ItemRetinal Image Matching Using Hierarchical Vascular FeaturesBhuiyan, A ; Lamoureux, E ; Nath, B ; Ramamohanarao, K ; Wong, TY (HINDAWI LTD, 2011)We propose a method for retinal image matching that can be used in image matching for person identification or patient longitudinal study. Vascular invariant features are extracted from the retinal image, and a feature vector is constructed for each of the vessel segments in the retinal blood vessels. The feature vectors are represented in a tree structure with maintaining the vessel segments actual hierarchical positions. Using these feature vectors, corresponding images are matched. The method identifies the same vessel in the corresponding images for comparing the desired feature(s). Initial results are encouraging and demonstrate that the proposed method is suitable for image matching and patient longitudinal study.
