THE PRACTICE OF AUTOMATIC SATELLITE IMAGE REGISTRATION
Jianchao Yao, Chia Tien Chern · 2001
In this paper, a new algorithm for satellite image registration was developed. The main characteristic of the algorithm is to align two images automatically, without requiring either control points or sensor's parameters. Two kinds of models, characterising the image variability between images, were utilised. One is projective model, accounting for geometrical variation . The other is the polynomial illumination change model, accounting for the variation in illumination at different time. These two model parameters can be simultaneously estimated via the intensity matching, using the Levenberg-Marquardt minimisation framework incorporated with multi-resolution and multiple model strategy. The algorithm has been verified by an intensive experiment on a great number of real images, taken by satellite, digital and frame camera. The Experimental result demonstrates the robustness, efficiency and accuracy of the algorithm.
