interest point detection




Interest point detection in computer vision that refers to the detection of interest points for subsequent processing

An interest point is a point in the image which in general can be characterized as follows: It is stable under local and global perturbations in the image domain as illumination/brightness variations, such that the interest points can be reliably computed with high degree of repeatibility.
