【Abstract】 A new texture spectrum descriptor based on texture primitive equivalent is proposed The texture spectrum depicts the variational pattern of pixel gray scales in a pixel domain to describe image texture feature Image content is represented in terms of texture spectrum histogram Experimental results on a general image dataset show that the proposed texture descriptor takes less extraction time and provides higher image retrieval accuracy than Gabor approach in image retrieval更多还原
