Segmentation Analysis
Topic Overview The Wolfram Language includes a variety of low- and high-level image segmentation techniques from clustering, watershed and region growing to semantic and object segmentation using neural networks. Segmentation functions can be used together with a rich set of functions for pre- and post-processing for more robust results as well as analysis functions performed on the result of the segmentation.
Foreground-Background Separation
RemoveBackground — separate the background from the foreground of the image
ImageSegmentationFilter — segment an object or region in an image
Binary Segmentation
Binarize — segmentation by thresholding pixel intensities
