چکیده

Automated techniques for eye diseases identification are very important in the ophthalmology field. Conventional techniques for the identification of retinal diseases are based on manual observation of the retinal components (optic disk, macula, vessels, etc.). This paper presents a new supervised method for hemorrhages detection in digital retinal images. This method uses a ANFIS scheme for pixel organization and computes a 5-D vector composed of gray-level and Cross Section Profie Analysis-based features for pixel representation. The method was evaluated on the publicly available DRIVE and STARE databases, widely used for this intention since they contain retinal images where the vascular structure has been precisely marked by experts. Its effectiveness and robustness with different image conditions, together with its simplicity and fast implementation, make this blood vessel segmentation proposal suitable for retinal image computer analyses such as automated screening for early diabetic retinopathy detection.

Morphological Exudate Detection in Retinal Images using PCA-based Optic Disc Removal

Diabetic retinopathy lesion detection such as exudate in fundus image of retina can lead to early diagnosis of the disease. Retinal image includes dark areas such as main blood vessels and retinal tissue and also bright areas such as optic disk, optical fibers and lesions e.g. exudate. In this paper, a multistage algorithm for the detection of exudate in foreground is proposed. The algorithm se...

Automatic Optic Disc Center and Boundary Detection in Color Fundus Images

Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

Early Detection of Diabetic Retinopathy in Fluorescent Angiography Retinal Images Using Image Processing Methods

Introduction: Diabetic retinopathy (DR) is the single largest cause of sight loss and blindness in the working age population of Western countries; it is the most common cause of blindness in adults between 20 and 60 years of age. Early diagnosis of DR is critical for preventing vision loss so early detection of microaneurysms (MAs) as the first signs of DR is important. This paper addresses th...

Automatic Detection of Microaneurysms in Color Fundus Images using a Local Radon Transform Method

Introduction: Diabetic retinopathy (DR) is one of the most serious and most frequent eye diseases in the world and the most common cause of blindness in adults between 20 and 60 years of age. Following 15 years of diabetes, about 2% of the diabetic patients are blind and 10% suffer from vision impairment due to DR complications. This paper addresses the automatic detection of microaneurysms (MA...

Automatic Detection of Microaneurysm using Local Rotating Cross Sectional Profile Analysis

Diabetes is a metabolic disease which damage blood vessel. Damage in retinal blood vessel of the human eye due to effect of diabetes is termed as Diabetic Retinopathy (DR). This abnormality in the blood vessel will cause a leakage of blood from the vessel and forms a red dot. This is named as Microaneurysm. Microaneurysm in the retina causes a swelling of retinal tissue which in turn causes clo...
