Diabetic retinopathy (), also known as diabetic eye disease, is when damage occurs to the retina due to diabetes. It can eventually lead to blindness.
It is an ocular manifestation of diabetes, a systemic disease, which affects up to 80 percent of all patients who have had diabetes for 20 years or more. Despite these intimidating statistics, research indicates that at least 90% of these new cases could be reduced if there were proper and vigilant treatment and monitoring of the eyes. The longer a person has diabetes, the higher ....etc

feature extraction using curvelet transform

Introduction

Designing a completely automatic and efficient face recognition system is a grand challenge for biometrics, computer vision and pattern recognition researchers. Generally, such a recognition system is able to perform three subtasks: face detection, feature extraction and classification. We ll put our focus on feature extraction, the crucial step prior to classification. The key issue here is to construct a representative feature set that can enhance system-performance both in terms of ....etc

Abstract

Background

Despite significant progress in imaging technologies, the efficient detection of edges and elongated features in images of intracellular and multicellular structures acquired using light or electron microscopy is a challenging and time consuming task in many laboratories.

Results

We present a novel method, based on the discrete curvelet transform, to extract a directional field from the image that indicates the location and direction of the edges. This directional field is then processed using the non-maximal suppression ....etc

Accurate measurement and classification of blood vessels could provide useful information to clinical diagnosis. Abnormalities in diameter of retinal blood vessels and presence of unusual
artefacts on retinal image are usually the first clinical finding in many retinal diseases, like diabetic retinopathy etc. Manual segmentation of retinal blood vessels is a long and tedious task
which also requires skill. That is why automatic delineation and classification of retinal vessels, and general evaluation of retinal images is the first step in the d ....etc

Abstract

Recently, Cand es and Donoho (1999) introduced the curvelet transform, a new multiscale representation suited for objects which are smooth away from discontinuities across curves. Their proposal was intended for functions f defined on the continuum plane R2. In this paper, we consider the problem of realizing this transform for digital data.We describe a strategy for computing a digital curvelet transform, we describe a software environment, Curvelet256, implementing this strategy in the case of 256 256 images, and we describe some e ....etc
