Segmentation algorithms are used to subdivide entire images at a pixel level, or specific image objects from other domains into smaller image objects.
Trimble provides several different approaches to segmentation, ranging from very simple algorithms, such as chessboard and quadtree-based segmentation, to highly sophisticated methods such as multiresolution segmentation and contrast filter segmentation.
Segmentation algorithms are required whenever you want to create new image objects levels based on image layer information. But they are also a very valuable tool to refine existing image objects by subdividing them into smaller pieces for more detailed analysis.
