Image processing apparatus and recording/reproducing apparatus |
摘要 |
<p>An image information processing apparatus for processing image information includes a total curvature calculating unit, mean curvature calculating unit, a logical product computing unit and a median filter. A total curvature at each pixel of the image information is calculated by the total curvature calculating unit. A mean curvature at each pixel of the image information is calculated by the mean curvature calculating unit. The logical product computing unit executes computation of a logical product of outputs from the total curvature calculating unit and the mean curvature calculating unit. An output from the logical product computing unit is filtered by the median filter. <IMAGE></p> |
