Abstract In this paper, a new fast algorithm for computing watershed in digital grayscale images is introduced. The presented algorithm is based on drain process. The flooding process of traditional algorithm is replaced by finding regional maximum on curve of section .The results show that the proposed one has lower memory requirement and is much faster than the traditional one. Moreover, it combines with recognition which can control the complexity of the segmentation to reduce the over segmentation and computing complexity.
