METHOD AND SYSTEM FOR PROVIDING SUPER-RESOLUTION OF QUANTIZED IMAGES AND VIDEO

摘要

An image-encoding system that is configured to generate an output stream based on an input image is provided that includes an encoder and a metadata extractor. The encoder is configured to encode a low-resolution image to generate a quantized, low-resolution image. The low-resolution image is generated based on the input image. The metadata extractor is configured to extract super-resolution (SR) metadata from the input image. The output stream comprises the quantized, low-resolution image and the SR metadata. An image-decoding system is configured to receive the output stream. The image-decoding system includes a decoder and an SR processor. The decoder is configured to decode the quantized, low-resolution image to generate a decoded image. The super-resolution processor is configured to perform super-resolution on the decoded image based on the SR metadata to generate a super-resolved image.
