Segmentation plays an important role in image processing, machine vision, pattern recognition and so on. Numerous segmentation methods based on bi-level thresholding have been proposed, assuming there are only two main populations in an image. However, for a complex image consisting of more populations, a multilevel thresholding is required. This paper presents a new hierarchical segmentation method...
In this paper, we present a new thresholding approach by local fuzzy entropy based competitive fuzzy edge detection for image segmentation which assign appropriate threshold effectively and reduces the affects of noise in edge detection and segmentation. In this algorithm first, edges detected by fuzzy logic and competitive rules, then there would be improvement in quality obtained edges by fuzzy...
