Abstract: A vector search method includes: obtaining a to-be-queried vector; searching an index library for a first index corresponding to the to-be-queried vector, where the index library includes a plurality of indexes, each index corresponds to one first cluster, the first cluster includes a plurality of second clusters, each index records a first cluster center vector and a plurality of second cluster center vectors, feature vectors corresponding to the first cluster are clustered using the first cluster center vector, and feature vectors corresponding to each second cluster are clustered using each second cluster center vector; searching the first index for a second cluster center vector corresponding to the to-be-queried vector; finding a second cluster corresponding to the second cluster center vector based on the second cluster center vector; and searching a plurality of feature vectors included in the second cluster for a target feature vector related to the to-be-queried vector.

Abstract: A viewpoint image processing method and a related device are provided, and relate to the artificial intelligence/computer vision field. The method includes: obtaining a preset quantity of first viewpoint images; obtaining a geometric feature matrix between the preset quantity of first viewpoint images; generating an adaptive convolution kernel corresponding to each pixel of the preset quantity of first viewpoint images based on the geometric feature matrix and location information of a to-be-synthesized second viewpoint image, where the location information represents a viewpoint location of the second viewpoint image; generating the preset quantity of to-be-processed virtual composite pixel matrices based on the adaptive convolution kernels and the pixels of the preset quantity of existing viewpoint images; and synthesizing the second viewpoint image by using the preset quantity of to-be-processed virtual composite pixel matrices. The method can improve efficiency and quality of synthesizing the second viewpoint image.

Abstract: The embodiments of the present invention provide a method and a trusted gateway for a WiFi terminal to access a PS service domain. The method comprises: receiving an accounting request message sent by an authentication, authorization and accounting AAA server or a dynamic host configuration protocol DHCP request message sent by the WiFi terminal; establishing, by a trusted gateway, a first packet data protocol PDP context connection or a first packet data network PDN connection with the PS service domain according to attribute information of the WiFi terminal after receiving the accounting request message or the DHCP request message, so that the WiFi terminal accesses the PS service domain via the wireless local area network, the trusted gateway, and the established first PDP context connection or the first PDN connection.
