In this paper,a fast and practical implementation of Gabor filter is proposed.First,it gests the bandwidth parameter and center frequency of Gabor filter based on human vision and the size of texture image,constructing the multichannel Gabor filters and extracting the Gabor multitemporal and multidirectional energy features of image in the time and frequency domain and implementing nonlinear transform and Gauss low-pass filtering in the feature space.By adopting k-means clustering algorithm,the partition of the image is realized.The results of experiment ...
