MULTISCALE DIFFERENTIAL METHOD FOR DIGITAL IMAGE SHARPENING

We have proposed and tested a novel method for digital image sharpening. The method is based on multi-scale image analysis, calculation of differential responses of image brightness in different spatial scales, and the subsequent calculation of a restoration function, which sharpens the image by s...
