FILTER FOR ADAPTIVE NOISE REDUCTION AND SHARPNESS ENHANCEMENT FOR ELECTRONICALLY DISPLAYED PICTURES

Electronic images that are degraded by noise and data reduction, such as MPEG encoding, display artifacts in the reproduced image, such as ringing ("ripples") and blocks ("huge pixels"), and noise in the image may be apparent as graininess. By performing image analysis, both on a...

description	Electronic images that are degraded by noise and data reduction, such as MPEG encoding, display artifacts in the reproduced image, such as ringing ("ripples") and blocks ("huge pixels"), and noise in the image may be apparent as graininess. By performing image analysis, both on a frame-by-frame and pixel-by-pixel basis it is possible to identify and separate edges in the image, ringing artifacts and the boundaries between block transitions. By applying noise reduction according to the analysis, followed by sharpness enhancement, it is possible to clean up the image for further utilization.
