Abstract: This application provides a chip, a dynamic vision sensor, and a method for outputting pixel information. The chip includes a pixel array and a processing circuit, and each pixel row in the pixel array includes at least two pixel groups. In the processing circuit, based on a change of a light intensity value of at least one pixel in a first pixel group, a first signal including row location information of the first pixel group in the pixel array is generated, and a second signal including column location information of a pixel row in which the first pixel group is located is generated. The first signal and the second signal are sent to a pixel output circuit, to enable the pixel output circuit to accurately output location information of the first pixel group whose light intensity value changes in the pixel array.

Abstract: In a model training method, a computing device generates an initial virtual human speaking video based on an audio data set and a person speaking video. The computing device trains a lip synchronization parameter generation model based on the audio data set and a lip synchronization training parameter used as a model training label. The computing device then uses the lip synchronization parameter generation model to generate a lip synchronization parameter based on input audio, and the lip synchronization parameter is used to drive a virtual human to speak. The computing device expands a data amount of the lip synchronization training parameter by using the initial virtual human speaking video.

Abstract: This application provides a pixel of an image sensor and an image sensor. The pixel may include an optical-to-electrical conversion circuit and a composite measurement circuit. The optical-to-electrical conversion circuit may be configured to generate a first current based on incident light that is incident on the pixel. The composite measurement circuit is coupled to the optical-to-electrical conversion circuit. The pixel may have a first operating mode and a second operating mode. The composite measurement circuit may generate a first pulse signal based on the first current when the pixel operates in the first operating mode, where the first pulse signal represents the intensity information of the incident light. When the pixel operates in the second operating mode, the pixel receives a plurality of sampling signals, and generates a plurality of second pulse signals based on the first current and the plurality of sampling signals.

Abstract: A rendering model training method and apparatus are provided. A related video rendering method and apparatus, a device, and a storage medium are also provided. The rendering model training method includes: obtaining a first video including a face of a target object; mapping a facial action of the target object in the first video based on a three-dimensional face model, to obtain a second video including a three-dimensional face; and training an initial rendering model by using the second video as an input of the initial rendering model and using the first video as supervision of an output of the initial rendering model, to obtain a target rendering model. The second video generated based on the three-dimensional face model is used as a sample for training the rendering model.
