for those who didn't make it this year, we are still good on our promise to mentor you if you still want to work on those tasks ...
17:05
Bertl
they probably will check in over the next days, and probably read up on the irc logs

officially we are now in the community bonding period, but don't let that stop you from starting to work on the tasks ... IMHO it makes a lot of sense to start discussing details now, which will safe you a lot of time later

also note that we are all human (I think :) and thus we make errors (that's how we learn :) so do not hesitate to challenge and/or ask if something seems weird ...
17:22
TofuLynx
to challenge? xD
17:22
Bertl
well, do not take what 'we' (the mentors) say as granted
17:23
Bertl
it might be that we just explained something the wrong way or that we didn't even consider that it needs explanation (happens too often)

Kjetil
se6astian: cool
19:56
Bertl_oO
so do I understand that correctly there are 16-64 people sharing the same chip, but they get bonded differently to have two of each design/functionality?
20:06
se6astian
Shall I forward this question to them?

Kjetil
I'm really not sure. It's kindoff unclear how the bonding to external pins will work.
20:28
Bertl_oO
well, the only alternative is that everybody gets all the 16-64 features and each one only has about 1 or 2 pins/pads, which doesn't make too much sense to me :)
20:29
Kjetil
Unless there is some muxing/routing in the common fabric
20:29
Bertl_oO
yeah, they could cut connections/burn fuses once the chip is done

I guess all blocks will have to use the same I/O standard anyway, to avoid issues with ESD protection.

BAndiT1983: You there?
21:44
BAndiT1983
hi TofuLynx_
21:44
TofuLynx_
I don't see any glitches on my downscaler
21:45
BAndiT1983
looking at the moment through it, but first i have to move 12to16bit and 14to16bit methods o another place
21:45
TofuLynx_
Okk ;)
21:46
BAndiT1983
for faster processing there will also be 12to8bit, later 14to8bit if required
21:58
TofuLynx_
Andrejj
21:58
TofuLynx_
is there any documentation for the existing Bilinear Debayer?
21:59
BAndiT1983
not directly
21:59
BAndiT1983
what do you want to know?
22:00
TofuLynx_
it's very confusing to understand the methods such as BilinearFIlterRed()
22:00
BAndiT1983
you can refer to that -> http://www.dmi.unict.it/~battiato/mm1112/Parte%207.3%20%20-%20Demosaicing.pdf
22:00
BAndiT1983
have used very similar paper back then
22:00
BAndiT1983
let me check the method
22:01
BAndiT1983
it get the red pixels in vertical and horizontal positions, like a cross, to calculate missing one
22:01
BAndiT1983
don'T remember if it was done in diagonal way also or not
22:02
BAndiT1983
but seems like that, otherwise it wouldn't work
22:04
TofuLynx_
Ok! :)
22:04
TofuLynx_
also, the pdf you sent via the link is bugged for me
22:04
BAndiT1983
how so?
22:04
TofuLynx_
some overlapping texts and images
22:05
BAndiT1983
have no problem so far
22:05
BAndiT1983
which viewer do you use?
22:05
TofuLynx_
Chrome
22:05
TofuLynx_
Chromium*
22:06
BAndiT1983
hm, opera shows everything without a problem
22:06
BAndiT1983
try this one maybe, a bit more complex, but still useful -> https://hal.archives-ouvertes.fr/hal-00683233/document
22:06
BAndiT1983
page 15
22:07
TofuLynx_
Man, this is strange
22:07
TofuLynx_
every pdf is bugged
22:07
TofuLynx_
what happened to chromium? xD
22:10
BAndiT1983
good question, but opera and chrome use webkit, so it's rather strange

really strange
22:14
BAndiT1983
can you try to zoom in and out with ctrl+mouse wheel
22:14
BAndiT1983
?
22:14
TofuLynx_
yeah, it remains the same
22:14
se6astian
off to bed, good night

22:15
BAndiT1983
you can try to use dedicated 'PDF viewer
22:15
TofuLynx_
yeah
22:16
BAndiT1983
https://imgur.com/a/3ddN6c1
22:16
BAndiT1983
it looks like that in opera
22:16
TofuLynx_
with my system pdf viewer
22:16
TofuLynx_
it looks ok
22:16
TofuLynx_
Very strange
22:16
TofuLynx_
I will reboot my computer :)
22:16
BAndiT1983
some other thing occurs to me, maybe it's a problem with fonts
22:17
TofuLynx_
Wait, does pdf use fonts from the local PC?
22:17
BAndiT1983
if they are not embedded, then yes
22:17
TofuLynx_
I thought it stored the font in the pdf, as some kind of vectors
22:17
TofuLynx_
ah it's optional then?
22:18
BAndiT1983
think so
22:18
TofuLynx_
I will be right back :)

22:23
BAndiT1983
TofuLyn_, you can try to get more info in the pdf viewer, maybe there is some sort of metadata window and it would show missing fonts
22:27
TofuLyn_
but
22:27
TofuLyn_
if it is missing fonts
22:27
TofuLyn_
why is it missing in chromium and not in the system viewer ?
22:32
TofuLyn_
mozilla displays it correclty
22:32
TofuLyn_
correctly*
22:32
BAndiT1983
good question
22:33
BAndiT1983
depends on how the apps are substituting them
22:35
BAndiT1983
alright fixed a small bug, now the conversion methods are extracted to some general location for now, still needs restructuring later
22:35
BAndiT1983
TofuLyn_, have you tried to activate travis CI for your OC fork?
22:36
TofuLyn_
No, how do I do it?
22:37
TofuLyn_
also I need to learn how do I update the fork to match the original repo
22:37
BAndiT1983
you have to go to travis ci page and login with your github account
22:38
BAndiT1983
https://help.github.com/articles/syncing-a-fork/
22:38
BAndiT1983
github desktop seems to also have some things for that -> https://github.com/desktop/desktop/issues/1785
22:58
TofuLyn_
Ok! Synced!
22:59
TofuLyn_
I will probably grab the existing bilinear debayer and adapt it extensively as a base debayering class
23:00
BAndiT1983
don'T forget about new changes which will be uploaded soon, just have to figure the problem out, as the image is broken at the moment
23:00
TofuLyn_
what changes?
23:00
BAndiT1983
but conversion was moved out and some interface adjustments would also happen
23:01
BAndiT1983
adjustments to the base class of preprocessors for example
23:01
BAndiT1983
but still not detailed planning yet, have to get some free minute tomorrow to take a look at current pipeline, as i'Ve found some code parts which can be moved, consolidated or removed
23:02
TofuLyn_
Oh I see
23:03
TofuLyn_
in that case, I will just do some planning and documentation in order to implement the debayering classes
23:04
BAndiT1983
you can take a look at current state, maybe you will find also some stuff which can be moved to base class
23:05
BAndiT1983
such methods would be GetRed, GetGreen and GetBlue, maybe also some renaming
23:05
BAndiT1983
like GetRedChannel, so it's more clear
23:06
TofuLyn_
Yeah I prefer that way :P
23:06
BAndiT1983
?
23:07
BAndiT1983
ah, looks like base class already has virtual ones, but there is no point not to move them there
23:08
TofuLyn_
I meant that I agree with what you said :P
23:08
BAndiT1983
although interfaces should be pure virtual, usually, they still tend to pile up in bigger applications and as C++ allows to mix it, so my preference is to add stuff which doesn't change to them
23:10
TofuLyn_
what do you mean by "piling up"?
23:10
BAndiT1983
when developers implement a lot of interfaces, after some time there are quite a lot, a pile of them
23:11
BAndiT1983
so there should be some balance, also such things should be prevented -> https://en.wikipedia.org/wiki/Interface_bloat
23:16
TofuLyn_
so you try to avoid it by not doing changes to interfaces themselves?
23:16
BAndiT1983
it was meant a bit different
23:16
BAndiT1983
;)
23:17
BAndiT1983
for example C# or java are providing only pure interfaces, seen a lot of examples where the number of interfaces and abstract classes just exploded, sometimes because of just small changes new interfaces were implemented
23:18
BAndiT1983
C++ doesn't have an interface as such, so i cheat a bit and use soem hybrid approach, like adding simple method implementations to the "interface"
23:18
BAndiT1983
otherwise every class, which inherits from it, has to implement such small things over and over
23:19
BAndiT1983
or you create a base class in between, but then again it's an infinite vicious circle
23:19
BAndiT1983
there are a lot of approaches, so one has to find right balance, which depends on the project
23:23
BAndiT1983
so, off for today
