Abstract: The present disclosure describes techniques for creating effects based on facial features. A mesh comprising a set of vertices based on detecting key points of at least one facial part may be created. A mask may be created based on rendering the mesh. A filter may be created by applying a function to a texture based on the mask. A portion of at least one image may be extracted based at least in part on the mask. The portion may correspond to the at least one facial part. An effect may be created on the extracted portion using the filter.

Abstract: Provided are a video processing method and apparatus, an electronic device, a storage medium and a program product. The method includes steps described below. A to-be-processed video is acquired, and a first face key point of a first target object in the to-be-processed video is recognized, where the first face key point corresponds to a mask key point in a three-dimensional human face mask effect; and the three-dimensional human face mask effect is added to video frames of the to-be-processed video to obtain a target video, where the mask key point in the three-dimensional human face mask effect moves with the corresponding first face key point.

A to-be-processed video is acquired, and a first face key point of a first target object in the to-be-processed video is recognized, where the first face key point corresponds to a mask key point in a three-dimensional human face mask special effect; and the three-dimensional human face mask special effect is added to video frames of the to-be-processed video to obtain a target video, where the mask key point in the three-dimensional human face mask special effect moves with the corresponding first face key point.
