[IMPOSSIBLE] dual ISO H.264

i guess that is time to say that we need this particular kind of spirit even less.

This dudes been on a rant since his first post in this thread... he even argues with himself.

I failed horribly in math class, but I did do pretty damn good in government and social studies. I'll just say this. You don't have to like the leadership, but you still show them respect for their hard work and knowledge. Wow...

[glubber]

Speechless!

is there an ignore function on the board?

...waiting for everyone to gather their pitchforks and torches...

@all except for apefos: Did I call it in Reply #46, or what? What, right? Cheers!

I think the Leadership, the Master cannot discourage the padawans without showing a proof that things will not work.

In this moment, the Leadership, the Master, just have a theory that things will not work, not an experiment, a real proof.

And me, the padawan, I already found the waves behavior and I have an algorithm that worked in the first lines reconstruction test, so I have the first proof that things can work.

So, due to this, I believe that the discouraging behavior of the Leadership, the Master, is a disrespect to me and to all padawans, because if we are in an open source environment, we all have the rights of doing our attempts.

Yes, me, myself, as a padawan, I lost my temper, my bad. But me, myself, as a padawan, I do not need to endure the disrespect from the Leadership, the Master, discouraging me and all the others without any proof.

Probably you all are waiting for me to say sorry. So, I say sorry, many times as needed. But respect my attempts, do not say impossible without any proof, stop discouraging all the people who are willing to help this development.

By the statement "Impossible" have your ambition now be so great to get it to work!

If it's possible now or later.

And if it will not work, it is so, and you are an experience richer.

Let us continue to participate in your results and do your own experiences.

@apefos - dude, you better watch your tone and i am not even going to quote from you , it is really hard to read such things. You have an idea - thats good, continue and be happy but DO NOT disrespect people, especially the ones, who we- all ML users - owe so much!

Lol.

Yeah he is as bad as that other character that popped up and got banned pretty quick.

I do think this guy is troll, or part troll. He also spams posts with irrelevant information.

Am I safe to say most people want to see him muted?

Apart from bizarre outbursts... I tested it and found that the resolution loss to great. The alternating lines were not well formed (reconstructed with aliasing?) and so created many artefacts when merged. Also there is the small issue of loosing half your vertical resolution! You can't actually reconstruct detail from these large interlacing lines.

Here's a real-world test image (100/1600, exposed with ETTR):


If you are able to recover it, I'll give up on engineering and start growing mushrooms instead.

Hopefully this completes the proof for all the non-believers.

that kind of that you get in dark corners of underground railway stations for money?

[arrinkiiii]

...start growing mushrooms...

Not so bad idea... but please, don't leave  engineering!!!

All I am saying "Give peace a chance!"

That's a bit 'specific' g3gg0 


...which station?

Well, I tried to... Maybe at some point someone manages to get a better quality...

Just as a suggestion, couldn't this interlacing be done like the ML HDR thing? We alternate which lines use high/low ISO every frame, and then compose on post?

[a1ex]

Nice try, but I'm not impressed. The sky shouldn't be gray, and neither the roof.

I'm down for some mushrooms.

If  you eat poisonous mushrooms it will look like that :

Magic Lantern... Magic Mushrooms... THIS must be the inspiration! And I was wondering how you devs could handle all that coding (and even seem to have fun doing it...) @A1ex, please post some growing instructions, maybe we can all become coding geniuses like you!
PD: Glad this thread took on such 'positive' tone after all!

[darkstarr]

@a1ex if you think it will not work no problem, but other people are free to do tests if they want, so stop bothering us and go work in your raw tasks. you are the main developer but you made this thing open source so please respect it's nature. we have the module enabled, we do not need you and your "impossible words"anymore, let us try our success or our fail alone, you are fired of dual iso h264 development, SHUT YOUR MOUTH AND GO AWAY, NOW!

LOL???

where did that come from hahaha!

[Rshred]

This thread seems to have died but I have been playing around with Apefos' workflow for Dual Iso h.264

I tried in the Apefos Dual Iso software and these are my results, the image recorded in dual iso and the image after processing in the software and merged in the hdr software.
 
The Apefos Dual Iso works with JPG, BMP and TIF files. You need to convert the MOV video into a image sequence before using the software.
The software automaticaly batch process all images in the directory, it opens the image, apply the luminance factor numbers to correct the luminance for each line and extracts the low iso and the hi iso lines. After this the software interpolates the low and high iso image separately to recreate the missing lines. With these two recreated images you need to use a hdr software to merge the two images into a single hdr image because the Apefos software does not do the merge.
 
Apefos is using the most simple interpolation method, an average value from the pixel above and below. this simple interpolation method does not removes the aliasing. he also says in the to-do txt file he created a conversion for eliminate the 2 and 3 lines interval to make the image to be 2 lines interval, the same of dual iso raw, but this is not implemented in the beta software yet.
 
Another thing that is not perfect is the luminance correction in the lines. He is using 32 values, so some areas of the image keeps with some lines strip. In the to do txt file he says he already calculated 946 luminance correction numbers, but this is not implemented in the software yet.
 
The results are not satisfactory for use, but the software is in a interesting stage.

Apefos is still working hard on perfecting this workflow.

So, are you able to challenge my proof or recover the colors from my test image?

[tweak]

Well that was entertaining... now where's my dual ISO H.264??? I didn't read this whole thread to come up empty handed  .
