
RexOrCine
Bertl: Do you have anything for us?
17:34
Bertl
well, not too much ...
17:35
Bertl
the new power board is progressing quite well
17:35
ArunM
Can i
17:35
ArunM
?
17:35
Bertl
sure, go ahead
17:37
ArunM
Should i start Rex0rCine
17:37
RexOrCine
Yes please.
17:37
ArunM
Integeration with original beta firmware is almost complete apart from testing the binaries on real Beta ;-)
17:37
ArunM
"I am a little behind schedule" can be said now
17:37
ArunM
but things are now going in a straight line
17:38
ArunM
During Integeration
17:38
ArunM
Placed lfsr for generating random data in place of pattern Generator,
17:38
ArunM
Changed delays to comply with the beta 250 MHZ clock etc and few minor changes to make the code work on zynq 7020
17:38
ArunM
nothing major to report there
17:38
ArunM
Last week went in optimisation of the integrated design, trying to fit it in fpga
17:39
ArunM
the design is synthesized and simulated without errors
17:39
ArunM
but still no binary file because of sparse resources left on fpga
17:39
ArunM
i now realised after talking with my mentor that Vivado was placing all the memory elements on LUTs instead of block ram and
17:40
ArunM
and the script was not adding constrain file
17:40
ArunM
hopefully i'll be done with testing on Beta in a day or two
17:40
ArunM
thats all :)
17:41
RexOrCine
Good stuff. there should be someone else iirc.
17:42
Bertl
Mahesh doesn't seem to be around
17:42
Bertl
rahul__: ping?
17:42
RexOrCine
Do you wanna carry on Bertl?
17:42
Bertl
yea, I'll do in the meantime ...
17:43
Bertl
we spent some quality time on the AXIOM remote last week too
17:43
Bertl
and some testing of the new heat sink is going on as well
17:43
Bertl
I'm also working on more test systems (Half-Betas) for all kinds of tests
17:43
Bertl
(they should be completed soon)
17:44
Bertl
that's it from my side ...
17:44
nmdis1999
What is Half-Betas?
17:44
Bertl
basically a Beta which ends right before the sensor
17:45
nmdis1999
oh...alright interesting stuff :)
17:45
Bertl
hopefully with ArunM's work, this will be very useful not just for non-sensor related work
17:46
nmdis1999
Nice :)
17:47
Bertl
anything from your side RexOrCine?
17:48
nmdis1999
off for now, be back later :)
17:48
nmdis1999
Goodnight everyone!
17:48
RexOrCine
Thanks for attending everyone. Will close this week's meeting with an update from Youranus - We went to see the injection moulding progress last week. Really good stuff. Best shirts were worn. Some pictures went out on Twitter here - https://twitter.com/AXIOM_Community/status/1021882698875449345 Footage is presently being edited but it'll be a few days I think. Herbert is testing the new heat sink at the moment. Enclosure parts have successfully been
17:50
