Multi-focus Image Fusion using Fully Convolutional Two-stream Network for Visual Sensors
( Kaiping Xu ),( Zheng Qin ),( Guolong Wang ),( Huidi Zhang ),( Kai Huang ),( Shuxiong Ye ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.5
We propose a deep learning method for multi-focus image fusion. Unlike most existing pixel-level fusion methods, either in spatial domain or in transform domain, our method directly learns an end-to-end fully convolutional two-stream network. The framework maps a pair of different focus images to a clean version, with a chain of convolutional layers, fusion layer and deconvolutional layers. Our deep fusion model has advantages of efficiency and robustness, yet demonstrates state-of-art fusion quality. We explore different parameter settings to achieve trade-offs between performance and speed. Moreover, the experiment results on our training dataset show that our network can achieve good performance with subjective visual perception and objective assessment metrics.

Bactrocera (Zeugodacus) tau (Walker) (Diptera: Tephritidae), a quarantine pest of international concern, has become widespread and economically important in South and Southeast Asia. It has been introduced into north Jiangxi from Fujian, China and become a threat to local fruits and vegetables. Field trapping with cuelure (CUE) as lure is needed, not only for monitoring population dynamics of B. tau but also for direct control of population. In this study, we collected weekly tephritids from 4 CUE-baited McPhail traps every year from 2008 to 2015, analysing seasonal and inter-year B. tau population fluctuations. The total number of captured tephritids reached 7811, including B. tau (5321), B. scutellata (Hendel) (2375) and B. cucurbitae (Coquillett) (1 1 5). Among them, B. tau was the dominant species. It had 3–4 generations a year in north Jiangxi with high generation overlapping. The average number of trapped B. tau males did not differ significantly in different years, while the average monthly number showed large variation from June to December. No B. tau males were trapped before June in any year. Adult males were present from mid-June to late December, with distinct peaks between late August and mid-October. This fruit fly can withstand below 13℃ as a monthly minimal temperature under field conditions, and adult capture rates were significantly related to monthly minimal temperature and monthly total precipitation. These results can be used to predict the occurrence time and population size of B. tau in different seasons, enabling growers and extension personnel to take efficient management measures before they damage the host crops.

Studies have confirmed that Angelica sinensis, which is a famous medicinal food in China, can effectively alleviate the symptoms of ulcerative colitis (UC) in rats. However, as the major water-soluble ingredient, the specific effects of A. sinensis polysaccharide (ASP) on UC and potential mechanisms were uncertain. In this study, we aimed to elucidate the protective effects of ASP on dextran sulfate sodium (DSS)-induced UC and to further explore the mechanisms. ASP could significantly ameliorate the symptoms of weight loss, disease activity index score, and colon shortening caused by DSS. ASP treatment also significantly suppressed the myeloperoxidase activity in colon tissues. Furthermore, after ASP administration, the expression of the proinflammatory cytokines (interleukin [IL]-6, IL-1β, and tumor necrosis factor alpha) induced by DSS was remarkably suppressed, and there was a definite improvement in the expressions of tight junction proteins, such as zona occludens 1, occludin, and claudin-1. In addition, the results of apoptosis experiments showed that the apoptotic events were noticeably reduced after ASP treatment. Taken together, these results suggested that ASP may be a potential natural agent against UC.
