Abstract :
In this paper, we present an unsharp masking-based approach for edge enhancing for TV application. The proposed scheme enhances the true details, limits the overshoot near sharp edges and attenuates the temporal artifacts which are visible in an image sequence. Simulations show that the processed sequence presents sharp edges which make it more pleasant to the human eye. Moreover, the amount of noise and nonhomogeneities in the sequence are clearly reduced
