Understanding images can be helpful in e-commerce. Image segmentation is a tool used to identify different parts of an image. Recent research has focused on global and local segmentation methods in various fields like medicine, sports, and agriculture. Different techniques like edge-based, fuzzy, threshold, PDE-based, ANN-based, region-based, water shed-based, cluster ensemble-based, and fast trust region segmentation have been explored. These methods help in comparing features of images and influencing customers or retailers by providing detailed information about products.
