The magnitude of gradient value is intensely sensitive to image noise. So noise value plays a vital role in watershed processing. In computer-world watershed is a classical algorithm used for image segmentation.

根据官方文档 The function implements one of the variants of watershed, non-parametric marker-based segmentation algorithm, described in [161] . [161] Fernand Meyer. Color image segmentation. In Imag…
The gray value of each pixel in the image represents the elevation of the point, and each minimal local value and its influence area constitute a catchment basin. The basin's boundary is the watershed [7,8], as shown in Fig. 1. The watershed algorithm has a good segmentation effect on ...

To prevent oversegmentation, remove shallow minima from the image by using the imhmin function before you use the watershed function. Algorithms watershed uses the Fernand Meyer algorithm [1]. References [1] Meyer, Fernand, "Topographic distance and watershed lines,” Signal Processing , Vol. 38...
The watershed transformation is a popular image segmentation technique for gray scale images. This paper describes a real-time image segmentation based on a parallel and pipelined watershed algorithm which is designed for hardware implementation. In our algorithm: (1) pixels in a given image are rep...
