Free registration required

Executive Summary

In this paper, an automatic multilevel thresholding Method for Image segmentation is proposed based on Discrete Wavelet Transforms and Genetic Algorithm. The authors have combined Genetic Algorithm with DWT to make Segmentation faster and adequate results. First the length of the histogram is reduced by using DWT. Using this Reduced Histogram, the number of Thresholds and Threshold Value are determined by Genetic Algorithm. The Thresholds are then projected in original Space. From the analysis of results, it can be concluded that the proposed method is fast and accurate.
