The DIARETDB1 diabetic retinopathy database and evaluation protocol Authors: Kauppi Tomi, Kalesnykiene Valentina, Kmrinen Joni-Kristian, Lensu Lasse, Sorri Iiris, Raninen Asta, Voutilainen Raija, Pietil Juhani, Klviinen Heikki, Uusitalo Hannu Automatic diagnosis of diabetic retinopathy from digital fundus images has been an active research topic in the medical image processing community. The research interest is justified by the excellent potential for new products in the medical industry and significant reductions in health care costs. However, the maturity of proposed algorithms cannot be judged due to the lack of commonly accepted and representative image database with a verified ground truth and strict evaluation protocol. In this study, an evaluation methodology is proposed and an image database with ground truth is described. The database is publicly available for benchmarking diagnosis algorithms. With the proposed database and protocol, it is possible to compare different algorithms, and correspondingly, analyse their maturity for technology transfer from the research laboratories to the medical practice.

Early detection of retinopathy can rescue patients from vision loss. Therefore, in this paper we propose an automatic severity level assessment of the diabetic retinopathy using innovative image processing techniques combined with a multi-layered artificial neural network model for classification of retina images. The color retina images are collected from the standard DIARECTDB1 and MESSIDOR datasets. The collected data includes the images of normal eyes, as well as the images of mild, moderate and severe cases of Non-Proliferative Diabetic Retinopathy (NPDR).

Diabetic Retinopathy Screening System: A Validation Analysis With Multiple Fundus Image Databases
Research Article - Biomedical Research (2017) Volume 28, Issue 4 Diabetic retinopathy screening system: A validation analysis with multiple fundus image databases Annie Grace Vimala GS 1 * and Kaja Mohideen S 2 1 Department of Electronics and Communication Engineering, St. Josephs Institute of Technology, Chennai, India 2 Department of Electronics and Communication Engineering, BS Abdur Rahman University, Chennai, Tamil Nadu,India Department of Electronics and Communication Engineering St. Josephs Institute of Technology, India Visit for more related articles at Biomedical Research Diabetic Retinopathy (DR) is one of the most common health problems of long-standing diabetes. It is a progressive disease and finally results in blindness. Early detection of diabetic retinopathy can prevent the damage to the retina and vision loss or at least slow its progression. The aim of the present study was to develop a Computer Aided Diagnostic System (CAD) in order to diagnose diabetic retinopathy by extracting blood vessels, optic disc and exudates from retinal digital fundus images and to validate the system with multiple image databases. The digital color fundus images obtained from 60 Indian women, 40 images from Digital Retinal Images for Vessel Extraction (DRIVE) database, 40 images from Structured Analysis of Retina (STARE) database and 89 images from DIARETDB1 database were used for the present study. For each image the hand drawn ground truth result was collected. Then the quantitative analysis of the proposed algorithm with Support Vector Machine (SVM) classifier has been carried out and the results are compared against the ground truth. The extracted features such as mean intensity, mean area of the segmented region, number of segmented regions and solidity were displaye Continue reading >>

A TWO-PHASE PRE-FILTERING APPROACH TO THE AUTOMATIC SCREENING OF DIGITAL FUNDUS IMAGES Blint Antal, Andrs Hajdu, Adrienne Csutak, Tnde Pet In this paper, we present an approach to decrease the computational burden of an automatic screening system designed for diabetic retinopathy. The proposed method consists of two steps. First, a pre-screening algorithm is considered to classify the input digital fundus images based on their abnormality. If an image is found to be abnormal, it will not be analyzed further with robust lesion detector algorithms. As an improvement, we introduce a novel feature extraction approach based on clinical observations. The second step of the proposed method detects regions which contain possible lesions for images that have been passed pre-screening. These regions will serve as inputs to lesion detectors later on, which can achieve better computational performance by operating on specific regions only instead of the entire image. Experimental results show that both two steps of the proposed approach are valid to efficiently exclude a large amount of data from further processing to improve the performance of an automatic screening system.

A Framework For Constructing Benchmark Databases And Protocols For Retinopathy In Medical Image Analysis
A Framework for Constructing Benchmark Databases and Protocols for Retinopathy in Medical Image Analysis Part of the Lecture Notes in Computer Science book series (LNCS, volume 7751) We address performance evaluation practices for developing medical image analysis methods, and contribute to the practice to establish and to share databases of medical images with verified ground truth and solid evaluation protocols. This helps to develop better algorithms, to perform profound method comparisons, including the state-of-the-art methods, and consequently, supports technology transfer from research laboratories to clinical practice. For this purpose, we propose a framework consisting of reusable methods and tools for the laborious task of constructing a benchmark database. We provide a medical image annotation software tool which helps to collect and store ground truth for retinopathy lesions from experts, including the fusion of spatial annotations from several experts. The tool and all necessary functionality for method evaluation are provided as a public software package. For demonstration purposes, we utilise the framework and tools to establish the DiaRetDB1 V2.1 database for benchmarking diabetic retinopathy detection algorithms. The database contains a set of retinal images, ground truth from several experts, and a strawman algorithm for the detection of retinopathy lesions.

Detection Of Hard Exudates In Diabetic Retinopathy Retinal Images By Utilizing Visual Dictionary And Classifier Approaches | Akyol | Mugla Journal Of Science And Technology
DETECTION OF HARD EXUDATES IN DIABETIC RETINOPATHY RETINAL IMAGES BY UTILIZING VISUAL DICTIONARY AND CLASSIFIER APPROACHES Diabetic retinopathy is a disease that causes blindness resulting from damages that emerge in the retina depending on the diabetes mellitus. There are two stages of the disease including the non-proliferative and proliferative. Eyesight loss is blocked by means of early detection and diagnosis of non-proliferative DR findings. In this study, we designed a decision support system for automatic detection of hard exudates which are early stage DR lesions. This system consists of region-of-interest, feature extraction, visual dictionary and classifying stages. We tested the performance of the system, which we carried out based on system learning and analysis of new retinal images, on the public DIARETDB1 retinal image dataset. Experimental results showed us that machine learning technique suggested by us is successful.

Segmentation Of Exudates And Optic Disc In Retinal Images
Segmentation of Exudates and Optic Disc in Retinal Images 2008 Sixth Indian Conference on Computer Vision, Graphics & Image Processing,535-542,2008 Giri Babu Kande - S.R.K. Institute of Technology Vijayawada Andhra Pradesh India P. Venkata Subbaiah - Amrita Sai Institute of Science & Technology Paritala Andhra Pradesh India T. Satya Savithri - Jawaharlal Nehru Technological University, Hyderabad This paper proposes two efficient approaches for automatic detection and extraction of Exudates and Optic disk in ocular fundus images. The localization of optic disk is composed of three steps. First the centre of optic disk is estimated by finding a point that has maximum local variance. The color morphology in Lab space is used to have homogeneous optic disk region. The boundary of the optic disk is located using geometric active contour with variational formulation. The Exudates identification involves Preprocessing, Optic disk elimination, and Segmentation of Exudates. In Exudates detection the enhanced segments are extracted based on Spatially Weighted Fuzzy c-Means clustering algorithm. The Spatially Weighted Fuzzy c-Means clustering algorithm is formulated by incorporating the spatial neighborhood information into the standard FCM clustering algorithm. The Experimental results of both approaches are validated with ground truth images. The proposed algorithm for optic disk detection produces 92.53% accuracy. The sensitivity and the specificity of the proposed algorithm for exudates detection are 86% and 98% respectively. 2018 Digital Science & Research Solutions, Inc.
