Embodiment Construction
[0054] Gait recognition is an emerging biometric technology that aims to identify people through their walking posture. Gait recognition has the advantages of non-contact long-distance and not easy to camouflage, and does not require high-definition image quality. Therefore, it can be widely used in security, public security, public transportation and other scenarios, and has great application potential.
[0055]Embodiments of the present invention provide video processing methods and related devices (video processing devices, video processing equipment, and storage media, etc.), which are applicable to various scenarios that require real-time or offline gait recognition technology services (such as intelligent video surveillance).
[0056] First introduce the core idea:
[0057] Gait recognition can be understood as a retrieval problem, given the video of the person to be queried (the object whose identity is to be identified) (can be called the first video or the video to be...

The embodiment of the invention provides a video processing method and a related device, and an image processing method and a related device. The video processing method comprises the steps of obtaining a to-be-processed video and generating a first gait energy diagram, wherein a video frame in the to-be-processed video comprises an identity to-be-identified object; obtaining a second gait energydiagram of the video of the object with the known identity; inputting the first gait energy diagram and the second gait energy diagram into a deep neural network to perform first gait recognition, wherein the first gait recognition comprises the steps of extracting respective identity information of the first gait energy diagram and the second gait energy diagram, and fused gait feature vectors ofthe first gait energy diagram and the second gait energy diagram; calculating similarity at least according to the extracted fused gait feature vector, wherein the identity information of the first gait energy diagram comprises an identifier and a gait feature vector of the first gait energy diagram, and the identity information of the second gait energy diagram comprises an identifier and a gaitfeature vector of the second gait energy diagram, wherein the fused gait feature vector is determined by the gait feature vectors of the first gait energy diagram and the second gait energy diagram.
Description
technical field [0001] The invention relates to the technical field of gait recognition, in particular to a video processing method, a video processing device, a video processing device and a storage medium, an image processing method, an image processing device, an image processing device and a storage medium. Background technique [0002] Gait recognition has application requirements in many scenarios. For example, there are many outdoor cameras in public places, but the cameras are generally far away from people, and the captured images or videos cannot be used for pedestrian recognition by face. However, gait recognition technology can perform pedestrian recognition based on human gait feature vectors, and does not have to be based on face recognition, nor does it require high-definition image quality. Therefore, gait recognition technology has become an important research direction. Contents of the invention [0003] Embodiments of the present invention provide a vid...
