摘要： Systems and techniques for processing sequences of video images involve receiving, on a computer, data corresponding to a sequence of video images detected by an image sensor. The received data is processed using a graphics processor to adjust one or more visual characteristics of the video images corresponding to the received data. The received data can include video data defining pixel values and ancillary data relating to settings on the image sensor. The video data can be processed in accordance with ancillary data to adjust the visual characteristics, which can include filtering the images, blending images, and/or other processing operations.

摘要： A temporal dithering manager uses temporal dithering to reduce contouring artifacts due to bit limiting. The temporal dithering manager truncates low order bits of an input signal, creates a temporal dither signal based on the truncated low order bits and applies the temporally created dither signal to the truncated signal. A temporal filtering manager applies a temporal filter to the truncated signal, thereby improving the quality of the truncated signal. The temporal dithering can be applied at a preprocessing stage, and the temporal filtering at a post-processing stage.

摘要： A post-processing manager provides reconstructed block based picture post-processing that is uncoupled from picture decoding by dividing a reconstructed image that was encoded using block based processing into non-overlapping blocks, creating a DC image by computing the DC value of each block, creating a zero mean image by subtracting the DC value of each block from the corresponding pixels of that block, filtering the DC image and adding the filtered DC image to the zero mean image. A weak filtering operation can be applied to reduce blocking artifacts, and a strong filtering operation can be applied to smooth luminance transitions.
