Document Type and Number:
WIPO Patent Application WO/2022/141895
Kind Code:
A1
Abstract:
Disclosed is a real-time training method for an expression database. The method comprises the following steps: S1, performing inputting in advance: before a performance, an actor inputting expression coordinate sequences of all expressions into an expression database in advance; S2, predetermining a range: analyzing, by means of big data, values of multidirectional tension sensors corresponding to the locations of all facial feature points of each expression to obtain a predetermined range; S3, collecting an expression in real time: the actor making different expressions during the performance, so as to generate a set of expression coordinate sequences consistent with the locations of the facial feature points in S1; S4: performing comparison and screening: performing comparison and screening on the value of the multidirectional tension sensor corresponding to the location of each facial feature point of the expression coordinate sequence; and S5, performing multi-sample training: discontinuously and accurately determining the predetermined range of the facial feature points by means of a large number of expression coordinate sequences. The motion state of a facial muscle is captured in real time during a performance to discontinuously update and accurately determine the predetermined range of each muscle for each expression of a specific actor, so as to achieve the aim of training a database.
