Abstract
Improved image enhancement methods are disclosed which may be performed on conventional video processing systems. These methods operate in real time to improve the appearance of images as perceived by the human eye, and/or to render these images more suitable for computer analysis. A first preferred embodiment enhances color images without degrading the fidelity of the image. A second preferred embodiment enhances scanned gray-level document images by decreasing the blurring of the image and increasing the contrast between light and dark regions of the image.
