Problems solved by technology
Therefore, while ensuring the effect of image super-resolution processing, the processor needs to perform a large number of convolution operations to run the super-resolution convolutional neural network, and the power consumption also increases with the increase in the calculation amount of the processor.
In addition, because the super-resolution processing of video can be disassembled into the super-resolution processing of each frame of image in the video, and the amount of pixel data of each frame of image in the video is also large, so the processor performs super-resolution on each frame of image High-rate processing will take a long time due to the large amount of data, so the super-resolution processing delay of any two frames of images in the video will also increase with the increase in the amount of calculation of the processor

The embodiment of the present application discloses a video super-resolution processing method and device. The method includes: obtaining the coding information of any coding block in the video stream, and determining the inter-frame prediction flag of any coding block according to the coding information. prediction mode, and according to the inter-frame prediction mode of any coding block and the pixel information of the matching coding block identified by the matching coding block index included in the coding information, the super-resolution pixel block of any coding block is determined, and the video stream belongs to The super-resolution pixel blocks of each coding block of the same image frame are spliced to obtain a super-resolution image, and the super-resolution image is used to generate a super-resolution video. By adopting the embodiment of the present application, while ensuring the super-resolution processing effect of a single frame image in the video, power consumption can be reduced, and the super-resolution processing delay of any two frames of images in the video can be reduced.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a video super-resolution processing method and device. Background technique [0002] Generally, the definition of video (or image) is determined by the resolution of the image, low-resolution (low-resolution, LR) means that the definition of the image is low, high-resolution (high-resolution, HR) means that the image is Higher definition. To obtain high-resolution video sources, the most direct way is to use high-resolution image sensors, but high-resolution video sources are extremely scarce in daily life, and the storage and transmission of high-resolution video sources will give Current transmission networks pose a heavy burden. Therefore, people have proposed super-resolution (SR) technology, which can restore high-resolution video on the basis of existing low-resolution video sources. Super-resolution technology is to improve the resolution of the original ima...
