The goal of segmentation is to simplify and change the representation of an image into something that is more meaningful and easier to analyze. Here similar looking pixels are grouped together for efficiency of further processing. In segmentation a label is assigned to every pixel in an image such that pixels with same label share certain visual characteristics. There are many methods and algorithms to segment an image. Mean shift Algorithm is also an algorithm which can be used to segment a color image.
