Fast 2D cumulative residual Tsallis entropy threshold segmentation method
For images with bimodal gray-level histogram, the traditional two-dimensional histogram threshold segmentation method is more effective, but when gray-level histogram is non-peak, unimodal or multimodal, their segmentation results are poor. Considering that the two-dimensional survival function obtained by two-dimensional histogram mapping has the advantages of continuous density and uniform morphology, a fast two-dimensional cumulative residual Tsallis entropy threshold segmentation method is proposed based on the two-dimensional survival function of images. The method firstly constructs a two-dimensional survival function based on the two-dimensional histogram, and then a two-dimensional cumulative residual Tsallis entropy objective function is defined to compute the segmentation threshold on the basis of the two-dimensional survival function. Further, a recursive algorithm is used to reduce time complexity of calculating the objective function to
