Graph Cuts Segmentation by Using Local Texture Features of Multiresolution Analysis

This paper proposes an approach to image segmentation using Iterated Graph Cuts based on local texture features of wavelet coefficients. Using Haar Wavelet based Multiresolution Analysis, the lowfrequency range (smoothed image) is used for the n-link and the highfrequency range (local texture features) is used for the t-link along with the color histogram. The proposed method can segment an object region having not only noisy edges and colors similar to the background, but also heavy texture change. Experimental results illustrate the validity of our method. key words: image segmentation, graph cuts, multiresolution analysis, local texture feature
