This is the final post in a series discussing the algorithm underlying Image Processing Toolbox functions poly2mask and roipoly. (See Part 1 and Part 2.) There are several desirable... 더 읽어보기 >>

I'm familiar with two basic ways to determine whether a point is inside a polygon. The first is to compute the winding number, which is the number of times that a closed curve encircles the... 더 읽어보기 >>

This is the first of several blogs about the algorithm behind poly2mask and roipoly. poly2mask takes a set of polygon vertices and produces a binary mask image. The binary mask has 1s for... 더 읽어보기 >>
