Region growing - Wikipedia

Region growing is a simple region-based image segmentation method. It is also classified as a pixel-based image segmentation method since it involves the selection of initial seed points . This approach to segmentation examines neighboring pixels of initial seed points and determines whether the pixel neighbors should be added to the region.

Image segmentation - Wikipedia

In computer vision, image segmentation is the process of partitioning a digital image into multiple segments (sets of pixels, also known as super-pixels). The goal of segmentation is to simplify and/or change the representation of an image into something that is more meaningful and easier to analyze.
