This paper presents an automatic retinal image mosaic method, which is based on the principle of blood vessels resemblance. The method depends on the characteristics of the extracted blood vessels that are segmented by combining mathematical morphology with maximum entropy algorithm. Then, the registration objective function is developed by using the maximal overlap degree of the retinal blood vessels...
To overcome the drawbacks of fuzzy multi-level entropic thresholding algorithm, a modified fuzzy multi-level thresholding algorithm for segmentation of MRI is presented in this paper. The algorithm is different from the entropic thresholding algorithm including two aspects. First, maximum variance criteria is used in the proposed algorithm to overcome the limitation of entropic algorithm, which usually...
