Abstract

Peaking filters enhance the sharpness impression in video images, but are often complex and have some image-quality drawbacks. We compare two spatial peaking filters and investigate the one that combines a simple structure with good image quality. This simple structure makes our proposal a good candidate for software implementation on a programmable architecture. We evaluated the performance on a 32-bit1 and a new 64-bit multimedia processor
