Glaucoma is a silent disease that leads to vision loss or irreversible blindness. Current deep learning methods can help glaucoma screening by extending it larger populations using retinal images. Low-cost lenses attached mobile devices increase the frequency of and alert patients earlier for more thorough evaluation. This work explored compared performance classification segmentation with images acquired both retinography devices. The goal was verify results these see if similar could be...
Public databases for glaucoma studies contain color images of the retina, emphasizing optic papilla. These are intended research and standardized automated methodologies such as those using deep learning techniques. techniques used to solve complex problems in medical imaging, particularly screening glaucomatous disease. The development has demonstrated potential implementing protocols large-scale population, eliminating possible diagnostic doubts among specialists, benefiting early...
In this paper we present an anonymous protocol for a mobile payment system based on Kiosk Centric Case Mobile Scenario where the customer cannot communicate with issuer due to absence of Internet access her device and costs implementing other mechanism communication between both them are high. Our protects real identity clients during purchase employs digital signature scheme message recovery using self-certified public keys that reduces space cost in comparison certificate-based schemes....
Great advances in stitching high-quality retinal images have been made recent years. On the other hand, very few studies carried out on low-resolution imaging. This work investigates challenges of obtained by D-EYE smartphone-based fundus camera. The proposed method uses homography estimation to register and stitch low-quality into a cohesive mosaic. First, Siamese neural network extracts features from pair images, after which correlation their feature maps is computed. map fed through four...
The security of RELOAD, a protocol developed by the IETF for session initiation (SIP) communications over peer-to-peer (P2P) networks, is based on each user's possession public key certificate that links her identity (username) with device (nodeID) and key. In this study, authors will analyse flaw in its design related to joint certification devices users, present new proposal separation. authors' RELOAD are evaluated under several scenarios show how their approach separation users provides...
Glaucoma is one of the leading causes irreversible blindness in world. Early diagnosis and treatment increase chances preserving vision. However, despite advances techniques for functional structural assessment retina, specialists still encounter many challenges, part due to different presentations standard optic nerve head (ONH) population, lack explicit references that define limits glaucomatous neuropathy (GON), specialist experience, quality patients’ responses some ancillary exams....
Ideally, to carry out screening for eye diseases, it is expected use specialized medical equipment capture retinal fundus images. However, since this kind of generally expensive and has low portability, with the development technology emergence smartphones, new portable cheaper options have emerged, one them being D-Eye device. When compared equipment, other similar devices associated a smartphone present lower quality less field-of-view in video captured, yet sufficient perform...
