Abstrak Diabetic retinopathy adalah penyakit mata yang disebabkan kenaikan kadar insulin dalam arah dan penyakit ini merupakan salah satu penyebab utama kebutaan di negara industri. Penyakit ini merupakan penyakit progresif dan membutuhkan deteksi dan penanganan awal. Pola vaskular dari retina manusia membantu opthamologis dalam skrining otomatis dan diagnosa diabetic retinopathy. Pada makalah ini, disajikan sebuah metode untuk segmentasi dan peningkatan pola vaskular. Sistem terotomisasi yang menggunakan wavelets disajikan untuk menaikkan pola vaskular dan kemudian diterapkan pada probing ambang sesepenggal dan pengambangan adaptif untuk kegunaan lokalisasi pembuluh darah dan segmentasi berkaitan. Metode dievaluasi dan diuji menggunakan database retina yang tersedia umum dan lebih jauh metode yang diusulkan dibandingkan dengan teknik yang sudah ada. Kata kunci, diabetic retinopathy, blood vessels, : probing ambang, wavelets Abstract Diabetic retinopathy is an eye disease caused by the increase of insulin in blood and it is one of the main cuases of blindness in idusterlized countries. It is a progressive disease and needs an early detection and treatment. Vascular pattern of human retina helps the ophthalmologists in automated screening and diagnosis of diabetic retinopathy. In this article, we present a method for vascular pattern ehnacement and segmentation. We present an automated system which uses wavelets to enhance the vascular pattern and then it applies a piecewise threshold probing and adaptive thresholding for vessel localization and segmentation respectively. The method is evaluated and tested using publicly available retinal databases and we further compare our method with already proposed techniques.
