It is important to determine the stable keypoints and select transformation models for image registration and mosaic. In this paper a method is presented for retinal image mosaic. Central to the new method is to detect the PCA-SIFT (Principal Components Analysis-Scale Invariant Feature Transform) feature and estimate the quadratic transformation model which is employed to simulate the anatomy of human eyes. The transformations models are estimated by matching PCA-SIFT landmarks. The hierachical… CONTINUE READING
