POLY2MASK and ROIPOLY – Part 3

Posted by Steve Eddins,

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... read more >>

POLY2MASK and ROIPOLY – Part 2

Posted by Steve Eddins,

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... read more >>

POLY2MASK and ROIPOLY – Part 1 19

Posted by Steve Eddins,

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... read more >>
