WebAug 24, 2024 · This paper presents an extensive review of global thresholding techniques for image segmentation. It includes the various methods used for global threshold selection of grey level images. In this survey, global thresholding methods are divided into two categories: histogram modification and methods that computes threshold. WebAn automatic thresholding method based on Shannon entropy difference and dynamic synergic entropy is proposed to select a reasonable threshold from the gray level image with a unimodal, bimodal or peakless gray level histogram that has more flexible adaptivity of selecting threshold and better segmentation accuracy.
WebThe thresholding algorithms examined include those that exploit spatial information, locally adaptive characteristics, histogram entropy information, histogram shape information, …
