Abstract: This paper improves the previous coarseness algorithm on the selection of neighborhood sizes and the calculation of neighborhood average differences, and the improved coarseness algorithm is presented. Experiments show that the improved coarseness has higher texture discriminability and better circumrotation invariance, and that the image retrieval result based on the improved coarseness is superior to that based on the previous coarseness.
