Abstract: Painting-like artistic effects can be achieved from photographic images by filters that smooth out texture details，while preserving or enhancing edges and corners.A novel image filter is proposed in this paper to generate painting-like effects.By adaptively changing its bandwidth and shape to image features，this filter can simulate the size of brush and painting skills.A large variety of experimental results show that the output of the proposed operator is visually similar to a painting.The proposed operator is robust to degradations of the input image such as blurring and noise contamination.

Key words: adaptive filters, gradient structure tension, painting-like artistic effect
