ofxPolyfit

Thursday, May 5th, 2011

Just a quick note to introduce ofxPolyfit. It’s an openFrameworks extension which allows you to correlate between any 2 numerical datasets of the same or different dimensionality. e.g. a stereo cam is 2x2D, and you want to get 3D, so you could use ofxPolyfit to create your 4D->3D correlation.

ofxPolyfit also encompasses Padé calibration for projection mapping, but this isn’t easily accessible as yet. I’m likely going to be working on this over the next couple of days.

Latest news is that I’ve added a simple RANSAC implementation which lets you filter out good data from poor datasets. This is to be used with our tree projection experiments to filter out bad voxels.

Also in the future I’ll be looking into making the code much more ‘chunky’ by identifying and classifying data sets, coefficient results, basis shapes, etc.
