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.

Abstract: Example implementations include a method, apparatus and computer-readable medium for decentralized procedural digital asset creation, comprising receiving a first request to create a digital asset from an application executing an augmented reality effect on a computing device, wherein the first request includes an identifier associated with a user of the application. The implementations further include generating the digital asset and metadata of the digital asset, wherein the metadata includes information about characteristics of the digital asset and ownership of the digital asset by the user. Additionally, the implementations further include storing the metadata on a blockchain. Additionally, the implementations further include receiving a second request to access the digital asset from the application. Additionally, the implementations further include transmitting, to the application for rendering, the metadata stored on the blockchain in response to validating the identifier associated with the user in the second request.

Abstract: The present application provides a special effect processing method and apparatus. The method includes: generating an audio signal in response to a touch operation of a user in a process of playing a video; segmenting the audio signal into multiple audio frames; performing, according to attributes of the audio frames, special effect processing on a picture which is currently played in the video.
