TLDR
A study of unsupervised evaluation criteria that enable the quantification of the quality of an image segmentation result that uses Vinet's measure (correct classification rate) to compare the behavior of the different criteria.
Abstract
We present in this paper a study of unsupervised evaluation criteria that enable the quantification of the quality of an image segmentation result. These evaluation criteria compute some statistics for each region or class in a segmentation result. Such an evaluation criterion can be useful for different applications: the comparison of segmentation results, the automatic choice of the best fitted parameters of a segmentation method for a given image, or the definition of new segmentation methods by optimization. We first present the state of art of unsupervised evaluation, and then, we compare six unsupervised evaluation criteria. For this comparative study, we use a database composed of 8400 synthetic gray-level images segmented in four different ways. Vinet's measure (correct classification rate) is used as an objective criterion to compare the behavior of the different criteria. Finally, we present the experimental results on the segmentation evaluation of a few gray-level natural images.

Some Methods for Strengthening the Common χ 2 Tests

TL;DR: In this article, the authors discuss two kinds of failure to make the best use of x2 tests which I have observed from time to time in reading reports of biological research, and propose a number of methods for strengthening or supplementing the most common uses of the ordinary x2 test.

A possibilistic approach to clustering

TL;DR: An appropriate objective function whose minimum will characterize a good possibilistic partition of the data is constructed, and the membership and prototype update equations are derived from necessary conditions for minimization of the criterion function.
