Abstract: Techniques are disclosed involving contrast adjustment for images. For example, an input image is classified based on its pixel value characteristics, as expressed in an input brightness histogram. From such a classification, a target histogram distribution for a corresponding output image (i.e., a contrast-adjusted transformation of the input image) may be specified. With the target histogram of the output image specified, a transformation function may be derived that maps input image values to output image values. Moreover, transitions of such transformation functions may be smoothed. Such smoothing may provide advantages, such as a reduction in flickering associated with video data.

Abstract: An embodiment improves the operation of a H.264 and Joint Scalable Video Codec (e.g., JSVC/H.264 Amendment 3) video decoder by managing neighboring block data during the decoding process. An embodiment pre-computes neighboring block tables to efficiently locate the neighboring block data required to decode a current macroblock. In particular, the pre-computed most probable joint neighboring block tables disclosed herein handle both macroblock adaptive frame field (MBAFF) coding and non-MBAFF coding. An embodiment is further capable of managing variable block sizes. Other embodiments are described and claimed.
