ABSTRACT:
In accordance with the teachings described herein, systems and methods are provided for enhancing the image quality of video. One or more filters may be used to filter a received video signal to generate a vertical filtered output, a horizontal filtered output and a diagonal filtered output. One or more amplification components may be used to apply separate gains to each of the vertical, horizontal and diagonal filtered outputs to generate a vertical enhancement signal, a horizontal enhancement signal and a diagonal enhancement signal. One or more summation components may be used to combine the vertical, horizontal and diagonal enhancement signals with the video signal to generate an enhanced video signal.
