Project Info:

This project is more of a proof of concept of advancements in Digital Noise Reduction algorithms, and that DNR no longer needs to be considered a wholly destructive process. The algorithm I used for this can by found at https://arxiv.org/pdf/1811.12758.pdf which is a GPU-accelerated neural-network based non-local denoising algorithm.

I chose this movie for a couple reasons:

But check out the results of the DNR algorithm in this shot: Group Captain Lionel Mandrake's uniform goes from a noisy, homogeneous uniform, to a heather wool pattern. And the logo resting on top of the computer goes from a blurry mess to a clearly legible "IBM 7090" text.

This will probably take a couple weeks given the denoising processing power required (each frame takes a couple minutes) but I'll keep this updated on features of note, or ask any questions if there are any stylistic choices I'm stuck choosing between.

I chose this movie for a couple reasons:

- It was given a 4K HDR release relatively recently, meaning the film grain would be essentially losslessly preserved from the scan.

- It's black and white, which reduces the processing power required by 2/3s relative to color film.

- It's my favorite movie.
