Image segmentation is the foundation of object recognition and computer vision. Watershed transform is usually adopted for image segmentation in the area of image processing and image analysis because it always generates closed contours for each region in the original image. The concept of watershed transform is based on a processing simulating the immersion of a landscape in a lake that is dams have to be built to prevent the merging of different catchment basins. But the watershed transformation leads to over segmentation. In this paper, the authors will discuss the image segmentation by improved watershed transformation in MATLAB programming environment.
