1. A method for adaptive reduction of ringing artifacts in an input image including pixels of image information, comprising employing a processor for: selecting a pixel window including a set of pixels from the input image pixels; detecting areas of ringing artifacts in the pixel window based on a function of gradation level differences between one or more pixels therein, wherein the ringing artifact effect is based on the gradation level difference between the one or more pixels; processing the pixels in the detected areas to reduce the detected ringing artifacts in those areas; and generating an enhanced output image including the processed pixels with reduced ringing artifacts.
