Research ArticleOpen accessEvery word in the titleTransforming Retinal Diagnostics: Advanced Detection of Diabetic Retinopathy Using Vision Transformers and Capsule NetworksVishal Sharma, Rishu, Vinay Kukreja et al.Diabetic Retinopathy (DR), nowadays is one of the leading causes of blindness worldwide, it is a severe complication of diabetes mellitus that affects the retina blood vessels. Accurate diagnosis depends on early detection of DR. The study aims to develop a hybrid model that is the combination of a Vision Transformer and Capsule Network (ViT-CapsNet) to classify the DR at … …Journal of Computer Science, Vol. 21, Issue 2 · 14 Jan 2025 · 6,765 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBLOOD VESSEL DIAMETER MEASUREMENT ON RETINAL IMAGENidhal K. El Abbadi, Enas Al SaadiAccurate measurement of vessel diameters on retinal images plays an important part in diagnosing cardiovascular diseases and early signs of certain systemic diseases, such as diabetes and hypertension. In this study we develop new method based on computer aided to determine the width of retinal blood vessels by analysing the color fundus image. Retinal vessel diameter was measured based on … …Journal of Computer Science, Vol. 10, Issue 5 · 18 Jan 2014 · 7,533 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleResearch on Cotton Top Bud Target Detection Algorithm Based on Improved RetinaNetJikui Zhu, Shijie Lin, Fengkui Zhang et al.To solve the problems of low accuracy and high miss rate in the recognition of cotton apical buds during mechanical topping, an enhanced method based on the RetinaNet network is proposed for the accurate identification of cotton apical buds under natural light. The traditional RetinaNet algorithm is validated to improve the recall rate and average accuracy of cotton apical bud … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 17 Apr 2024 · 5,140 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAutomatic Detection of Exudates in Retinal Images using Region-Based, Neighborhood and Block OperationKittipol Wisaeng, Worawat Sa-NgiamviboolExudates detection is one of the research areas attracting great attention of physicians and scientists. A region-based, neighborhood, block operation and optimal global thresholding are proposed as new methods to exudates detection. The exudates are coarse and fine segmentation following preprocessing steps, i.e., color mapping, image contrast enhancement, fuzzy filtering and optic disc localization. To classify the retinal images into … …Journal of Computer Science, Vol. 14, Issue 4 · 21 Feb 2018 · 7,987 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMesenchymal Stem Cell Transplantation for Retinal Degenerations and Dystrophies: Present and FutureEmma Ghazaryan, Shurong Wang, Yan Zhang et al.Retinal degenerations are the main causes of irreversible blindness in developed countries. Up to date the main pathological mechanisms of these diseases are not fully understood and consequently there is no complete treatment option for those diseases. In this aspect stem cells have drawn attention of many researchers and health care professionals. Considering ethical issues, safety and facile isolation Mesenchymal … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 28 Nov 2014 · 6,768 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAUTOMATIC RETINAL VESSEL TORTUOSITY MEASUREMENTNidhal Khdhair El Abbadi, Enas Hamood Al SaadiRetinal vascular vessels have the role to indicate the retinal diseases and for systematic diseases when there are any abnormalities in retinal vascular pattern. A characteristic of the vascular pattern that is appreciated by clinicians is vascular tortuosity, i.e., how curved or kinked a blood vessel, either vein or artery, appears along its course. In this study we suggest a … …Journal of Computer Science, Vol. 9, Issue 11 · 21 Sep 2013 · 7,213 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Hybrid Retinal Image Registration Using Mutual InformationPradeepa Palraj, Ila VennilaImage registration has tremendous applications in medical industry both in diagnosis and therapy. But registering the retinal images is very difficult task because of the structural and illumination criteria. Normal registration algorithms are proved to be less effective and more complicated for such applications. This study aims at combining two methods of retinal image registration: Vessel based and non-vessel based … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 18 Sep 2013 · 6,694 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRetinal Image Analysis for Abnormality Detection-An OverviewR. Karthikeyan, P. AlliProblem statement: Classification plays a major role in retinal image analysis for detecting the various abnormalities in retinal images. Classification refers to one of the mining concepts using supervised or unsupervised learning techniques. Approach: Diabetic retinopathy is one of the common complications of diabetes. Unfortunately, in many cases, the patient is not aware any symptoms until it is too late … …Journal of Computer Science, Vol. 8, Issue 3 · 24 Jan 2012 · 7,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAttenuated Superoxide Dismutase Induction in Retinal Cells in Response to Intermittent High Versus Continuous High GlucoseMichael A. Ihnat, Ronald C. Kaltreider, Jessica E. Thorpe et al.High glucose, particularly in oscillating conditions, produces an increase in oxidative stress and has been shown to result in an increase in diabetic complications, retinopathy in particular. The hypothesis of this work was that chronic exposure to intermittent high glucose results in an attenuated induction of an antioxidant response as compared to continuous high glucose exposure in isolated retinal cells … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 7,458 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCloud Based Low Cost Retinal Detachment Screening Method Using Data Mining TechniquesMahmoud A. Fakhreldin, Ahmed F. SeddikThe Electro-Oculogram (EOG) signal can be used for detecting the normality of the eye retina. A number of advantages including the flexibility of the recoding process for EOG signals have encouraged insight into EOG based research. This study proposes a new cloud based retinal detachment screening technique based on data mining techniques to diagnose the type of eye retina. The … …Journal of Computer Science, Vol. 13, Issue 11 · 5 Oct 2017 · 6,833 accessesView PDFCite
