Abstract: A method for coding includes: obtaining original point cloud data; creating an adaptive prediction list of the depth information of the point cloud; and predictively coding the depth information of the point cloud based on the adaptive prediction list, to obtain codestream information. According to the present invention, an adaptively updated prediction list of the depth information is created, and an optimal prediction mode is selected from the list to predict the depth information of the point cloud.

Abstract: A voice awakening method and apparatus, a device, and a medium are provided. The voice awakening method includes: collecting a voice signal by using a microphone array (S201); separately performing denoising processing on the voice signal by using N beamforming denoising algorithms to obtain N denoising signals, where each beamforming denoising algorithm corresponds to one of N areas, different beamforming denoising algorithms correspond to different areas, a union set of the N areas covers a signal collection area of the microphone array, and N is a positive integer greater than 1 (S202); and performing voice awakening by using an awakening engine based on at least one of the N denoising signals (S203). The method can maximize denoising performance of the denoising algorithms and can cancel an echo outside a beam to enhance echo cancellation performance, featuring a relatively high awakening rate and recognition rate. In addition, the method is easy to implement and popularize.
