Description

Detects corner by what is know in the machine vision world as the Harris Detector. It works by computing the intensity change along all direction which can be quantified by sum-of-squared-difference and summing these in a Gaussian distribution. Computing the eigenvalues (lamba1 and lamb2) is a measure of corner strength if both eigenvalues are over a specified threshold.
