What information is hiding within, just under the surface?
Even a badly cropped image of 11 yr old me can reveal structural clues hinted by at the surface appearance.
BMP to Vector is a complicated process with a lot of room for errors to be made. From color to grayscale, then turning into a 1-bit monochrome, corner analysis then finding the right Bezier curve segments is not for the faint of heart. Potrace is at the heart of this, with further simplifications by Inkscape.
Another method I used uses Fourier transform in a clever way but I’ve only seen it in a single app (“Fourier Anime”) and I want to find it elsewhere.
But for now, I’m satisfied with being able to do this and to have a reasonable process for getting here. Maybe it’s built-in to fancy paint programs — I don’t know. All I have is Paint (dot) NET and it took a few tools to go full circle back to it.
But I’m getting closer to understanding a “something”, although I don’t know what that is yet
