Abstract： In order to improve the effect of medical image segmentation, for the effect of two-dimensional Tsallis entropy threshold method，two-dimensional Tsallis Entropy improved by cloudmodel firefly algorithm is applied to medical image segmentation algorithm. Firstly, in order to improve the convergence speed and optimization ability，the cloud model is introduced into the Firefly algorithm. Secondly, the homogeneity measure was chosen as the evaluation index of medical image segmentation, and the parameter q of the two-dimensional Tsallis entropy threshold method was optimized by CMFA algorithm. The results show that CMFA-Tsallis has the highest homogeneity measure compared with FA-Tsallis and Tsallis, and the result boundary is clear, thus proving the effectiveness of this algorithm.
