However, with the increase in the number of people in the entertainment industry and film and television works, "face collisions" often occur between actors. Because some actors have very similar looks and similar styles, recognition often occurs when identifying characters. Misrecognition, which is more common for long-range shots, resulting in less accurate person recognition

The present application discloses a cast-based character recognition method, device, equipment and medium. The method includes: identifying a facial image of a person appearing in the video, determining the identity information of the person based on the facial image, and obtaining a first identity information set, wherein the first identity set includes at least one identity information; The character name list in the cast list of the above video is used to filter the first set of identity information to obtain the second set of identity information. Through this method, character head recognition and text recognition can be combined, and the information of the actor list can be used to assist in the identification of character identities, so that actors with similar looks can be distinguished, and the accuracy of recognition can be improved in the case of fuzzy characters in the long-range shot. Reduce unrecognized and misidentified situations.
Description
technical field [0001] The present application relates to the field of video image processing, in particular to a character recognition method, device, device and medium based on cast members. Background technique [0002] When identifying characters in film and television works, the usual practice is to compare the head portraits of the characters appearing in the video frame with the photos in the sample set of the database, so as to identify the identity of the characters and mark the characters. However, with the increase in the number of people in the entertainment industry and film and television works, "face collisions" often occur between actors. Because some actors have very similar looks and similar styles, recognition often occurs when identifying characters. Misrecognition, for long-range shots, misrecognition is more common, resulting in a reduction in the accuracy of character recognition. Contents of the invention [0003] It is an object of the present app...
