METHOD AND DEVICE FOR DETERMINING A SALIENCY VALUE OF A BLOCK OF A VIDEO FRAME BLOCKWISE PREDICTIVE ENCODED IN A DATA STREAM

摘要

The invention is made in the field of saliency determination for videos block-wise predictive encoded in a data stream. A method is proposed which comprises using processing means for determining coding costs of transformed residuals of blocks and using the determined coding costs for determining the saliency map. Coding costs of transformed block residuals depend on the vividness of content depicted in the blocks as well as on how-well the blocks are predicted and therefore are good indicators for saliency.
