A Comparative Study of Thresholding Based Defect Detection Techniques

Abstract

This paper presents a comprehensive literature analysis of defect detection techniques. There are several techniques for image segmentation developed by the analyst in turn to make images lustrous and simple to evaluate. In digital image processing, the thresholding is a renowned technique for the segmentation of images. Defect detection is currently a practicable field for improvising performance as well as retaining the products quality. The extensive applications of common thresholding methods such as adaptive thresholding, Otsu thresholding and seven other thresholding techniques have been discussed. In this paper, a comparative study of detection of defect or crack using various thresholding techniques is conferred.
