摘要： The present invention provides a system and method for explicitly transmitting a block attribute in the data of a block. In one embodiment, a current block of data is randomized in accordance with an ID value from the current block and from at least one temporally adjacent block of data. The ID of the current block is selected such that when combined with determined bits of the data results in the value of the block attribute. During a decoding process, the block attribute is retrieved by accessing the determined bits of the data. In one embodiment, the data is then decoded by generating possible candidate decodings and evaluating the candidate decodings based upon confidence metrics.

摘要： The present invention provides a method for comprising data by determining a central value that is greater than the minimum value and less than the maximum value of the range of data. In one embodiment, the central value is chosen to be a value that substantially reduces a decoding error in the event that the range of values is subsequently estimated. In one embodiment, the central value is the value that minimizes the expected mean square error during reconstruction when there is an error. In one embodiment, the maximum and minimum values represent intensity data for pixels of an image. In another embodiment, the compression process is Adaptive Dynamic Range Coding, and the central value is a value within the dynamic range, excluding the maximum and minimum values.

摘要： A method, apparatus, and article of manufacture for restoring a deteriorated signal to an undeteriorated signal. A deteriorated signal consists of a plurality of deteriorated and undeteriorated data points. For each deteriorated data point, a plurality of class types including a motion vector class is created based upon characteristics of the area containing the deteriorated data point. The data point is classified with respect to one of the plurality of class types and assigned a corresponding input signal class. The undeteriorated signal is generated by adaptively filtering the deteriorated input signal in accordance with the input signal classification result. More than one classification method is used to create the plurality of class types. Created classes may include a motion class, an error class, a spatial class, a spatial activity class, or a motion vector class.
