The invention relates to a multi-target detection algorithm and device for a yellow-related and violent-related video. The algorithm comprises the following steps: acquiring continuous multi-frame picture data in a video file; on the basis of continuous multi-frame picture data, obtaining each piece of figure form data in single-frame picture data; the method comprises the steps of obtaining a risk value of the single-frame picture data based on comparison of figure form data and dangerous feature data, carrying out further feature extraction and recognition on a picture based on the risk value of the single-frame picture data, judging whether the picture data to be judged have the content of the yellow-related and violent, and carrying out circular processing on the whole algorithm to obtain the risk value of the yellow-related and violent of the single-frame picture data. Outputting a judgment result of the video until a certain picture data has the content related to the yellow and the violence or all pict
