Abstract

The invention provides a video area determination method and device, relates to the technical field of image processing, and aims to solve the problems that video area detection is large in detectionerror and low in efficiency. According to the specific technical scheme, the method includes: acquiring a to-be-detected image frame and a previous image frame of the to-be-detected image frame; acquiring video boundary information when the previous image frame contains video data; comparing an initial boundary area on the to-be-detected image frame with a reference boundary area, wherein the reference boundary area is the video boundary area of the previous image frame, and the initial boundary area is an area, identical with the reference boundary area in position, on the to-be-detected image frame; determining the area identical with the reference video area in position as the video area of the to-be-detected image frame when the proportion of the identical content area of the initial boundary area and the reference boundary area is larger than or equal to a first threshold, wherein the reference video area is the video area of the previous image frame. The video area determinationmethod and device is applicable to video area determination.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to a method and device for determining a video area. Background technique [0002] With the development of image processing technology, in many application scenarios, it is necessary to identify the video area of ​​the display interface, which can improve the efficiency of data processing. In the related technology, the pixels of each image frame in the data stream are compared with the pixels of the previous image frame, and the video area is determined according to whether the pixels are the same. However, if the content of the video image frame changes slightly, a large error will occur in the detection of the video region. Moreover, the detection of the video region in this way requires a large amount of computation and low efficiency. Contents of the invention [0003] Embodiments of the present disclosure provide a method and device for determining a v...
