Abstract: The present disclosure relates to encoding of video image using coding parameters, which are adapted based on events related to motion within the video image. Image content is captured by a standard image sensor and an event-triggered sensor, providing an event-signal indicating changes (e.g. amount and time-spatial location) of image intensity. Objects are detected within the video image, based on the event signal assessing motion of the object, and their textures extracted. The spatial-time coding parameters of the video image are determined based on the location and strength of the event signal, and the extent to which the detected objects moves.

Abstract: Embodiments of this application disclose example apparatuses, methods, and computer program products for extracting a feature from an image of a scene. One example apparatus comprises at least one processor and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to, in response to a feature extraction event, extract a feature from first image data representing a first image of a scene, wherein the feature extraction event is based on second image data representing a second image of the scene.

Abstract: This application provides a video processing method and apparatus. The method includes: adding, by a server, perception attribute information of an object and spatial location information of the object to a video bitstream or a video file, and encapsulating the video bitstream or the video file, where the perception attribute information is used to indicate a property presented when the object is perceived by a user; and obtaining, by a terminal device, the video bitstream or the video file that carries the perception attribute information of the object and the spatial location information of the object, and performing perception rendering on a perception attribute of the object based on behavior of the user, the perception attribute information of the object and the spatial location information of the object.
