This is the first post in a short series on index techniques that are particularly useful for image processing in MATLAB. I'll start with logical indexing today. Later I'll cover linear... 더 읽어보기 >>

Toward the end of last year, it occurred to me that I had accumulated enough material on this blog to construct a "master class" on image processing in MATLAB. The response to my... 더 읽어보기 >>

Happy New Year everyone! I just wrapped up a second year of blogging about image processing in MATLAB. I write once or twice a week about image processing algorithms, image processing... 더 읽어보기 >>

Have you ever used the distance transform? For a binary image, the distance transform is the distance from every pixel to the nearest foreground (nonzero) pixel. (Sometimes you'll see... 더 읽어보기 >>
