Perspective-SIFT: An efficient tool for low-altitude remote sensing image registration
We use homographic transform to simulate multi-view perspective distortion. A two-resolution scheme has been used to speed up the sampling process. We prove that the complexity of PSIFT is about twice that of ASIFT. PSIFT outperforms state-of-the-art methods when images suffer severe perspective distortion.
