    Abstract: The application provides a virtual object image display method and apparatus, an electronic device and a storage medium, relates to the field of artificial intelligence, in particular to the field of computer vision and deep learning, and may be applied to virtual object dialogue scenarios. The specific implementation scheme includes: segmenting acquired voice to obtain voice segments; predicting lip shape sequence information for the voice segments; searching for a corresponding lip shape image sequence based on the lip shape sequence information; performing lip fusion between the lip shape image sequence and a virtual object baseplate to obtain a virtual object image; displaying the virtual object image. The application improves ability to obtain virtual object image.

    Abstract: The present application discloses a method and apparatus for determining the shape of the lips of a virtual character, a device and a computer storage medium, and relates to an artificial intelligence technology, and particularly to computer vision and deep learning technologies. An implementation includes: determining a phoneme sequence corresponding to a voice, the phoneme sequence including a phoneme corresponding to each time point; determining lip-shape key point information corresponding to each phoneme in the phoneme sequence; searching a pre-established lip shape library according to each piece of determined lip-shape key point information, so as to obtain a lip shape image of each phoneme; and corresponding the searched lip shape image of each phoneme with each time point to obtain a lip-shape image sequence corresponding to the voice. With the present application, the voice may be synchronized with the shapes of the lips in the images.

    Abstract: A method, an electronic device and a storage medium for expression driving are disclosed. The method may include: performing facial key point detection on a driven character in a first image to obtain a first facial key point sequence; performing the following processing for each second image of a plurality of second images obtained successively: performing facial key point detection on a driving character in the second image to obtain a second facial key point sequence; obtaining a difference between the second facial key point sequence and an expressionless key point sequence which has been determined previously according to an analysis on the second facial key point sequence for a previous second image, and performing expression drive rendering on the driven character based on the difference and the first facial key point sequence. The technical solution may enhance flexibility, interactivity, accuracy etc.
