Improved order-invariant watershed algorithm for image segmentation. (Chinese. English summary) Zbl 1173.94346

Summary: Creative lake minimum is introduced to represent topographical information of a pixel, so as to reduce the number of RIDGE labels in order-invariant watershed algorithm. Watershed fall is used to reduce the number of over-segmented regions. This algorithm is implemented in both immersion and toboggan ways. Experiment results show that the proposed algorithm is still order-invariant, and it can reduce the number of RIDGE labels by about 80% as well as segmented regions by 5% 20%.
