Abstract This paper presents a generative adversarial network (GAN) with patch match algorithm to realize a high‐quality digital zooming using two camera modules with different focal lengths. In dual camera system, shorter focal length module produces the wide‐view image with the low resolution. On the other hand, the longer focal length module produces the tele‐view image via optical zooming. The long‐focal image contains more details than short‐focal image and can be used to guide short‐focal image to reconstruct high frequency part. Firstly, a feature extraction block (FEB) is advanced to extract feature of long‐focal image and short focal‐image to reconstruct a wide‐view image with different resolutions. Next, a patch match algorithm is integrated into convolution neural networks (CNN) to fuse information of long‐focal with short‐focal image and generate a new fused image. Finally, the fused image and short‐focal image are merged with a feature fusion block (FFB) to predict high‐resolution images. In addition, generative adversarial networks are used for filtering information integrated by previous network and output the zoomed image. Extensive experiments on benchmark datasets show that our algorithm achieves favorable performance against state‐of‐the‐art methods.

MOTIVATION: Recent studies reveal an important role of non-coding circular RNA (circRNA) in the control of cellular processes. Because of differences in the organization of plant and mammal genomes, the sensitivity and accuracy of circRNA prediction programs using algorithms developed for animals and humans perform poorly for plants. RESULTS: A circRNA prediction software for plants (termed PcircRNA_finder) was developed that is more sensitive in detecting circRNAs than other frequently used programs (such as find_circ and CIRCexplorer), Based on analysis of simulated and real rRNA-/RNAase R RNA-Seq data from Arabidopsis thaliana and rice PcircRNA_finder provides a more comprehensive sensitive, precise prediction method for plants circRNAs.
