Abstract: In a method for selecting pictures from a sequence of pictures of an object in motion, a computerized user device determines, for each picture in the sequence of pictures, a value of a motion feature of the object. Based on analyzing the values of the motion feature of the pictures in the sequence, the device identifies a first subset of pictures from the pictures in the sequence. The device then selects, based on a second selection criterion, a second subset of pictures from the first subset of pictures. The pictures in the second subset are displayed to a user for further selection.

Abstract: A memory access processing method and apparatus, and a system. The method includes receiving a memory access request sent by a processor, combining multiple memory access requests received within a preset time period to form a new memory access request, where the new memory access request includes a code bit vector corresponding to memory addresses. A first code bit identifier is configured for the code bits that are in the code bit vector and corresponding to the memory addresses accessed by the multiple memory access requests. The method further includes sending the new memory access request to a memory controller, so that the memory controller executes a memory access operation on a memory address corresponding to the first code bit identifier. The method effectively improves memory bandwidth utilization.

Abstract: An image processing apparatus and a method are provided. The apparatus comprises a plurality of processing modules configured to operate in series to refine a raw image captured by a camera, the modules comprising a first module and a second module, each of which independently implements a respective trained artificial intelligence model, wherein: the first module implements an image transformation operation that performs an operation from the set comprising: (i) an essentially pixel-level operation that increases sharpness of an image input to the module, (ii) an essentially pixel-level operation that decreases sharpness of an image input to the module, (iii) an essentially pixel-block-level operation on an image input to the module; and the second module as a whole implements a different operation from the said set.

Abstract: Multiple lock assemblies are distributed on a chip, each lock assembly manage a lock application message for applying for a lock and a lock release message for releasing a lock that are sent by one small core. Specifically, embodiments include receiving a lock message sent by a small core, where the lock message carries a memory address corresponding to a lock requested by a first thread in the small core; calculating, using the memory address of the requested lock, a code number of a lock assembly to which the requested lock belongs; and sending the lock message to the lock assembly corresponding to the code number, to request the lock assembly to process the lock message.
