WebThe scoring function in Harris Corner Detector was given by: R =λ1λ2−k(λ1+λ2)2 R = λ 1 λ 2 − k ( λ 1 + λ 2) 2 Instead of this, Shi-Tomasi proposed: R =min(λ1,λ2) R = m i n ( λ 1, λ 2) If it is greater than a … WebIn your computation of the corner response H = (A. B - C) - lambda (A+B).^2; (A.*B - C) is the determinant (A + B) is the trace This is incorrect, because you are not taking the determinant and trace of the M matrix. Instead, you are simply taking the determinant and trace about each pixel location.

The idea is that a pixel is defined as a corner only if it has big gradients in 2 perpendicular directions, which means the M matrix has 2 big eigenvalues (1 big eigenvalue will simply be an edge). Here we can see Harris detector's free parameter ...
