Methods and apparatus are provided for video encoders and decoders using compressive sensing. The encoding method encodes an image block in a picture by generating a measurement vector for the image block, encoding the measurement vector, and reconstructing the image block by minimizing a signal sparsity of the image block responsive to the encoded measurement vector, the measurement vector including transform coefficients relating to the image block. A corresponding decoding method decodes an image block for a picture by receiving a measurement vector for the image block, decoding the measurement vector, and reconstructing the image block by minimizing a signal sparsity of the image block responsive to the decoded measurement vector, wherein the measurement vector includes transform coefficients relating to the image block. |
