METHODS AND APPARATUS FOR DECODING VIDEO SIGNALS USING MOTION COMPENSATED EXAMPLE-BASED SUPER-RESOLUTION FOR VIDEO COMPRESSION
Methods and apparatus are provided for decoding video signals using motion compensated example-based super-resolution for video compression. An apparatus includes an example-based super-resolution processor for receiving one or more high resolution replacement patch pictures generated from a static version of an input video sequence having motion, and performing example-based super-resolution to generate a reconstructed version of the static version of the input video sequence from the one or more high resolution replacement patch pictures. The reconstructed version of the static version of the input video sequence includes a plurality of pictures. The apparatus further includes an inverse image warper for receiving motion parameters for the input video sequence, and performing an inverse picture warping process based on the motion parameters to transform one or more of the plurality of pictures to generate a reconstruction of the input video sequence having the motion.
