CLASSIFIED ADAPTIVE ERROR RECOVERY METHOD AND APPARATUS

摘要

A method, apparatus, and article of manufacture for restoring a deteriorated signal to an undeteriorated signal. A deteriorated signal (101) consists of a plurality of deteriorated and undeteriorated data points. The data signal is preprocessed (280) into a motion compensated signal. For each deteriorated data point, a plurality of class types (205) including a motion vector class is created based upon characteristics of the area containing the deteriorated data point. A motion vector is detected and data is shifted (207) according to the detected motion vector. The data point is classified (211) 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 (209) 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.
