Figure 10From: An efficient approach for robust multimodal retinal image registration based on UR-SIFT features and PIIFD descriptors Results for multimodal image pairs: RF-FA, AF-color, and color-SLO. The first row exhibits an RF and venous phase of its FA sequence in a retina with dilated blood vessels. The scaling factors of the image pairs are 1.5, 1.5, and 2.5, respectively. The Harris-PIIFD failed to register these images.Back to article page
