A SURVEY OVER IMAGE THRESHOLDING TECHNIQUES and QUANTITATIVE PERFORMANCE EVALUATION
ثبت نشده
چکیده
In this study we conduct an exhaustive survey of image thresholding methods, categorize them and express their formulae under a uniform notation, and finally carry their performance comparison. The thresholding methods are categorized according to the information they are exploiting, such as: histogram shape, measurement space clustering, entropy, object attributes, spatial correlation and local gray-level surface. Forty selected thresholding methods from various categories are compared in the context of non-destructive testing applications as well as for document images. The comparison is based on the combined performance measures. We identify the thresholding algorithms that perform uniformly better over nondestructive testing and document image applications.

متن کاملA survey of thresholding techniques
In digital image processing, thresholding is a well-known technique for image segmentation. Because of its wide applicability to other areas of the digital image processing, quite a number of thresholding methods have been proposed over the years. In this paper, we present a survey of thresholding techniques and update the earlier survey work by Weszka (Comput. 3-16). We attempt to evaluate the...
متن کاملAn Improved Pixon-Based Approach for Image Segmentation
An improved pixon-based method is proposed in this paper for image segmentation. In thisapproach, a wavelet thresholding technique is initially applied on the image to reduce noise and toslightly smooth the image. This technique causes an image not to be oversegmented when the pixonbasedmethod is used. Indeed, the wavelet thresholding, as a pre-processing step, eliminates theunnecessary details...
متن کاملPerformance Evaluation of Quantitative Metrics on Ancient Text Documents Using Migt
In the present world scenario Optical Character Recognition (OCR) has wide variety of applications in the text document image analysis for recognizing individual characters of any language. Digitizing the old documents is a tough job for preserving the essence of the documents to the coming eras. In this paper we are summarizing different image quantitative metrics for estimating the loss of in...
متن کاملRobust Potato Color Image Segmentation using Adaptive Fuzzy Inference System
Potato image segmentation is an important part of image-based potato defect detection. This paper presents a robust potato color image segmentation through a combination of a fuzzy rule based system, an image thresholding based on Genetic Algorithm (GA) optimization and morphological operators. The proposed potato color image segmentation is robust against variation of background, distance and ...
