Re: [Gimp-developer] AI algorithms in GIMP


When people say "AI" here do they mean Neural Networks?

"Intelligent" algorithms have been implemented in GIMP for many years.
About 15 years ago, this algorithm got integrated into GIMP:

Now, the reason I bring this is up is that any machine learning algorithm
needs extensive empirical testing and we setup frameworks for
that during the integration of the above algorithm. So whatever machine
learning you want to integrate in GIMP needs to come with an
independent benchmark dataset that is annotated for what you want to
achieve. This benchmark dataset is used AFTER you think you
are ready with building your algorithm.
This is, after you have trained and tested your machine learner (using yet
completely different datasets) and minimized parameters
for generalization, the benchmark dataset does not only further test
accuracy and generalization but also computational efficiency
and user experience. Question like how can the user correct errors of the
AI need to be answered too.

On a further note, if you did this benchmark testing, you would find that
waifu2x is scam. This is, it only works with a very specialized
set of images. The first thing to investigate would be what set of images
that is and how to explain that to a GIMP user. In general, images
cannot be upscaled. The data processing inequality mathematically proofs
that information cannot be created by processing an image.
So, while many TV crime shows suggest this, algorithmically zooming into a
blurry license plate or face to make it recognizable is physically
and mathematically impossible. An independent benchmark set would show the
limits of this algorithm.

Just my two cents,

Something like waifu2x would be fabulous to have in GIMP (a neural
network-based image upscaling algorithm).
