Abstract: This paper proposes an algorithm based on the similarity measurement of the spectral histograms for texture segmentation.In the texture segmentation algorithm，the seed selection is not needed.First of all，to acquire the texture features，using the algorithm of filter selection，then based on a local spatial/frequency representation，spectral histogram is employed as feature statistic for texture segmentation.For another，the initial result is derived by using x²-statistic to measure the similarity between two spectral histograms.The final segmentation result is obtained by applying the method of morphology skeletonization to locate the region boundaries.Experimental results demonstrate that the proposed method is effective.
