摘要：
For the problems in underwater image processing by traditional image detection methods, such as inaccurate location of objects regions, loss of object details and distortion of object shape, etc., a new two-dimensional histogram based on edge information is proposed by utilizing the non-extensive property of Tsallis entropy. The improved particle swarm optimization (PSO) is used to search the best threshold value by maximizing the two-dimensional Tsallis entropy. The test results of some underwater images show that it is efficient to detect objects in underwater images. Comparing with traditional methods, the proposed approach shows better adaptability and robustness.
