Abstract:
1. A method for image decoding, comprising the steps of: (A) receiving from a medium (i) an encoded signal, (ii) encoding statistics embedded in said encoded signal and (iii) a pre-processing signal carrying pre-processing information, wherein (a) said encoding statistics are created by an encoder in encoding an intermediate input signal to create said encoded signal and (b) said pre-processing information is created by a pre-processor in converting an image input signal into said intermediate input signal; (B) generating an intermediate output signal by decoding said encoded signal in a decoder circuit, wherein said decoding is performed in response to said pre-processing information; (C) generating a statistics signal in said decoding of said encoded signal, wherein said statistics signal (i) carries said encoding statistics created by said encoder and (ii) is separate from said intermediate output signal; and (D) generating an image output signal from a post-processor circuit by processing said intermediate output signal in response to both said statistics signal and said pre-processing signal, wherein said image output signal carries at least one image.
