1. An apparatus, comprising: a processor; a media processing node arranged to enhance sharpness of an input image using said processor, said media processing node comprising: a receiver to receive the input image; a wavelet decomposition module to perform wavelet decomposition of said input image to detect and modify edge information, wherein said wavelet decomposition module is to perform multiple levels of decomposition, with each level of decomposition having a detail component and an approximation component; and an edge enhancement module to receive said detail component as wavelet decomposition output from said wavelet decomposition module, and perform horizontal, vertical and diagonal enhancement on said detail component.
