A HYBRID FILTERING APPROACH TO RETINAL VESSEL SEGMENTATION
"... We propose a novel vessel enhancement filter for retinal images. The filter can be used as a preprocessing step in applications such as vessel segmentation/visualization, and pathology detection. The proposed filter combines the eigenvalues of the Hessian matrix, the response of matched filters, and ..."

A new approach to automated retinal vessel segmentation using multiscale analysis
- In ICPR
, 2006
"... Computer based analysis for automated segmentation of blood vessels in retinal images will help eye care specialists screen larger populations for vessel abnormalities. However, automated retinal segmentation is complicated by the fact that the width of retinal vessels can vary from very large to ve ..."

RETINAL VESSEL DETECTION USING SELF-MATCHED FILTERING
"... ABSTRACT Automated analysis of retinal images usually requires estimating the positions of blood vessels, which contain important features for image alignment and abnormality detection. Matched filtering can produce the best results but is difficult to implement because the vessel orientations and ..."

was implemented in two conditions known for being associated with retinal vessel changes: hypertensive retinopathy and Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL). The results showed that our approach is effective in detecting and quantifying the retinal
A Novel Hybrid Approach Using Kmeans Clustering and Threshold filter for Brain Tumor Detection
"... Abstract-Medical imaging makes use of the technology to disclose the internal structure of the human body. By means of medical imaging modalities patient's life can be better through a accurate and quick treatment without any side effects. The foremost purpose of this paper is to develop an au ..."

an automated framework that can accurately classify a tumor from abnormal tissues. In this paper, we put forward a hybrid framework that uses the K-means clustering followed by Threshold filter to track down the tumor objects in magnetic resonance (MR) brain images. The main concept in this hybrid framework
1 Segmentation and Enhancement of Retinal Images using Morphological Operations R.Anjali
"... Different types of techniques are used to detect and segment the retinal diseases. Each technique gives a level of accuracy. Morphological methods have been extensively used in handling medical images. The goal of morphological operations is to remove imperfections by considering the structure of th ..."

This paper proposes an automated method to detect, (1) lesions in Diabetic retinopathy (2) pigment epithelial detachment in Wet age- related- macular-degeneration (3) soft drusen in Dry age- related- macular-degeneration and (4) haemorrhages in Central retinal vein and artery occlusion. A three
An Efficient ELM Approach for Blood Vessel Segmentation in Retinal Images �
"... Abstract--- Diabetic Retinopathy (DR) is one of the most important ophthalmic pathological reasons of blindness among people of working age. Previous techniques for blood vessel detection in retinal images can be categorized into rulebased and supervised methods. This research presents a new supervi ..."

supervised technique for blood vessel detection in digital retinal images. This novel approach uses an Extreme Learning Machine (ELM) approach for pixel classification and calculates a 7-D vector comprises of gray-level and moment invariants-based features for pixel representation. The approach is based
Detection of Diabetic Retinopathy using Splat Feature Classification in Fundus Image
