Algorithm that solves the Multiple Travelling Salesman Problem (MTPSo) The salesman do not return to their starting location in this algorithm.

In the fields of computer vision and image analysis, the Harris-affine region detector belongs to the category of feature detection. Feature detection is a preprocessing step of several algorithms that rely on identifying characteristic points or interest points so to make correspondences between images, recognize textures, categorize objects or build panoramas.
