Image Segmenter

Segment an image by refining regions


The Image Segmenter app lets you create a segmentation mask using automatic algorithms such as flood fill, semi-automatic techniques such as graph cut, and manual techniques such as drawing ROIs. You can also refine masks using morphology or an iterative approach such as active contours (also called snakes). For more information about creating, refining, and exporting a segmentation mask, see Getting Started with Image Segmenter.
