Hello It's me again, I want to let you know that I' m still working on the clean up. Thanks for cleaning the audio tomfrom994, one thing less to do.

I'm stuck at clean up black lines while I look at 2 valid choices:

1- Remove black lines and reunite the image (optional use JPEG smoothing algorythm for better result). Status: Done

2- Instead of removing black lines, fill them with interpolation of other pixels near the black zone. Status: In Process

I will upload soon both results and let you decide which improve better the image.

If someone have thought about other ways or wanna try by himself you can use the image 6 post up (the one with perspective view corrected).

When we got the image cleaned right, MATLAB will use appropiate algorythm clean automatically (Hardest step) the 3900 images of the entire video then we will use the cleaned audio and the cleaned images in order to mount the video again (Easy step).
Where ever Asuka (Soryu) is, I will manage to get there.

You're welcome.

As I promised here you have the 2 ways of cleaning, please judge it and tell me how you want the video with remove method or interpolation one.

Personally I prefer way of interpolation but if you all decide the remove way I will make the video with it.

Image examples  SPOILER: Show
Original Caption of the video "Goddess Asuka":

Image

Perspective Restored with ratio method improved (1920x1080 like the original):

Image

Now the 2 ways of cleaning black lines.

1- REMOVE BLACK LINES METHOD (as you can see ratio is lost):

Image

2- INTERPOLATE BLACK LINES METHOD (ratio retained, pixels aproximated by near zones values)

Image


I prefer 2nd method, as you can see still some black lines are in it, this is because the mask I used for interpolate pixels isn't perfect, when it is, there will be no black lines.

We won't obtain perfect image because we cant recreate the original pixels that weren't on it.

When you decide which is better MATLAB will automatize the process for all 3906 captions of the video ( yeh I love Asuka, evangelion and so but I WONT do it manually XD)

I'd say interpolation myself.

Oh yeah, whenever you do clean up the black lines and upload the images, please be sure to spoiler tag the images.

Thanks for doing this! :)

Yeah, thank you! Oh, and go for the 2nd method. Looks a great deal better.

Yes! The second method looks great! Once you get the video running, I'm sure the interpolated pixels will be barely noticeable. Keep it up!

No.

But I applaud people for doing something productive. It's at least a challenge someone has set for themselves to overcome. I personally can wait for Khara to release this trailer online in 1080p sometime between now & Nov 17.

I'm not so sure they will. I kind of feel like, if they were going to, they would have already. Since they (apparently) want to keep the story under wraps for now, maybe they're OK with the fan footage being the only version.

All votes to interpolation good choice. As Gendo's Papa said I'm doing this because I consider that a challenge, and resolving It fills some feelings I have towards evangelion series, sure some of you have them also.

Now talking about the process I'm on last and hardest thing: Automatize all the process, the main problem is a big one, camera moves = image moves = black lines moves = mask must be moved in order to match black lines for all images.

Hard but not imposible :ritsuko_mug:

The only fear I have is that my PC get burnt as 1 image requires 100 % CPU and like 20 seconds to process it, the 3900 images will take long with 100 % CPU but maybe I can put it on a icebox :douse:

Eh. Even if the whole thing gets released eventually online or as a BD extra, it's a way to flex problem-solving skills and learn new things. Nothing wasteful in that.

Hello It's me, sorry for no updates but all that time I wasn't in my country and cant work on the final step also I was relaxing in nature place where you shouldn't have any digital stuff.

So now I'm on home and I will keep trying last step, It's really hard to complete because pixels moves and I need to move mask in order to match black lines every frame, and the most hard thing is that the movement is not the same, so We are in very hard problem xD

I will keep thinking how to solve that.

I'm still really surprised that the original trailer hasn't been posted online yet. That said, I'm still eagerly looking forward to the fruits of your labor, Josh!

Why are you bothering with the shaky hand held video? Why not use the steady one here:

http://www.youtube.com/watch?v=2EcFm4RFHgo


The hand held video does have better quality though since it is not from such a skewed perspective.

If you want to go with the hand held video you're going to need to code a pixel based feature tracker across frames. This is a pain since there's not a lot of static features, too dark, lots of noise, variable brightness of projected video distorts the luminosity of surrounding building features, and so on.

If you want the hand-held one because it has better video, you can always do it like this:
1) Take the steady one posted above, and slice out the video from the rest of the building. It should be easy since the camera is not moving much. Then transform the perspective for that slice.

2) Process the shaky one, and transform the whole image including the building by a best-guess-perspective. Do this because you necessarily do not know where in the image is the projected video itself.

3) Scan for the frame gotten from the steady video in the transformed shaky one. You can brute force this by sliding the frame from step 1 over the frame in step 2, then finding the point of lowest difference.

4) Use the coordinates acquired from step 3 to rip out the larger image from the shaky video.
In and of itself, self-evident.
