Embodiment Construction

[0035] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is a comprehensive technique of computer science that attempts to understand the nature of intelligence and produce a new kind of intelligent machine that can respond in a similar way to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-making.

[0036] Artificial intelligence technology is a comprehensive subject that involves a wide range of fields, including both hardware-level technology and software-level technology. Artificial intelligence basic technologies generally in...

Abstract

The invention discloses a face tracking method, device and equipment and a storage medium. The method comprises the following steps: performing face detection on a to-be-processed image frame of a video to obtain a face detection frame set corresponding to the to-be-processed image frame; for the ith target object, obtaining position information of a face detection box of the ith target object, and face attitude angle information and face feature information of the ith target object; determining whether a target historical object matched with the ith target object exists in the n historical objects or not according to the information and human face track information of the n historical objects detected in the video; and if so, updating the face track of the target historical object. According to the face tracking scheme based on the face feature information and the face attitude angle information provided by the invention, the interruption rate of face tracking can be effectively reduced by introducing the face attitude angle information, so that the face trajectory obtained by tracking is more complete and accurate.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular to a face tracking method, device, device, and storage medium. Background technique [0002] The purpose of face tracking is to track all the faces that appear in the video to obtain a complete face track. Face tracking algorithms play an important role in security monitoring, smart supermarkets, face filing and other fields. [0003] At present, the mainstream face tracking method is to first perform face detection on each frame of the video, and then correlate the face detection frames in the time domain through the positional relationship between the face detection frames in adjacent frames. In order to achieve the purpose of face tracking. [0004] However, the face tracking method provided by the above-mentioned related technologies has a relatively high error rate. Contents of the invention [0005] The embodiment of the present ap...
