Classification: CPC H  G | IPC G  H

Claim 10:
11. An image processing apparatus comprising:
a demultiplexing processor configured to extract an input stream and parameter information by demultiplexing an input stream received from an encoding device;
an input stream buffer configured to store the extracted input stream;
a decoding processor configured to generate a restored frame by decoding the stored input stream;
a restored frame buffer configured to store the generated restored frame;
a machine learning image quality improvement processor configured to generate an output frame with an improved image quality by applying the extracted parameter information to the restored frame; and
an output frame buffer configured to store the generated output frame,
wherein the encoding device updates a parameter by machine learning based on an error between an input original frame and a restored frame restored from the original frame, the restored frame decoded at a local decoder and stored at the restored frame buffer, and transmits the parameter information corresponding to the updated parameter together with the input stream.
