Abstract:

Edge enhancement is effective to improve image quality. The optimum condition of edge enhancement has been studied on the histogram of objects of the image. When the edge of object is enhanced, our visual system becomes easy to recognize the shape and have sharp feeling. But if the edge is enhanced too much, we feel the image unnatural. It has been studied that the optimum edge enhancement depends on the histogram of image. In this study, the optimum conditions dependence on the factors of edge strength and color effect is investigated. The optimum edge enhancement condition will be varied by the sharpness of the edge of object. The image objects of various levels of edge sharpness are processed by edge enhancement and the processed images are estimated by subjective evaluation. The optimum edge enhancement condition is obtained.
