Thinning algorithm in image processing
WebParallel thinning in discrete grids is a topic that has been studied since the pioneering years of digital image processing. The most essential requirement for a skeletonization method is topology preservation, hence the abundant literature devoted to the study of conditions under which a thinning method meets this requirement. WebFeb 8, 2024 · Thinning and skeletonization are extreme forms of morphological processing, and are used when only the fundamental shape of an object on the image is of interest. Thinning transforms objects on a binary image to a set of simple digital lines (or arcs), which lie roughly along the objects’ medial axis (center line).

WebAbstract. Thinning algorithms have been studied widely in picture processing and pattern recognition because they offer a way of simplifying pictorial forms. Figure 9.1 illustrates a motivation for a thinning algorithm. The shaded pixels represent a quantization of a line drawing to be mapped back into a set of lines. WebApr 2, 2012 · There is a actually an algorithm for that called Zhang-Suen thinning algorithm. You can find its code here: http://rosettacode.org/wiki/Zhang-Suen_thinning_algorithm Also I wrote a vectorized version of that in Python which is around 10 times faster than that code. Here is the code:
WebThis is original image: This is skeleton image: This is thinned image: As you can see, skeleton image and thinned image have different results. Thinned image has lesser lines and produce an outline that looks more like the thinned original. But these images are in 2D, I am looking for an algorithm to do thinned binary image in 3D. WebThinning algorithm removes some selected foreground pixels from the binary/binary inverse images. Thinning is somewhat like erosion of the original image. Thinning method Iterative Thinning Iterative thinning algorithms perform pixel by-pixel operations until a suitable skeleton is obtained. I. Stentiford Thinning Algorithm II.
