20130251271 | Method for Low Bit-Depth Image Generation - The present invention provides method to reduce the computation cost of generating low bit-depth image. One embodiment of the invention first truncates one or more least significant bits of image pixels, then filters the LSB-truncated-pixel image, and finally the truncated-pixel image and filtered image are compared to construct a low bit-depth image. To compute the filtered pixel value, one embodiment of the invention computes some intermediate values, saves and uses the said intermediate values for computing the next pixel. One embodiment of the present invention provides method of generation the filtered image by assigning a plurality of filtered image pixels with the same value. | 09-26-2013 |
