چکیده

A new multi-level thresholding method is proposed using Sample Moment Function (SMF). For the binary case the method can make use of the a priori information on whether the target object is found on the darker or lighter part of the scene. Extensive comparisons using a database of NDT images show that the proposed method outperforms in competition 40 other thresholding methods from the literature [1][2], based upon both objective scores and subjective evaluation.

Color image segmentation using histogram multithresholding and fusion

A novel method for multiband image segmentation has been proposed. The method is based on segmentation of subsets of bands using multithresholding followed by the fusion of the resulting segmentation achannelso. For color images the band subsets are chosen as the RB, RG and BG pairs, whose two-dimensional histograms are processed via a peak-picking algorithm to effect multithresholding. The seg...

Neural Network Performance Analysis for Real Time Hand Gesture Tracking Based on Hu Moment and Hybrid Features

This paper presents a comparison study between the multilayer perceptron (MLP) and radial basis function (RBF) neural networks with supervised learning and back propagation algorithm to track hand gestures. Both networks have two output classes which are hand and face. Skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...

Bridging Quantitative and Qualitative of Glaucoma Detection

Glaucoma diagnosis involves extracting three features of the fundus image; optic cup, optic disc and vernacular. Present manual diagnosis is expensive, tedious and time consuming. A number of researches have been conducted to automate this process. However, the variability between the diagnostic capability of an automated system and ophthalmologist has yet to be established. This paper discusse...

Multithresholding of mixed-type documents

Mixed-type documents include text, drawings and graphics regions. It is obvious that a technique that can reduce the number of the gray-levels in accordance with the type of each document region could be important for many document applications, such as storage, transmission and recognition. To solve this problem, this paper proposes a new method, called the document multithresholding technique...
