Abstract
This work extends a non-linear image enhancement scheme recently proposed [1]. We concentrate on parameter sensitivity in a global scheme, as well as motivate and discuss adaptive local parametrization in the enhancement algorithm. The enhancement scheme uses non-linear filtering to augment the frequency spectrum of a blurred input (creating new high-spatial frequencies). As a result of the enhancement, images are created with higher resolution than the sampling rate would allow. This property is highly valuable in application domains which require limited bandwidth to represent or transmit images, including the HDTV and video-phone markets.
