Problems solved by technology

[0007] Different compilers have different calculation methods for floating-point data, and different calculation methods correspond to different benefits, so it is not possible to directly specify all compiler calculation methods
If the compiler at the encoding end uses the first method to operate on floating-point data, and the compiler at the decoding end uses the second method to perform operations on floating-point data, the results obtained at both ends are inconsistent, and the decoding end cannot work normally. decoding

Abstract

The present disclosure relates to the technical field of video coding, and relates to a method and apparatus for processing video frame data. The method comprises: converting the data type of a weight parameter in a pre-trained neural network into fixed-point type to obtain a converted weight parameter; converting the data type of video frame data to undergo target processing into fixed-point type to obtain converted video frame data; inputting the converted video frame data into a neural network loaded with the converted weight parameter to obtain video frame data after target processing. As such, the floating-point type data is converted into fixed-point type data, the decimal mark position of the fixed-point type data being fixed; results in an operation process do not need to be constrained, and the situation in which the same operation performed on the same data produces different results will not occur. In addition, operation results from encoding and decoding are consistent, and a decoding end may decode normally.

Description

technical field [0001] The present disclosure relates to the technical field of video coding and decoding, and in particular to a method and device for processing video frame data. Background technique [0002] In the process of compressing and encoding the video frame images, the video frame images need to be processed, such as filtering. Specifically, the original video frame image will be distorted, so the video frame image obtained during the decoding process is also a distorted video frame image. In order not to affect the use of the video frame image, it is necessary to filter the decoded distorted video frame image to obtain an undistorted video frame image. [0003] Studies have shown that neural networks can be used to filter distorted video frame images. [0004] The data to be calculated in the neural network is floating-point data, and the calculation result of the floating-point data is related to the calculation method. The number of decimal places of floati...
