Analysis of fundus fluorescein angiogram based on the hessian matrix of directional curvelet sub-bands and distance regularized level set evolution
This paper presents a new procedure for automatic extraction of the blood vessels and optic disk (OD) in fundus fluorescein angiogram (FFA).In order to extract blood vessel centerlines, the algorithm of vessel extraction starts with the analysis of directional images Speed Sensor Clip resulting from sub-bands of fast discrete curvelet transform (FD
