摘要： A method and apparatus for estimating the motion of an image region (the “center” region) from a source video frame to a target video frame. The motion estimation is locally constrained in that the estimated motion of the “center region” is affected by the estimated motion of neighboring regions. Advantageously, this may reduce common motion matching problems such as false and ambiguous matches. In one embodiment, the locally-constrained motion estimation may be implemented by biasing an error map of the center region using error maps of the neighboring regions.

摘要： Using image segmentation in video compression brings about a limitation in video quality when a segment moves in position from frame to frame. The limitation arises because color contributions (bleeding or blurring) naturally occur between neighboring segments. The above-identified problem is overcome by providing solutions to compensate for color contributions between neighboring segments. In accordance with one embodiment, a method and apparatus de-blurs an image segment. De-blurring involves removing from the segment approximate color contributions from neighboring segments. This results in a segment that is approximately independent of color contributions from neighboring segments. In accordance with another embodiment, a method and apparatus re-blurs an image segment. Re-blurring involves adding to the segment approximate color contributions from a new arrangement of neighboring segments. This results in more realistic rendering of the segment, as it is located in the new arrangement.

摘要： A spread spectrum system having data transmitted in a spread spectrum signal. Periodic and quasi-periodic signals which act as interference in the spectrum of interest is effectively filtered out by using a linear predictive coding filter. The LPC filter takes a digitized received spread spectrum signal and generates a set of predictive coefficients and a set of error coefficients. The predictive coefficients represent the interfering periodic and/or quasi-periodic signals. As such, the set of predictive coefficients are discarded. The remaining error coefficients represent what is left over and thereby contains the useful transmitted data found within the spread spectrum signal. The error coefficients are used by the signal processing block to extract the transmitted data.

摘要： The present invention provides efficient and effective quality of service for information that is time sensitive (e.g., real time data). An intermediate network communication system and method (e.g., a router) of the present invention performs cut through switching to reduce latency problems for time sensitive information. In one embodiment of the present invention, communication packet header information is encoded with a time sensitive identifier that identifies the information as time sensitive. In one exemplary transfer control protocol/internet protocol TCP/IP implementation of the present invention, time sensitive indication is provided in the link layer information. In one embodiment of the present invention, time sensitive information is dropped if the intermediate network device can not communicate the information within specified timing constraints. In one embodiment of the present invention time sensitive information is cut through routed on a virtual channel and pre-empts non time sensitive information. In one embodiment a communication path probe is cut through routed via intermediate network devices to establish a communication path before other information is communicated from a originating source to a final destination. In one embodiment the present invention leverages previously collected information to establish a communication path. In one embodiment the present invention, an intermediate network device establishes a second communication link if a first communication link is unavailable.

摘要： The present invention pertains to an apparatus for and method of mapping texture memory to a texture cache such that cache contention is minimized. Significantly, in one embodiment of the present invention, addresses of the texture memory are mapped to entries of the texture cache according to a predetermined hashing scheme. According to the one embodiment, texture memory is addressed as a virtually contiguous address space by a multi-dimensional index. The multi-dimensional index is further partitioned into a low order bit field and a high order bit field. Low order bits of the multi-dimensional index are directly mapped to low order bits of the cache address. High order bits of the multi-dimensional index are mapped to high order bits of the cache address according to a predetermined address-hashing scheme. Particularly, in one embodiment, high order bits of the multi-dimensional index are selectively “exclusive-or-ed” to generate corresponding addresses of the texture cache.
