Reimplementation of the code in a different language does not remove IP.
The paper is properly cited in libavfilter/vf_sr.c.
I not specialist in IP rights but there is nothing novel in the code
(TBH there is no code at all, look at srcnn.m) it is just plain
convolution, basic math machinery, we are just applying a bunch of
filter convolution to an image.
Well, either it is based on a paper and the matlab code, or it is not.
If it is, it's a big issue, since this is not open source compatible.
If it is just convolution, then why is it based on this paper?
What is the source of those numbers?
If you're referring to using his trained data, Ok, we could train our
own weights if it is really an issue.
Sorry, but you need to be able to give the source of your code. Aka the
original source that can create the code.
I was planning to document this filter this coming weekend, but if
there's serious doubt over its inclusion, I'll wait.
