Abstract:

Edge enhancement is effective to improve image quality. The optimum condition of edge enhancement has been studied. When the edge of object is enhanced, our visual system becomes easy to recognize the shape. But if the edge is enhanced too much, it is considered that the image become to feel unnatural. We found that the optimum edge enhancement depends on the categories of image. In this paper, the quality of image is improved by adjusting the strength and extent of edge enhancement. The images are captured under no-edge-enhancement and no-data-compressing conditions by digital still camera. The strength of the edge enhancement is modified by controlling the amount of Laplacian component and the extent of the edge enhancement is modified by the number of neighboring pixels processed. The image quality of various strength and extent is estimated by subjective evaluation. It is obtained that the edge enhancement is effective in human visual system when we concentrate on the shape of image.
