ABSTRACT:
A super dithering method of color video quantization maintains the perceived video quality on a display with less bit depth of color than the input video. Super dithering relies on both the spatial and temporal properties of human visual system, wherein spatial dithering is applied to account for human eye's low pass spatial property, while temporal dithering is applied to achieve the quantization level of the spatial dithering.
