摘要： Methods and apparatus are provided for video encoding and decoding with learned transform and compressive sensing. An apparatus includes a video encoder for encoding an image block in a picture by determining from a training data set an adaptive transform for transforming a signal capable of representing the image block into zero coefficients and non-zero coefficients, reconstructing the image block in a pixel domain to obtain a reconstructed version of the image block by minimizing a number of the non-zero coefficients in a transform domain corresponding to the transform responsive to information of the signal and a prediction of the image block, and incorporating the reconstructed version of the image block into a coding mode that is absent from any video coding standards and video coding recommendations.

摘要： 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.
