    1. A Simple Algorithm for Hard Exudate Detection in Diabetic Retinopathy Using Spectral-Domain Optical Coherence Tomography

      A Simple Algorithm for Hard Exudate Detection in Diabetic Retinopathy Using Spectral-Domain Optical Coherence Tomography

      Hard exudates are usually seen in the course of diabetic retinopathy. This illness is one of the most common reasons for blind registration in the world. Due to the data presented by World Health Organization (WHO) the number of people who lose sight because of undetected diabetes will be doubled by 2050. The purpose of this paper is to introduce an enhanced algorithm for hard exudates detection in Optical Coherence Tomography images. In these samples, dangerous pathological changes can be observed in the form of yellow-red spots. During the experiments more than 150 images were used to calculate the accuracy ...

    2. Retina Tomography and Optical Coherence Tomography in Eye Diagnostic System

      Retina Tomography and Optical Coherence Tomography in Eye Diagnostic System

      Eye diagnostic, two-step method based on retina color image and Optical Coherence Tomography is presented in this paper. A new robust algorithm, by which various eye diseases can be diagnosed, was implemented as an essential part of the work. The approach comprises two steps. The first one deals with the analysis of retina color image. In this stage, an algorithm was implemented to especially search hard exudates. If the algorithm returns positive, it means at least one hard exudate was found. Moreover, it may return hesitant results in the case of changes that look like hard exudates. During the second ...

    3. A Novel Approach of Retinal Disorder Diagnosing Using Optical Coherence Tomography Scanners

      A Novel Approach of Retinal Disorder Diagnosing Using Optical Coherence Tomography Scanners

      OCT is a promising technology that allows getting a lot of data in each sample. Authors hope that it is possible to create a system that would automatically diagnose various retinal diseases basing on OCT images with the accuracy of 95% which may revolutionize and shorten diagnostic pathway. At the beginning authors focus on automatic distinguishing the healthy images from pathological retinas. In this paper a novel approach has been presented. The algorithm has been described and results have been revealed and discussed. OCT is a way for detecting many various diseases. However, the amount of information to be processed ...
