SYSTEM BASED ON REVERSIBLE METADATA EMBEDDING AND EXTRACTION OF IMAGE AND VIDEO

摘要

Disclosed is a system based on reversible metadata embedding and extraction of an image and a video. The system comprises a metadata embedding apparatus for embedding metadata in an image and a video and a metadata extraction apparatus for extracting the metadata from the image and the video, wherein the metadata embedding apparatus comprises a distortion compensation module for performing distortion compensation processing on a video signal, and the metadata extraction apparatus comprises a distortion compensation removal module for performing distortion compensation removal on the video signal. The processing process of an image and a video by the metadata embedding apparatus reversibly corresponds to the processing process of the image and the video by the metadata extraction apparatus. The system can perform reversible metadata embedding and extraction on an image and a video, and can perform distortion compensation and compensation removal on a video signal, respectively, when performing metadata embedding and extraction on the video, thereby reducing the visual distortion influence of metadata on a video signal and ensuring the visual quality of a video.
