Characteristic analysis of Otsu threshold and its applications
TLDR
This paper proves that Otsu threshold is equal to the average of the mean levels of two classes partitioned by this threshold, and proposes an improved Otsi algorithm that constrains the search range of gray levels.About:

An improved Otsu method using the weighted object variance for defect detection
TL;DR: An improved Otsu method, named the weighted object variance (WOV), is proposed in this research to detect defects on product surfaces and provides better segmentation results.
Journal ArticleDOI
A New Iterative Triclass Thresholding Technique in Image Segmentation
TL;DR: A new method in image segmentation that is based on Otsu's method but iteratively searches for subregions of the image for segmentation, instead of treating the full image as a whole region for processing is presented.

Survey over image thresholding techniques and quantitative performance evaluation
Mehmet Sezgin,Bulent Sankur +1 more
TL;DR: 40 selected thresholding methods from various categories are compared in the context of nondestructive testing applications as well as for document images, and the thresholding algorithms that perform uniformly better over nonde- structive testing and document image applications are identified.

A new method for gray-level picture thresholding using the entropy of the histogram
TL;DR: Two methods of entropic thresholding proposed by Pun (Signal Process.,2, 1980, 223–237;Comput.16, 1981, 210–239) have been carefully and critically examined and a new method with a sound theoretical foundation is proposed.
