07:38
se6astian
I rendered a new banner image over night
07:38
se6astian
took almost 9 hours
07:38
se6astian
but its super smooth now
07:39
Bertl

07:41
se6astian
I will send an email right away
07:41
se6astian

07:47
Bertl

sasha_c
hey Bertl. How are you going?
08:00
Bertl
fine, fine, thanks for asking! and you?
08:01
sasha_c
Very well thanks! Waiting to hear back from Sebastian re: his views on the news article we're all waiting to publish.
08:01
Bertl
he just started his day, I expect feedback soon :)
08:01
sasha_c
Those were really nice images you guys captured :D
08:02
sasha_c
cool
08:03
se6astian
hi sasha
08:03
se6astian
just sent email
08:03
se6astian
and will look at the article next now
08:03
sasha_c
great, can't wait, as it's looking pretty nice imho
08:04
sasha_c
Let me know what your thoughts are re: the images that I've attempted to white balance and colour correct. I'm more than happy for you to correct the originals and re-upload
08:05
Bertl
se6astian: yup, looks indeed nice
08:05
Bertl
sasha_c: they look reasonably well for me, considering that we still have no proper profile
08:06
se6astian
very nice
08:06
se6astian
we should give them a bit of context though
08:06
sasha_c
Awesome, and yes, context is good :D
08:07
Bertl
yes, an interesting detail is that the fan (red) is turning at 1300 RPM
08:07
sasha_c
I take it you're referring to stating that one was taken under halogen lights and the other under natural lighting?
08:08
se6astian
I ll add a text draft
08:17
sasha_c
Great. Now I gotta go out and buy some food supplies before my local shops close. I'll be back in 30 minutes
08:23
se6astian
updated
08:24
Bertl
okay, definitely needs some line break/structure, it falls apart here at smaller widths
08:25
Bertl
i.e. when the third alpha2 image wraps
08:28
se6astian
fixed
08:28
Bertl
yep, looks good now
08:28
se6astian
latest elphel blog post: http://blog.elphel.com/2013/12/nc393-development-progress-the-initial-software/
08:29
Bertl
maybe change the '180deg connector for PMOD debug modules (on back)' to Two PMOD debug modules on the back
08:40
se6astian
done
08:49
Bertl
new lvds code works beautifully now ... will try to integrate it into the snapshot code tonight

guesst
se6astian: are there any details on exposure time/gain for those pics? seems noisy :)
10:15
guesst
(especially when they are downscaled pictures - or are they 1:1 crops?)
10:20
sasha_c
guesst: Please remember that the quality of the images in our current post is not an indication of what the final quality will look like when Axiom is ready and we have refined our image processing algorithms.
10:23
guesst
hard to believe that
10:36
mars_
i'd like to see the full picture, if that is possible
10:37
mars_
(and i really like the fan image)
10:42
sasha_c
guesst: Why is that hard to believe?
10:43
guesst
if you got noise, you got noise. no miracle algo can help you in that

>ougly contraption with a fan on it because they designed it to overheat
14:39
se6astian
This sums up all open source endeavors.
14:39
se6astian
Its a prototype you mong
14:45
dmj_nova
I especially love the comment about why we're not just using a smartphone processor because that's 4k and doesn't overheat
14:45
se6astian
classic
14:45
dmj_nova
to be fair though, doing so wouldn't be a bad idea if Hollywood would accept such a camera for production
14:46
dmj_nova
you know, replace the REDs with smartphones
14:46
dmj_nova
:P
14:47
dmj_nova
still, awesome job on the prototype

Bertl: off the top of your head, is scene_halogen_2ms_c2.raw16 flipped ?
22:31
FergusL
trying to have my vng algo to work with it
22:33
Bertl
all the newer images are 'flipped' so that the image looks 'normal'
22:34
Bertl
(the flipping works vertically)
22:35
FergusL
okay... so...
22:36
Bertl
the only difference to the 'colors*' image is the bayer order
22:36
Bertl
i.e. RGGB becomes GBRG
22:36
Bertl
(and vice versa)
22:36
FergusL
yes
22:36
FergusL
but the bayer order is kind off hard coded in my code
22:36
FergusL
yes, it is ugly
22:36
Bertl
so simply flip the image vertically first, do your stuff and flip it again
22:37
FergusL
yes but I'm starting on the raw data
22:37
Bertl
imagemagick can do that in a few seconds
22:37
FergusL
I'm considering first dumping the .raw16 to a non-destructive high bitdepth format
22:37
Bertl
imagemagick doesn't care if it is raw or not
22:37
FergusL
flipping it at the same time
22:37
FergusL
well I guess it doesn't work directly on the .raw16 ?
22:38
Bertl
sure, just specify the format
22:38
FergusL
?!
22:38
Bertl
display -size 4096x3072 -depth 16 gray:some.raw16
22:39
FergusL
but I'm worried it's going to bake something, assume it's an image that'll be displayed
22:39
FergusL
wow I'm speechless, I was far from thinking that would work...
22:41
Bertl
xzcat scene_ir850_211ms.raw16.xz | display -size 4096x3072 -depth 16 gray:-
22:41
Bertl
xzcat scene_ir850_211ms.raw16.xz | display -size 4096x3072 -depth 16 -flip gray:-
22:41
Bertl
and similar
22:42
Bertl
convert -size 4096x3072 -depth 16 -flip gray:input.raw16 gray:output.flipped.raw16
22:43
Bertl
so not really a big deal ...
22:43
FergusL
ok thanks
22:43
Bertl
np
22:43
Bertl
off for a nap now ... have fun!
