Filter-cluster attention based recursive network for low-light enhancement Research Article

Zhixiong HUANG, Jinjiang LI, Zhen HUA, Linwei FAN,hzxcyanwind@163.com,lijinjiang@gmail.com-

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 7,   Pages 1028-1044 doi: 10.1631/FITEE.2200344

Abstract: The poor quality of images recorded in low-light environments affects their further applications. To improve the visibility of low-light images, we propose a recurrent network based on (FCA), the main body of which consists of three units: difference concern, gate recurrent, and iterative residual. The network performs multi-stage recursive learning on low-light images, and then extracts deeper feature information. To compute more accurate dependence, we design a novel FCA that focuses on the saliency of feature channels. FCA and self-attention are used to highlight the low-light regions and important channels of the feature. We also design a (DenCP) to extract the color features of the low-light inversion image, to compensate for the loss of the image’s color information. Experimental results on six public datasets show that our method has outstanding performance in subjective and quantitative comparisons.

Building a dense surface map incrementally from semi-dense point cloud andRGBimages

Qian-shan LI,Rong XIONG,Shoudong HUANG,Yi-ming HUANG

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 7,   Pages 594-606 doi: 10.1631/FITEE.14a0260

Abstract: A dense surface map, which offers rich visual and geometric information, is an ideal representation ofpoint cloud and RGB images, we propose a method to generate a consistent and dense surface map fromthis kind of semi-dense point cloud and RGB images.The method contains two main steps: (1) generate a dense surface for every single scan of point cloudNoise within the scan is reduced and a dense surface is generated.

Mouth the mirror of lungs: where does the connection lie?

Jananni Muthu,Sivaramakrishnan Muthanandam,Jaideep Mahendra

Frontiers of Medicine 2016, Volume 10, Issue 4,   Pages 405-409 doi: 10.1007/s11684-016-0476-5

Abstract:

Periodontitis is the chronic destructive disease of the periodontium (Gums) caused by host bacterial interactions. The effect of such host bacterial interactions in oral cavity also evokes a systemic response. Numerous studies have found common mechanisms of destruction for periodontal diseases and other chronic diseases like diabetes mellitus, atherosclerosis, respiratory diseases, and adverse pregnancy outcomes. Oral colonization by respiratory pathogens appears to be a risk factor for development of respiratory diseases and oral interventions aimed at reducing oral bacterial count have resulted in reduced incidence of these reparatory illness. This reflects the importance of oral hygiene among patients with respiratory illness. This review highlights the association between periodontal diseases and respiratory diseases.
