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.

圖像分割是指從圖像中提取感興趣的區(qū)域,由于人體組織的特性,,醫(yī)學圖像邊界模糊以及對比度低,使得醫(yī)學圖像分割成為一個難點[1],。文獻[2]提出一種基于二進制交叉的實數(shù)編碼遺傳算法的腦部圖像多級閾值分割方法,。文獻[3]提出一種基于螢火蟲算法的二維熵多閾值圖像分割算法,該方法可以有效提高圖像的分割速度,,但由于搜索空間的局限性,,圖像分割精度較低。文獻[4]運用粒子群算法對二維Tsallis熵的參數(shù)q進行優(yōu)化選擇,,該方法可以較好地分割圖像,。文獻[5]針對二維最大熵分割圖像存在計算量大的問題,將人工蜂群算法應用于二維最大熵優(yōu)化,,結果表明,,該方法抗噪性強且收斂速度快。
本文為提高醫(yī)學圖像分割的效果,針對二維Tsallis熵閾值法圖像分割效果受參數(shù)q選擇的影響,,提出一種基于云模型螢火蟲算法優(yōu)化二維Tsallis熵的醫(yī)學圖像分割算法,。最后通過仿真研究,證明了本文算法的有效性,。
