The Watershed Algorithm is a popular image segmentation technique used in computer vision. It treats an image like a topographic surface, where pixel intensity represents elevation. The algorithm identifies "watershed lines" that separate different regions, effectively segmenting the image into distinct areas based on gradients. This method is particularly useful for separating touching objects in an image, such as cells in microscopy images. By applying the watershed algorithm, one can enhance the analysis of structures in images, making it easier to identify and quantify features in various applications, including medical imaging and remote sensing.
