摘要：
In this paper, we propose a system for generating Choroidal NeoVas-cularization (CNV) lesion severity map and evaluating the extent of classic CNV, occult CNV or Pigment Epithelial Detachment (PED) in a Fluorescein Angiog-raphy (FA) sequence. Given an FA sequence, our system first warps each frame to a common coordinate system. For each pixel location in the common coordi-nate system, we use intensity values, intensity changes and area of fluorescence leakage as feature vector for SVM classification. Then, our system generates a severity map associated with the input FA sequence. The severity map will serve to help ophthalmologist perform evaluation of CNV lesion in FA sequence. We have validated our system using patient data from Taipei Veterans General Hospi-tal, Taiwan. The testing data contain 3 classic CNVs, 2 occult CNVs and 2 PEDs. The preliminary results show that our method achieves a promising recognition rate of 85.7%. © 2013 Springer-Verlag Berlin Heidelberg.
