Abstract
Abstract Apparatus and methods are provided for analyzing and enhancing a received data signal representing one or more views of a captured scene. The received data signal includes a plurality of data points. Each view includes a plurality of image points. Ones of the plurality of data points are representative of ones of the plurality of image points. A plurality of data sets are identified wherein each one of the data sets includes ones of the plurality of data points. Ones of the identified data sets are compared with one or more standard values and, in response thereto, are enhanced selectively to generate an output signal representing a processed 3-D scene estimate.
