Abstract

The invention provides an image processing method and device, and relates to the field of computer images, and the method comprises the steps: obtaining the frame rate of an image window, wherein thedata frame of the image window is divided into at least one macro block; calculating and obtaining a frame rate change parameter according to the frame rate and a preset algorithm; detecting whether the macro blocks of the current data frame and the previous data frame are changed or not; if yes, judging whether a preset counter is larger than a first preset threshold value or not, wherein the counter is used for marking the times of continuously changing the macro block at the same position of different frames; and if the counter is greater than a first preset threshold value, setting the value of the counter as the frame rate change parameter. The problem that the video window identification result is influenced when the frame rate is relatively high can be solved.

Description

technical field [0001] The present disclosure relates to the field of computer images, in particular to an image processing method and device. Background technique [0002] In order to better integrate the advantages of H.264 in video coding, the Graphic Transaction Protocol (GTP) algorithm in the background art proposes an algorithm for identifying the playing window of a video image. [0003] The GTP video recognition method in the background art works well when the codec video frame rate is relatively low, but the rate will be relatively low for a higher frame rate. If the frame rate of the video is high, for example, the frame rate is 60, it is unavoidable that many frames will be the same as the previous frames, which will cause a certain frame without any change macroblocks to appear at intervals, thus affecting the recognition result of the video window.
