Good Morning!

Nevermind, Fixed :)

darktable vs rawtherapee - what are your thoughts on this? I have just some (I'd say limited) rawtherapee experience, so I'd like to take the opportunity to get more insights into these (or any other open source & free alternatives) as to decide on a path to follow

you = everyone here, feel free to share input

TofuLynx: great to hear

Used both, darktable for me

could you elaborate on that (amount of controls)?

I see. I should give darktable a spin then

I think rawtherapee is offering just as much control/development options by now

hopefully this will help structure pages a bit better

the images seem a bit off

morning folks!

BAndiT1983: Are you there?

Hey :)

yes

very good

*optimization

when I use O3 or O2 it doesnt affect the speed at all, which is strange

yeah

Okay

File loading and saving is memory bound, right?

so it cant really be accelerated, correct?

yep, meant by file loading the steps which are taken after it'S in the memory

maybe memory mapping would be useful for it

yes

there are several loops here and there, but i don't want to use SIMD at the moment, for byte swapping and processing

quick reboot

loading?

Isn't the memory mapping stuff related to the loading pipeline?

simd was mentioned as possible improvement for extractor

I will use the improvements made in GEDI for bilinear and for shoodak

and then I will document the new algorithms which will mark the end of what I proposed in my proposal. Then I can start working on that task

Later I would like to do the video playing

Great :)

I will be right back

Back

hello ArunM!

Bertl are you available after the meeting?

good evening everyone

nmdis199-: contacted me beforehand to be excused from todays meeting

Hello everyone

Here is the architecture

The architecture is yet to be discussed with BertL, already started programming because I wanted to check the possible patterns that can be generated

During simplification of old code i got stuck in changing one design for another and then changing next module.

along with the generator module

New patterns will be updated and discussed by tomorrow only.

How did you make the diagrams?

oh nice :)

the architecture

sounds good!

ArunM: all done?

right, TofuLynx you are next in line

So my task for the last week was to accelerate Bilinear, GEDI and SHOODAK demosaicers

which was giving each color channel to each thread

however, BAndiT1983 quickly pointed that I could distribute the threads inside each loop

Yesterday and today I noticed that there was a condition in every loop that I thought it was slowing things down

At the end, it improved from 67ms to 5ms, which is great.

very nice!

and see where further improvements can be made

because, as openMP distributes the workload for the CPU threads

a more common computer only has four threads

That's all, se6astian :)

can you already estimate a 4096x3072 image processing time?

ah, excellent

on the CPU, if we left the workload to the GPU, it would be even faster

that sounds a lot faster than current hdmi4k / raw2dng stuff :D

you need to leave the computer overnight for a tiny clip :P

don't forget, that it'S just debayering, so numbers will shrink

anyone else who wants to report

ymc98_2: ping?

I will use the time to report a bit myself: the next team talk video and article are almost ready for release

what are the topics of the team talk video?

and you :)

Great! :)

twitter posts about your recent progress:

910 impressions

what are impressions?

it means that it appeared on someones screen

and a comment for magiclantern forum :D

Present

many thanks to all participants

TofuLynx: what do you think of the task of creating some screencaptures of OC in general and what you added so far?

For now, there's just one difference

It was revamped by BAndiT1983

off to bed
