Desktop video content analysis method

The invention relates to a desktop video content analysis method, which comprises the following steps of 1, sequentially taking each frame between the second frame and the last frame of all video frames collected within a particular period of a desktop image as a current frame, and respectively figuring out the image difference degree between a current frame and a previous frame; 2, according to the image difference degree between the current frame and the previous frame, classifying the current frame as a static frame, a small dynamic frame and a large dynamic frame, wherein the image difference degree of the static frame/the small dynamic frame/the large dynamic frame and the previous frame is gradually increased; 3, counting the proportions of the static frame, the small dynamic frame and the large dynamic frame within the particular period; 4, according to the statistical result of step 3, if the proportion of the static frame is larger than a first threshold value, judging the video to be the video of th
