For example, network communication requires Android’s network request technology and data analysis technology. The display of pictures requires the use of Android controls and cache technology. The traceability of products requires camera scanning technology. And RSA decryption technology and so on. Through the above thread pool technology and the use of caching mechanism, the user experience of UI will be improved and unnecessary network resources consumption will be avoided.展开更多

In this paper, we propose a novel method called distributed compressed sensing for image using block measurements data fusion. Firstly, original image is divided into small blocks and each block is sampled independently using the same measurement operator, to obtain the smaller encoded sparser coefficients and stored measurements matrix and its vectors.? Secondly, original image is reconstructed using the block measurements fusion and recovery transform. Finally, several numerical experiments demonstrate that our method has a much lower data storage and calculation cost as well as high quality of reconstruction when compared with other existing schemes. We believe it is of great practical potentials in the network communication as well as pattern recognition domain.展开更多
