Abstract: Provided are an image processing method and apparatus, an electronic device, and a storage medium. The method includes determining a to-be-registered skeleton chain and a preset skeleton chain of a target part in a to-be-processed video frame; determining wrist or ankle state information of the to-be-registered wrist or ankle skeleton point according to first pose information of the to-be-registered wrist or ankle skeleton point and second pose information of the preset wrist or ankle skeleton point; determining finger or toe state information of the to-be-registered finger or toe skeleton point according to the wrist or ankle state information, third pose information of the to-be-registered finger or toe skeleton point, and fourth pose information of the preset finger or toe skeleton point; and displaying the target part in the to-be-processed video frame according to the wrist or ankle state information and the finger or toe state information.

Abstract: A method for controlling a virtual avatar comprises: dividing a virtual avatar into a plurality of skeleton chains, wherein each of the plurality of skeleton chains comprises a plurality of skeleton points; acquiring state information of at least one control point and initial state information of at least one skeleton point, wherein the state information comprises location information and orientation information; determining movement information of at least one skeleton point based on the state information of the at least one control point and/or the initial state information of the at least one skeleton point, wherein the movement information comprises translation information and/or rotation information; and controlling the at least one skeleton point whose movement information is determined to move according to the movement information.

Abstract: A method and apparatus for generating a directed distance field image, device, and storage medium. The method comprises: first, determining a valid line segment set corresponding to pixel points to be processed; then, determining internal and external position information of said pixel points on the basis of the valid line segment set of said pixel points; and finally, after the internal and external position information of each pixel point on an undirected distance field image of a target character is determined, generating a directed distance field image of the target character. The internal and external position information is determined on the basis of the valid line segment set corresponding to the pixel points to be processed, without needing to traverse all curve segments of the target character, such that efficiency of determining the internal and external position information of pixel points is improved, thereby improving the overall efficiency of generating the directed distance field image of the target character.
