Thermal Imaging Experiments

Using the below rig I filmed a NY city street using a thermal camera.

I first take the thermal video and use an optical flow detection library called oflow ( to take the brightest points in each frame of the video to be the "hottest" points:

function isHot(color) {
    return color[0] > 150 && color[1] > 150 && color[2] > 150;

I then run this through three.js. Instead of rendering the "blobs" I use their x,y positions to map my particle system to thier locations each frame.
