Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0032] For human expressions, it often lasts for a period of time from the appearance of an expression to its disappearance. During this process, the muscles of the face are continuously changing. It is reflected in the video, that is, the faces in the pictures of consecutive frames of a video have different characteristics, that is, both tempor...

Abstract

The embodiment of the invention discloses an expression recognition method, device and equipment for a video. The method comprises the steps: extracting a corresponding image sequence from any video comprising a face; extracting a face image in the video through face recognition, and carrying out a corresponding alignment operation as the input; carrying out the feature extraction comprising spatial features and time features through a pre-trained 3D convolution neural network, and generating a feature vector. The method integrates the prediction of the time-space domain of an image sequence,and achieves the more accurate expression recognition according to the feature vector.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a video expression recognition method, device and equipment. Background technique [0002] With the development of technology, facial expression recognition for videos needs to be used in more and more life scenes. [0003] In the current technology, most of the methods of extracting various features of the face in the video (such as geometric features, statistical features, etc.) are used to perform positioning and statistical methods for expression recognition, which loses a lot of recognition and classification information, and the recognition results are accurate. lower degree. [0004] Based on this, a more accurate facial expression recognition scheme for videos is needed. Contents of the invention [0005] The embodiments of this specification provide a video expression recognition method, device, and equipment to solve the following problem: to provide a mo...
