A robust thresholding algorithm for unimodal image histograms
نویسندگان
چکیده
This article introduces a method to determine the threshold of unimodal image histograms in a robust manner. It is based on a piecewise linear regression that finds the two segments that fit the descending slope of the histogram. The algorithm gives a good estimation of the threshold, and is practically insensitive to the noise distribution, to the quantity of objects to segment, and to random histogram fluctuations.

Robust 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 ...
متن کاملQuantification of neural images using grey difference
We present new algorithms for segmenting neuron images which are taken from cells being grown in culture with oxidative agents. Information from changing images can be used to compare changes in neurons from the Zellweger mice to those from normal mice. Image segmentation is the first and major step for the study of these different types of processes in neuron cells. It is difficult to do it as...
متن کاملTransition thresholds and transition operators for binarization and edge detection
The transition method for image binarization is based on the concept of t-transition pixels, a generalization of edge pixels, and t-transition sets. We introduce a novel unsupervised thresholding for unimodal histograms to estimate the transition sets. We also present dilation and incidence transition operators to refine the transition set. Afterward, we propose the simple edge transition opera...
متن کاملThresholding based on linear diffusion for feature segmentation
Segmentation is an important step in image vision. Computationally efficient methods, such as histogram based algorithms, are preferable for real-time applications. In this paper we developed automatic algorithms based on linear diffusion to segment both unimodal and plurimodal histograms. These algorithms are computationally efficient and do not use default value parameters or other heuristics...
متن کاملUnimodal thresholding
Most thresholding algorithms have difficulties processing images with unimodal distributions. In this paper an algorithm, based on finding a corner in the histogram plot, is proposed that is capable of performing bilevel thresholding of such images. Its effectiveness is demonstrated on synthetic data as well as a variety of real data, showing its successful application to edges, corners, differ...
