A visual search method, a computer device, and a non-transitory computer readable storage medium are provided. An iimage frame is received. The location and the classification of the subject in the iimage frame are extracted. A detection block corresponding to the subject is generated. In subsequent image frames of the iimage frame, the subject is tracked on the basis of the location of the subject in the iimage frame. The detection block is adjusted on the basis of the tracking result. 1. A method for video searching , comprising:{'sup': 'th', 'receiving an iimage frame, i being a positive integer;'}{'sup': 'th', 'extracting a location and a classification of a subject in the iimage frame, and generating a detection block corresponding to the subject; and'}{'sup': th', 'th, 'in subsequent image frames of the iimage frame, tracking the subject according to the location of the subject in the iimage frame, and adjusting the detection block according to a tracking result.'}2. The method according to claim 1 , further comprising:{'sup': 'th', 'receiving an (i+M)image frame, M being a positive integer;'}{'sup': th', 'th, 'determining whether a subject in the (i+M)image frame changes relative to the subject in the iimage frame; and'}{'sup': th', 'th, 'in response to changing, regenerating a detection block according to the subject detected in the (i+M)image frame, and re-tracking the subject in the (i+M)image frame.'}3.
