摘要：A method, apparatus, and article of manufacture for restoring a deterioratedsignal to an undeteriorated signal. A deteriorated signal consists of a plurality of
deteriorated and undeteriorated data points. For each deteriorated data point, aplurality of class types including a motion vector class is created based uponcharacteristics of the area containing the deteriorated data point. The data point isclassified with respect to one of the plurality of class types and assigned a correspondinginput signal class. The undeteriorated signal is generated by adaptively filtering thedeteriorated input signal in accordance with the input signal classification result. Morethan one classification method is used to create the plurality of class types. Createdclasses may include a motion class, an error class, a spatial class, a spatial activity class, ora motion vector class.
