Title:
METHOD AND DEVICE FOR DETERMINING PRIORITY ORDER OF VIDEO ENCODING AND DECODING ON BASIS OF CORRELATION COMPARISON
Document Type and Number:
WIPO Patent Application WO/2022/252567
Kind Code:
A1
Abstract:
Disclosed are a method and a device for determining the priority order of video encoding and decoding on the basis of correlation comparison, the method comprising: determining a corresponding correlation between each encoding block and each video analysis task; determining, on the basis of the correlation, a preferentially encoded encoding block; and encoding and/or transmitting the encoding block. The present invention determines, according to the requirements of a video analysis task, the correlation between sub-blocks and the video analysis task, determines encoding order on the basis of correlation, the encoding order and the transmission order of encoded data thereof preferentially processing important data according to the requirements of video analysis, performs video encoding, and converts the encoded data into a video code stream, which can ensure that the accuracy of video analysis results is within an acceptable range, and at the same time ensures that the data compression rate is optimal.
