if you do a basic economic optimization you need to assign a value for a human life

aren't you at meeting
Jyrki Alakuijala
2021-04-21 07:21:31
no, Luca and Jon will deal with it very well
2021-04-21 07:21:48

can jpeg xl model verification
2021-04-21 07:22:00
do
2021-04-21 07:22:01
for %i in (C:\Users\User\Documents\jpg.png) do cjxl "%i" "%i.jxl" -I 3.9 -X 8 -P 8 -Q 86.6 -m -s 8 --num_threads=2 for %i in (C:\Users\User\Documents\jxl1.png) do cjxl "%i" "%i.jxl" -q 60.4 -s 4 --faster_decoding=3 --num_threads=2
2021-04-21 07:22:06
same quality as this
Jyrki Alakuijala
2021-04-21 07:22:13
it is not like this ISO meeting is going to make earth shattering new design decisions (or any other ISO meeting)
fab
2021-04-21 07:22:15
or better quality
2021-04-21 07:22:25
i did this with 0.3.5
monad
2021-04-21 07:23:07
Why do you still do I > 1?
fab
2021-04-21 07:23:31
i thought it was I until 5
veluca
2021-04-21 07:24:09
nah, above 1 is exactly 1
fab
2021-04-21 07:25:04
so the quality has improved or it needs tweaking
2021-04-21 07:25:23
or is only efficient for graphical
2021-04-21 07:29:30
in comparison to q 83.2 new heuristics is not bad
2021-04-21 07:29:41
d 1 and d2 are good
2021-04-21 07:30:03
but i want to know lower quality in the q 60.4 ranged
2021-04-21 07:30:20
i think with new builds it will appear more loss
Jyrki Alakuijala
 fab so the quality has improved or it needs tweaking
2021-04-21 07:30:35
quality has improved a lot from 0.3.2 and earlier and even more so against 0.2.x and earlier
2021-04-21 07:31:12
I don't remember exactly when the last patch of quality improvements surfaced, possibly in 0.3.4 or 0.3.3
fab
2021-04-21 07:31:16
from 0.3.7
Jyrki Alakuijala
2021-04-21 07:31:29
oh, that shouldn't be the case
fab
2021-04-21 07:31:31
like it can do better quality than the command i use
2021-04-21 07:31:41
at same distance
Jyrki Alakuijala
2021-04-21 07:31:46
(I didn't even know we have a 0.3.7 already :-D)
2021-04-21 07:32:14
if you compare 0.3. against 0.2. -- yes, a huge improvement
2021-04-21 07:32:22
but 0.2. was not bad
2021-04-21 07:32:42
I'm now back to coding and hope to make further quality improvements
fab
2021-04-21 07:32:46
or more compression less quality
Jyrki Alakuijala
2021-04-21 07:32:57
my next patch of improvements should improve on higher bpp
fab
2021-04-21 07:33:07
i hope it works for all files
2021-04-21 07:33:09
or most
Jyrki Alakuijala
2021-04-21 07:33:15
some improvement on low bpp, too
fab
2021-04-21 07:33:19
even if you sacrifice quality for compression
2021-04-21 07:33:33
at lower bpp
Jyrki Alakuijala
2021-04-21 07:33:43
but make the higher bpp compression not only more effective but 'safer', less surprise anywhere in the image
2021-04-21 07:33:59
yes, it should become a lot safer
2021-04-21 07:34:19
I don't know yet how slow it will be, possibly in -s 8
fab
2021-04-21 07:34:26
i want x3 compression
2021-04-21 07:34:34
from 171 kb to 60 kb
Jyrki Alakuijala
2021-04-21 07:34:47
x3 from jpeg size?
fab
2021-04-21 07:35:02
i think with png is good already
2021-04-21 07:35:08
for screenshots
2021-04-21 07:35:25
as long itworks
2021-04-21 07:35:37
current i have like 87 kb from 171 kb
2021-04-21 07:35:53
and 0.3.5
2021-04-21 07:37:17
can you do better with that image
2021-04-21 07:37:44
that is a 7z link
2021-04-21 07:37:58
without using same command i used
2021-04-21 07:38:05
so without 2 generation loss
2021-04-21 07:39:41
this don't satisfy me in image quality
2021-04-21 07:39:55
particularly colors
2021-04-21 07:40:04
they look undersaturated
2021-04-21 07:40:37
nhw codec hasn't the same problem more
2021-04-21 07:41:30
but i don't like nhw codec it feels worse than modular to me
2021-04-21 07:41:38
i like block based codecs
Jyrki Alakuijala
2021-04-21 07:50:00
This image we will be able to compress in far future using a new encoder
2021-04-21 07:50:33
the context modeling that Jon has been abusing for procedural art can be tamed and it will be able to do massive compression on this kind of material
2021-04-21 07:50:50
I anticipate that we will be able to invest in it in about a year
2021-04-21 07:51:04
it is a very complex problem on how to do it and no one has done it before
fab
2021-04-21 07:51:12
but with lossy
2021-04-21 07:51:22
like why nhw wavelet codec
Jyrki Alakuijala
2021-04-21 07:51:26
yes, we can create loss
fab
2021-04-21 07:51:29
can even with -l7
2021-04-21 07:51:33
have same saturation as original
2021-04-21 07:51:36
and jpeg xl
2021-04-21 07:51:38
not
Jyrki Alakuijala
2021-04-21 07:51:46
without block based, but with similar density
fab
2021-04-21 07:51:56
because jpeg xl is block based
2021-04-21 07:52:02
what is the problem
2021-04-21 07:52:10
or the encoder that isn't optimized
2021-04-21 07:52:14
and undersaturate
2021-04-21 07:52:18
to prevent loss
Jyrki Alakuijala
2021-04-21 07:52:25
do you see undersaturation?
fab
2021-04-21 07:52:43
honestly this image even at lowest quality should look good
Jyrki Alakuijala
2021-04-21 07:52:46
I'm just increasing butteraugli's red-green saturation concern for large differences
fab
2021-04-21 07:53:03
i see undersaturation for that image at lossy varDCT
Jyrki Alakuijala
2021-04-21 07:53:03
(but loosening on very small saturation differences)
fab
2021-04-21 07:53:30
from lower quality to normal d1
2021-04-21 07:54:18
it is very perceived to normal eye
2021-04-21 07:54:53
captured from firefox png
Crixis
2021-04-21 07:57:46
can be a problem of incorrect visualisation of the source png?
fab
2021-04-21 07:59:12
there are many colours
2021-04-21 07:59:26
is not simple as you think
2021-04-21 07:59:47
the font is carrier.
2021-04-21 08:01:47
2021-04-21 08:02:08
is not good as hakuna sans from dafont

2021-04-21 08:28:26
same size as d 1

2021-04-21 09:01:58
yes but all qualities matter

ok i will upload the thumbnail i downloaded in full resolution

they are all 1280x720 jpg
2021-04-21 09:03:02
webp i didn't found and also there is overlay background
2021-04-21 09:03:29
i will use mega.nz al

100 thumbnails of youtube music
2021-04-21 09:11:34
is that windows 10 photo viewer?
2021-04-21 09:11:41
it's a program i don't know
2021-04-21 09:14:36
BUT the great is the nhw codec until -l 7 does even better job at lossy with wavelet algorithms
2021-04-21 09:17:30
and don't lose saturation
2021-04-21 09:22:25
also i have another test problem
Crixis
 fab is that windows 10 photo viewer?
2021-04-21 09:22:47
is QuickLook
2021-04-21 09:25:44
from 9 MB to 7 MB
2021-04-21 09:32:38
without loss
Jyrki Alakuijala
2021-04-21 10:53:05
better is possible
fab
2021-04-21 12:52:44
i don't know if adaptively saturating some image colors at more than -d 2 -d 4 help with the perception
2021-04-21 12:52:48
that's not my job
2021-04-21 12:54:23
maybe i would use lossless
2021-04-21 12:54:40
i did with latest version on default and i had 336 kb
2021-04-21 12:54:55
crixis had 250 kb so it used something different
2021-04-21 12:55:02
or maybe i used random settings
2021-04-21 02:05:27
ok i get 331 kb with default q 100
2021-04-21 02:05:43
so maybe crixis did s 9 E 3
2021-04-21 02:05:53
with ORI.png
diskorduser
 fab i don't know if adaptively saturating some image colors at more than -d 2 -d 4 help with the perception

Saturated colors? I don't see any color changes bw source and jxl even on a calibrated monitor.
fab
2021-04-21 04:11:46
undersaturated
diskorduser
2021-04-21 04:11:57
I think you have issues with color profile
fab
2021-04-21 04:11:58
i see way less colours than original
2021-04-21 04:12:03
not this
2021-04-21 04:12:07
but less saturation
2021-04-21 04:12:20
i didn't counted colours with imagemagick or xnview
2021-04-21 04:12:31
i just downloaded the file crixis created
2021-04-21 04:12:38
i don't have my encoding
diskorduser
2021-04-21 04:12:55
Could you give me the source image? I will test it at my end.
fab
2021-04-21 04:13:37
yes but anyway it can be improved
2021-04-21 04:13:50
the saturation
2021-04-21 04:14:15
even if cjxl derives from pik and pik mission also fuif is to not oversaturate lossy output

2021-04-21 04:17:54
2021-04-21 04:18:26
the colours are pretty different
2021-04-21 04:19:54
2021-04-21 04:20:27
how you can not see the difference
2021-04-21 04:20:49
this is speed 7
2021-04-21 04:21:08
maybe he hasn't the encoder without the group fix
2021-04-21 04:22:15
trying with other viewers
2021-04-21 04:35:51
here's there is und
2021-04-21 04:37:20
this is xnview decoded png with capture tool of windows 7
2021-04-21 04:37:43
but the loss is only few pixels is good png
2021-04-21 04:42:33
nhw codec don't do that
2021-04-21 04:44:28
i didn't see less saturation, but less appealing colours.
2021-04-21 04:46:00
i will try with 2 generation loss
2021-04-21 04:47:18
this is maybe similar to the issue Lee is having
2021-04-21 04:47:23
or correlated
2021-04-21 05:10:56
first re encoding
2021-04-21 05:11:09

no i have another command with 0.37 that i'm trying now
Crixis

oh god what is this mess?
2021-04-21 05:20:20
this is so blocky, how?
2021-04-21 05:21:09
why use Modular lossy?
_wb_
2021-04-21 05:21:42
It is nearly always a bad idea to use Modular lossy
fab
2021-04-21 05:26:34
2021-04-21 05:27:10
this is smaller as i can get with 0.3.7
2021-04-21 05:27:33
but ariana grande face was smoothed
Crixis oh god what is this mess?
2021-04-21 05:28:32
this inflates file size
2021-04-21 05:28:39
indeed better use 0.3.7
2021-04-21 05:28:45
longer encoding time pay off
2021-04-21 05:29:26
i will test with more images to make eyes bleed
Crixis
2021-04-21 05:29:50
this is after 100 rencoding
2021-04-21 05:31:02

2021-04-21 05:45:47

Well it only uses a patch if it can detect at least two copies of the same thing

so something like "G" wouldn't have a patch used, but something like "GGGGGGGG" would use patches?

2021-04-21 07:28:06
and you don't need to re encode
2021-04-21 07:30:27
jyri didn't disappoint
2021-04-21 07:49:27
the best is the encoder is at same speed

600mb ram for a 2000x3000
2021-04-22 07:05:37
it already finised for 30 images
2021-04-22 07:12:25
the other 30% 20% 15% bigger
2021-04-22 07:12:59

2021-04-22 07:13:14

2021-04-22 05:06:51
i heard in 0.239 bpp compression
2021-04-22 05:07:08
when i compressed three images in a row at d1 at that bpp
2021-04-22 05:07:19
also when it failed to read image
2021-04-22 05:07:26
but it was louder
2021-04-22 05:07:50

If cjxl beeps, something very weird must be happening
