John Resig - Using Waifu2x to Upscale Japanese Prints
In my spare time I’ve been working on a database of Japanese prints for a little over 3.5 years now. I’m fully aware that I’ve never actually written about this, personally very important, project on my blog — until now. Unfortunately this isn’t a post explaining that project. I do still hope to write more about the intricacies of it, some day, but until that time you can watch this talk I gave at

These days, we’re spoiled with having super-fast processors and high-level libraries to do many things. Well, spoiled is not quite the correct verb, what I mean is that, unless you’re working on some core system code or an inc

Active Shape Models with Stasm
Stasm is a C++ software library for finding features in faces. You give it an image of a face and it returns the positions of the facial features. Stasm is based on the Active Shape Model of Tim Cootes and his colleagues. Stasm is designed to work on front views of faces with neutral expressions. It performed very well in an independent 2013 comparative study. Source code is provided under a BSD s
