Hi guys, I think Casey's suggestion of super resolution is an excellent idea and would be useful to a lot of people using GIMP. The two algorithms which have been doing quite well are: 1. SRGAN: The relevant paper is at https://arxiv.org/abs/1609.04802 . This has yielded some very nice results so far and is now considered to be state-of-the-art in the computer vision community. Implementing this will be my first priority. 2. SRResNet: The paper is at https://arxiv.org/abs/1609.04802 . This algorithm also gives quite good results. Now to train these neural nets, I will have to prepare a dataset consisting of low resolution and high resolution images and divide them into training, testing and validation sets. I'll try to write a script which pulls high-resolution CC-A/CC0/CC-A-SA images from the internet and downscale them in python to prepare their low resolution counterparts. I only hope that my GPU has enough memory to train the model, otherwise I am done for. What I would like to do is create a python script (most of these libraries are available in Python) and then pass the image along with the scaling factor into this from inside GIMP. I've never worked with GEGL before but I will try finding out how to use this. Since I am working on this in my free time and have not implemented neural nets much, this might take some time for me to learn. I'll try keeping you guys informed. Any suggestions are welcome. Thanks, Maitraya.
