Method of reducing document size for digital display |
摘要 |
A method of enhancing predefined features of a scanned image of a document page of reduced size for display includes subsampling the pixels of the scanned image to achieve a desired degree of reduction of the image size. The subsampled signals are passed through a filter to obtain gray scale values. A sharpening filter is applied to the subsampled pixels to enhance the predefined features of the image.
