The otsu algorithm
WebbThreshold segmentation is a simple and effective method in the field of image segmentation which has the widest application domain. And the improvement of efficiency and precision of the threshold segmentation has received extensive attention and research. Inspired with the bio-inspired intelligent optimization, this paper proposes an Otsu multi … WebbThis algorithm is an implementation of the Otsu thresholding technique [otsu79]. The histogram is divided in two classes and the inter-class variance is minimized. This plugin outputs a thresholded image with the selected threshold. @Article {otsu79, author = "N.

WebbThe existing Otsu segmentation algorithms have deficiencies such as poor anti-noise capability, ignoring the class cohesion and so on. Based on the traditional gray value-neighborhood average gradient Otsu segmentation method, we propose an improved two-dimensional Otsu algorithm for tree image segmentation.
