This AFMM method is a modified version from the original implementation of Alexandru et. . This makes 3DMorph easily scalable and adaptable to different imaging parameters or cell types. Thinning: Thinning is a morphological Jul 19, 2007 · Skeletonization is (roughly speaking) the "thinning" of a binary image or silhouette to a one-pixel width spine. Run the main file Skeltrace. com/matlabcentral/fileexchange/11123-better-skeletonization), MATLAB Central File Exchange. The ImageJ wiki is a community-edited knowledge base on topics relating to ImageJ, a public domain program for processing and analyzing scientific images, and its ecosystem of derivatives and variants, including ImageJ2, Fiji, and others. skeletonize works by making successive passes of the image. Online Octave (MATLAB) Compiler - Edit and Run your Octave code with myCompiler IDE. The skeleton must account for geometrical properties of the form and retain associative relationships.
