Abstract: A method for presenting a face in a video call includes: obtaining a key feature point of a facial expression of a user based on a face image of the user; driving a three-dimensional (3D) head image of the user by using the key feature point of the facial expression of the user, to obtain a target 3D avatar of the user, where the target 3D avatar of the user has an expression of the user; rotating the target 3D avatar based on a preset presentation angle, to obtain a target 3D avatar at the preset presentation angle; and transmitting the target 3D avatar at the preset presentation angle to a peer video call device. A user can see a 3D avatar that is of a user and that is at a preset presentation angle in real time.

Abstract: This application provides an automatic vehicle window cleaning method and apparatus, used to detect a foreign object on a vehicle window based on a value of a pixel in a vehicle window image, and perform automatic cleaning. The method includes: obtaining a vehicle window image; determining a dark channel image corresponding to a single frame of vehicle window image; further determining, based on a quantity of pixels whose gray values exceed a preset gray threshold in the dark channel image and/or definition of the dark channel image, that a first-type foreign object exists on a vehicle window; and/or determining, based on RGB values of pixels in i consecutive frames of vehicle window images, that a second-type foreign object exists on the vehicle window; and controlling a cleaning tool to remove a foreign object. The foreign object includes the first-type foreign object and/or the second-type foreign object.
