Region-based segmentation

Region-based segmentation methods attempt to partition or group regions according to common image properties. These image properties consist of

1. Intensity values from original images, or computed values based on an image operator
2. Textures or patterns that are unique to each type of region
3. Spectral profiles that provide multidimensional image data

Elaborate systems may use a combination of these properties to segment images, while simpler systems may be restricted to a minimal set on properties depending of the type of data available.
