A sharpening technique for digital images for presentation on a display is provided. In the technique, an image is modified in order to sharpen the features while at the same time suppress the noise. The image is first filtered resulting in at least two different channels of information. The channels can contain such information as texture information or edge and flat region information. Each channel is then further filtered in order to enhance the information stored in that channel. Finally, the channels are combined to result in a modified image with a different sharpness.
