Otsu reference proposed a criterion for maximizing the between-class variance of pixel intensity to perform picture thresholding. However, Otsu's method for image segmentation is very time-consuming because of the inefficient formulation of the be- tween-class variance. In this paper, a faster version of Otsu's method is proposed for improving the efficiency of computation for the optimal thresholds of an image. First, a criterion for maximizing a modified between-class variance that is…

Efficient solution of Otsu multilevel image thresholding: A comparative study
A modified Otsu image segment method based on the Rayleigh distribution
TLDR
An improved threshold im- age segmentation algorithm based on the Otsu method is developed, which takes into account that the object and the background in image obey Rayleigh distributions, and the maximum between-cluster variance is modifiedbased on the model.
Framework for efficient optimal multilevel image thresholding
TLDR
This paper defines two classes of objective functions for which the optimal thresholds can be found by efficient algorithms and shows, for example, that the method proposed by Otsu and other well-known methods have objective functions belonging to these classes.

TLDR
The experimental results show that the evolutionary approach achieves a satisfactory segmentation effect and that the processing time can be greatly reduced when the number of thresholds increases.

Efficient Polynomial Implementation of Several Multithresholding Methods for Gray-Level Image Segmentation
TLDR
This work presents a polynomial easy-to-implement dynamic programming algorithm to find the exact optimum thresholds of three well-known criteria functions for multithresholding: the maximum of histogram between class-variance (Otsu’s method); the maximum histogram entropy (Kapur et al.“s method), and minimum histogram error (Kittler and Illingworth”s method).
Fast optimal thresholding based on between-class variance using mixture of log-normal distribution
TLDR
This paper proposes a new method for segmenting images based on Otsu's method by estimating the threshold using a histogram based on between-class variance, and finds the optimal threshold using the first derivative of the BCV relation to obtain iterative equations which then produce the optimal thresholds.

TLDR
The experimental results show that the ACS–Otsu algorithm efficiently speeds up Otsu's method to a great extent and preserves its robustness at multilevel thresholding.
