1. A video image processing device, comprising:
- a transmitter configured to transmit a residual bitstream via a communication link; and
processor circuitry communicatively coupled to the transmitter, the processor circuitry including;
a first census transform configured to generate one or more uncompressed census digit planes based on uncompressed video image data;
a second census transform configured to generate one or more decompressed census digit planes based on decompressed video image data, wherein the decompressed video image data was previously compressed;
a subtractor configured to receive the one or more uncompressed census digit planes and the one or more decompressed census digit planes, and to generate one or more residual census digit planes based on the one or more uncompressed census digit planes and the one or more decompressed census digit planes; and
a residual census digit generator configured to generate the residual bitstream based on the one or more residual census digit planes.

Abstract
An video image processing device configured to generate one or more census digit planes, and to generate one or more signature vectors based on the one or more census digit planes. The video image processing device can include one or more census transforms configured to perform one or more census transformations to generate the signature vector(s) based on the census digit plane(s).
