Abstract

The invention discloses an expression driving method and a device, electronic equipment and a storage medium, and relates to the field of artificial intelligence, and the method can comprise the steps: carrying out the face key point detection of a driven person in a first image, and obtaining a first face key point sequence; for each second image obtained in sequence, the following processing iscarried out: performing face key point detection on a driving person in each second image to obtain a second face key point sequence; analyzing the second face key point sequence if the no-expressionframe image is not determined currently, and taking the second face key point sequence as a no-expression key point sequence if the second image is determined to be the no-expression frame image basedon an analysis result; and otherwise, obtaining a deviation value between the second face key point sequence and the expression-free key point sequence, and performing expression driving rendering onthe driven person based on the deviation value and the first face key point sequence. By applying the method of the invention, the flexibility, interactivity, accuracy and the like can be improved.

Description

technical field [0001] The present application relates to the field of computer applications, in particular to expression driving methods, devices, electronic equipment and storage media in the field of artificial intelligence. Background technique [0002] In applications such as short video, live video and film and television special effects, face special effect technologies can be used, such as beauty makeup, face changing, shaping and expression driving, etc. [0003] The current emoticon driving mainly adopts the following method: for the pictures uploaded by users containing the characters to be driven, map and drive according to several pre-set template expressions, which are poor in flexibility, interactivity and fun. Contents of the invention [0004] In view of this, the present application provides an expression driving method, device, electronic equipment and storage medium. [0005] An expression-driven method comprising: [0006] Performing face key point d...
