WebThinning is a very important preprocessing step for the analysis and recognition of different types of images. Thinning is the process of minimizing the width of a line, in an image, from many ... Webthickening is to determine the skeleton by zone of influence, or SKIZ. The SKIZ is a skeletal structure that divides an image into regions, each of which contains just one of the distinct objects in the image. The boundaries are drawn such that all points within a particular boundary are closer to the binary object contained within
