摘要： The disclosed invention is a enhancement to the Video Encoder component of the MPEG standard to improve both the efficiency and quality of the video presentation at the display device. The inventions described below pertain to the enhancement of video compression technology. In general, they are compatible with MPEG video standards (as in current art), but represent novel enhancements thereof. The above inventions apply to several transmission media and networks including cable, DSL, wireless, satellite and IP networks. Another category of invention in this disclosure enhances networking performance by recognizing that the transmitted information is video, rather than data. This invention can be scaled to other classes of multimedia data such as speech or audio or images.

摘要： Blocks of video images are characterized as being part of either scene foreground or background for encoding. The foreground/background segmentation analysis involves a pixel level and a block level. During the pixel level, interframe differences corresponding to each original image are thresholded to generate an initial pixel-level mask. A first morphological filter is applied to the initial pixel-level mask to generate a filtered pixel-level mask. During the block level, the filtered pixel-level mask is thresholded to generate an initial block-level mask. A second morphological filter is preferably applied to the initial block-level mask to generate a filtered block-level mask. Each element of the filtered block-level mask indicates whether the corresponding block of the original image is part of the foreground or background. In a preferred embodiment, both morphological filters filter out isolated mask elements.
摘要翻译：视频图像块被表征为场景前景或编码背景的一部分。前景/背景分割分析涉及像素级和块级。在像素级期间，对应于每个原始图像的帧间差异被阈值化以产生初始像素级掩码。将第一形态滤波器应用于初始像素级掩模以产生滤波像素级掩码。在块级别期间，将经滤波的像素级掩码阈值化以生成初始块级掩码。优选地，将第二形态滤波器应用于初始块级掩码以产生经滤波的块级掩码。滤波块级掩码的每个元素指示原始图像的相应块是前景还是背景的一部分。在优选实施例中，两个形态滤波器滤除隔离的掩模元件。

摘要： A background region of the current image is compared to a reference region to characterize the gain associated with the current image. The values of the unsaturated background pixels of the current image are then adjusted to correct for the characterized gain before encoding the current image. In a preferred embodiment, the reference region is generated based on the previous n frames in the video sequence.
