摘要：As a typical feature of the ocean flow field, the vortex plays an important role in the transmission and distribution of marine matter and energy, and thus becomes a hot spot of feature extraction. In this paper, the vortex extraction is carried out based on the algorithm of compact ratio. In order to further verify its rationality and accuracy, the sea surface height data in the same area is used to test, which proves the feasibility of this method in vortex extraction. In addition, the compact ratio method for extracting vortex is less affected by data resolution, and incorporates the idea of mathematical morphology to provide a new idea for ocean vortex extraction.
