Really enjoyed this article, thanks for sharing!

I had recently learned about using image pyramids[1] in conjunction with template matching algorithms like SAD to do simple and efficient object recognition, it was quite fun.

Image pyramids are a brilliant method. The technique is hiding in many of the FCNN image segmentation models ive read.

A truly clever image processing method.
