CLASSIFIED ADAPTIVE ERROR RECOVERY METHOD AND APPARATUS

摘要

A method, apparatus, and article of manufacture for restoring a deteriorated signal (201) to an undeteriorated signal (213). A deteriorated signal (201) consists of a plurality of deteriorated and undeteriorated data points. For each deteriorated data point, a plurality of class types 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 (205). The undEteriorated signal (213) is generated by adaptive filtering the deteriorated input signal (201) in accordance with the input signal classification result (209). More than one classification method is used to crate the plurality of class types (219). Created classes may include a motion class (1809), an error class (1811), a spatial class (1807) or a spatial activity class.
