Abstract:

The Intersecting Cortical Model (ICM) is adopted for image segmentation. Because the nonlinear exponential attenuation threshold mechanism is suitable for brightness respondence but not suitable for image segmentation, we change it to the linear threshold mechanism which leads to the LT-ICM. Meanwhile, an improved 2-D Tsallis cross-entropy segmentation rule is proposed for determining the segmentation threshold and iteration time automatically. Experiments show that the proposed algorithm is better than OSTU and K-means algorithms for the texture image segmentation. Besides, our rule is more effective than the 2-D max-Shannon-entropy rule, traditional 2-D Tsallis cross-entropy rule, and min-cross-entropy rule.
