METHOD AND SYSTEM FOR GENERATING METADATA RELATED TO Original FRAMES

Methods and systems are provided for generating metadata related to an original frame. The method includes: selecting an input frame from among a captured original frame, a plurality of frames obtained by processing the captured original frame, and a scaled original frame; selecting the identified salient region in the output frame based on an error between the region of the input frame and a respective reconstruction of the region of the input frame according to the identified salient region in the output frame constructed based on the captured original frame; obtaining a plurality of reconstructed frames reconstructed according to the plurality of blocks of each identified salient region, the plurality of reconstructed frames corresponding to the plurality of regions of the input frame; and generating metadata for reconstructing the captured original frame by encoding a plurality of errors between the plurality of reconstructed frames and the respective plurality of regions of the input frame and a reconstr
