Abstract: This application relates to the field of computer technologies, augmented reality (AR) technologies, and more particularly to method and apparatus for detecting a pose of an AR device. The method includes obtaining, by emitting detection light to the AR device, two acquired images based on photographing positions, each of the acquired images comprising image feature points based on device feature points on the AR device; determining respective distances of at least two target image feature point pairs based on the at least two acquired images, the two target image feature point pairs comprising a common target image feature point; determining target device feature points respectively corresponding to the target image feature points on the AR device; and determining pose information of the AR device based on respective position information of the target device feature points and the target image feature points.

Abstract: The present disclosure provides methods, devices and systems that enable determination of spatial information of biological molecules by reacting the biological molecules with a zipcode array. In some examples, the zipcode array may code for the spatial positions of biological molecules attached to distinct positions on the zipcode array. In some examples, the spatial positions are 2-dimensional. In some cases, the spatial positions are 3-dimensional. In some examples, the present disclosure provides methods to detect spatial gene expression. In some examples, the present disclosure provides methods to detect spatial distribution of proteins.

The method includes: obtaining desktop elements; placing the desktop elements on the desktop area; receiving requests for modifying the desktop elements; and modifying the desktop elements according to the requests for modification. The method and system for dynamic modification of desktop layout and computer storage medium thereof could modify desktop elements according to requests for modifying desktop elements; the desktop elements could be elastically modified to meet different demands.

Abstract: An image management method is disclosed. The method includes: receiving images; caching the received images to a memory space; determining if free memory size is less than the threshold, if yes, releasing the memory space. According to the method, mobile terminal and computer storage medium, the free memory size is determined if less than the threshold in the process of obtaining images, if yes, the memory space is released. In this way, the memory could be saved so as to provide enough space for image processing, which reduces the incidence of errors and improves the efficiency during manipulating the image.
