Single-image super-resolution reconstruction method based on deep residual network
TL;DR: Zhang et al. as mentioned in this paper proposed a single-image super-resolution reconstruction method based on a deep residual network, which mainly comprises a first step of performing block extraction and pixel averaging processing on an image in a sample image database to obtain a corresponding high-resolution and low-resolution training image sets; a second step of constructing a deep convolutional neutral network with a residual structure for iterative training, and then inputting the training set obtained in the first step to the neural network constructed in the second step, according to a data model obtained by training, realizing the

Vehicle radiation imaging detection system
Li Litao,Liqiang Wang,Tan Chunming,Tong Jianmin,Huang Yibin,Liu Jinhui,Wang Zhentao,Guo Xiaojing,Guilai Xing,Zheng Jian +9 more
TL;DR: In this article, the authors proposed a vehicle radiation imaging detection system consisting of a rack, wherein a radiation source, a front collimator and an array detector are arranged on the rack, and a detection channel is formed between the front collimer and the array detector; a ray is collimated into a fan-shaped ray beam with a small penumbra region by virtue of the frontcollimator with a large collimation ratio.
