Abstract
In this work, we present an implementation and thorough study of the 
Harris corner detector. This feature detector relies on the analysis of 
the eigenvalues of the autocorrelation matrix. The algorithm comprises 
seven steps, including several measures for the classification of 
corners, a generic non-maximum suppression method for selecting interest 
points, and the possibility to obtain the corners position with subpixel 
accuracy. We study each step in detail and propose several alternatives 
for improving the precision and speed. The experiments analyze the 
repeatability rate of the detector using different types of transformations.
