WebThinning. Common Names: Thinning Brief Description. Thinning is a morphological operation that is used to remove selected foreground pixels from binary images, somewhat like erosion or opening.It can be used for several applications, but is particularly useful for skeletonization.In this mode it is commonly used to tidy up the output of edge detectors … WebMay 29, 2012 · Solution 1. Please try this: This is a morphological image processing. As an example of algorithm: Iteratively delete (or erode) pixels inside the object (letter) to shrink it without shortening it or breaking it apart. Note that this is an iterative process. In general, you may stop the iteration after several times.
