Abstract: An image rendering method and a related device thereof are disclosed. The method includes: performing ray tracing based on rendering information of a reflecting object, and storing an obtained image of a reflection in the reflecting object in a first frame buffer, where the first frame buffer is used for storing an image that does not need to be displayed temporarily; performing rasterization separately based on the rendering information of the reflecting object and rendering information of a reflected object, and storing an obtained image of the reflecting object and an obtained image of the reflected object in a second frame buffer, where the second frame buffer is used for storing an image to be displayed; and obtaining, from the first frame buffer, the image of the reflection in the reflecting object, and storing the image of the reflection in the reflecting object in the second frame buffer.

Abstract: This disclosure provides an image sensor, an imaging module, an image capturing device, and an image processing method. The image sensor includes: an optical signal obtaining module and a communication interface. The optical signal obtaining module may be configured to obtain an optical signal of a red-green-blue spectral band and an optical signal of a hyperspectral band from a received optical signal, and convert the optical signal of the red-green-blue spectral band and the optical signal of the hyperspectral band into an electrical signal. The optical signal obtaining module includes a first optical structure corresponding to the red-green-blue spectral band and a second optical structure corresponding to the hyperspectral band. The first optical structure is configured to obtain the optical signal of the red-green-blue spectral band from the optical signal, and the second optical structure is configured to obtain the optical signal of the hyperspectral band from the optical signal.

Abstract: Embodiments of the present disclosure provide a headset control method, a headset, a headset control apparatus, and a related storage medium. The method includes: collecting environment information, and determining key sound detection sensitivity based on the environment information; performing key sound detection in the environment information based on the key sound detection sensitivity; and if a key sound exists in the environment information, adjusting the headset to a hear through mode, or playing the key sound. The headset collects the environment information, determines the key sound detection sensitivity based on the environment information, and performs key sound detection in the environment information based on the key sound detection sensitivity. If the key sound exists, the headset is adjusted to the hear through mode, or the key sound is played. In this solution, the key sound detection sensitivity corresponding to the environment information is determined based on the environment information, to perform key sound detection.

Abstract: This application provides a hearing monitoring method and apparatus. The method includes: obtaining ear overuse information of a user, where the ear overuse information includes accumulated duration and/or accumulated times of overuse of ears of the user; and generating prompt information or a control instruction based on the ear overuse information. In this solution, because accumulated information is obtained, impact of a misoperation of the user can be excluded, and continued overuse of ears is also fully detected. Therefore, an unnecessary or missed reminder is avoided, thereby achieving more accurate hearing monitoring effect.

Abstract: A device receives a computation graph and transforms the computation graph into a dataflow graph comprising recursive subgraphs. Each recursive subgraph comprises a tuple of another recursive subgraph and an operator node, or an empty graph. The device determines a number of partitioning recursions based on a number of parallel computing devices. For each partitioning recursion, the device determines costs corresponding to operator nodes, determines a processing order of the recursive subgraphs, and processes the recursive subgraphs. To process a recursive subgraph, the device selects a partitioning axis for tensors associated with an operator node of the recursive subgraph. The device outputs a partitioning scheme comprising partitioning axes for each tensor associated with the operator nodes.

Abstract: Example data generation methods and apparatuses are provided. One example method includes obtaining, by a data generation apparatus, spatial object information. The data generation apparatus can then generate content information for describing the spatial object. The data generation apparatus can then generate azimuth information based on the spatial object information, where the azimuth information indicates an azimuth of a spatial object relative to the data generation apparatus. The data generation apparatus can then generate, based on the azimuth information and the content information, spatial sound data for playing a spatial sound, where a position of a sound source of the spatial sound corresponds to the azimuth information.

Abstract: This application provides a memory allocation method. The method includes: obtaining a computation graph corresponding to a neural network; sequentially allocating memory space to M pieces of tensor data based on a sorting result of the M pieces of tensor data, where if at least a part of the allocated memory space can be reused for one of the M pieces of tensor data, the at least a part of the memory space that can be reused for the tensor data is allocated to the tensor data, the allocated memory space is memory space that has been allocated to the M pieces of tensor data before the tensor data, the sorting result indicates a sequence of allocating memory space to the M pieces of tensor data, and the sorting result is related to information about each of the M pieces of tensor data.
