# Segmenting Images

The process of segmenting an image is the most unpredictable and difficult aspect of blob analysis, particularly if you are confronted with wide image-to-image variation in image contrast and in the number of blobs. This section describes some of the techniques and tools you can use to segment images effectively.

The more consistent images are, and the more information you know about the image at the time you write your application, the more effective the segmentation approach will be.
