Image Segmenter

Segment an image by refining regions


The Image Segmenter app lets you segment an image using the active contours (also called snakes) algorithm. Using this app, you first create an initial segmentation that defines seed locations and then segment the image iteratively.

Open the Image Segmenter App

  • MATLAB® Toolstrip: Open the Apps tab, under Image Processing and Computer Vision, click the Image Segmenter app icon.

  • MATLAB command prompt: Enter imageSegmenter.
