摘要： Simulation of film grain in an image can occur by compressing a video image, then transmitting compressed video together with a message containing at least one parameter indicative of the original film grain, to a decoder, and restoring the original grainy appearance of images by having the decoder simulating film grain based on the content of the film grain message. To improve efficiency, one or more parameters of film grain information undergo scaling in accordance with a target pixel block size for pixel blocks in the image. Such scaling allows for the use of conventional circuitry for performing block-based operations in connection with the film grain simulation.

摘要： A method (200) for minimizing and optimizing a list of active reference pictures to be used for (forward or backward) inter coding of a current picture, or of a pixel region (e.g., video object) within the current picture. Setting the number of active reference pictures in a list equal to one (294) based upon one or more decisions related to the pixel data and movement between the current picture and one or more reference pictures. Otherwise, minimizing the number of active reference pictures (300) in the list based upon one or more other decisions related to the pixel data and movement between the current picture and one or more reference pictures. Minimizing the number of active reference pictures in a second reference picture list based upon the utilization of reference pictures in the first reference picture list. A video encoder (700) processes data representing a two-dimensional video image which has been produced by a conventional commercially available video camera. The video encoder is adapted to determine, select, and to minimize the number of active reference pictures to be used to inter code a current picture. The bit stream transmitted by the encoder (700) can be decoded by decoders of the related art.

摘要： A method for constructing a sequence of video pictures is disclosed. A region of a video picture that is supposed to be used as a predictor to construct a block corresponding to a second picture in a video sequence is ignored when an error correction technique is used to construct the predictor region (405). The invention applies information corresponding to a region from an alternative picture (410) in the video sequence as replacement for the predictor region. This replacement information is then used as the basis to predictively construct the block in accordance with a video decoding operation (415).
摘要翻译：公开了一种用于构建视频图像序列的方法。当使用错误校正技术构建预测器区域时，将忽略假想用作预测器来构建与视频序列中的第二图像相对应的块的视频图像的区域（405）。本发明将来自视频序列中的替代图像（410）的区域的信息应用于预测器区域的替换。然后将该替换信息用作根据视频解码操作预测构建块的基础（415）。
