Abstract
Pravovremeno liječenje dijabetičke retinopatije vrlo je važno za sprječavanje razvoja sljepoće kod dijabetičara. Retinopatiju karakteriziraju neovaskularizacije i krvarenja u mrežnici te ih je potrebno pratiti od ranih stadija bolesti. U ovom istraživačkom radu opisan je postupak segmentacije križanja i grananja krvnih žila. Algoritam je razvijen za dva poprečna presjeka krvnih žila – pravokutni i Gaussov. Detektira se središte grananja i križanja žila traženjem i analizom lokalnih ekstrema vlastitih vrijednosti Hessianove matrice u smjeru najznačajnijeg vlastitog vektora.
Abstract (english)
Early treatment of diabetic retinopathy is very important in prevention of blindness development for diabetic patients. Retinopathy is characterized by neovascularization and bleeding in the retina, and must be monitored from the early stages of the disease. This paper describes segmentation of blood vessel crossing and branching. The algorithm is developed for two cross sections of blood vessels - rectangular and Gaussian. The center of vessel branching and crossing is detected by estimating and analysing local extremes of eigenvalues of Hessian matrix in the direction of the most significant eigenvector.
