Title
Adaptation of frames for GOP using NSEW affine translation for effective privacy protection mechanism
Abstract
AbstractThe group of pictures GOP plays a very important role in the privacy protection mechanism when data hiding is preferred through video transmission. GOP varies for every conventional video compression standards. The frame identification plays a key role in framing GOP. If frames are chosen adaptively using a matching criteria instead of precoded GOP, the further processing for video compression could be effectively done. The quality of the reconstructed video after compression can be improved subjectively if GOP is selected properly and thus, the embedded data can be retrieved without degradation. It is observed that B-frames in a GOP takes more computation time since it depends on the previous and next frame to be processed. So, NSEW affine translation technique is proposed to convert B-frames to either P-frames or I-frames depending on the matching criteria between frames. The result shows that the performance objective evaluation coincides with the subjective evaluation.
