The invention discloses a detection method of an anchor shot in a news video, which comprises the following steps: carrying out shot segmentation detection for the news video; removing the non-key regions of an image and extracting spatio-temporal slices in two diagonal directions; segmenting the spatio-temporal slices along the time direction and in the direction vertical to the time direction to obtain a plurality of windows; selecting a first part and a last part in a window corresponding to each shot of each part; extracting characteristic vectors of selected window images; clustering thecharacteristic vectors through a serial clustering method, and extracting the preliminary anchor shots; utilizing image movement characteristics to further screen the obtained preliminary anchor shots; and fusing the results of the screened parts to obtain the final news anchor shot. The invention has the advantages of high detection accuracy and low computational complexity for the anchor shots in various news videos, effectively solves the problems that the omission factor is higher when an anchor is not in the middle of a screen and under the condition of a dynamic studio background in theprior art.
