A parametric elastic registration method for airborne multispectral line scan imager

The multispectral line scan imager is widely used in aerial remote sensing application. However, there is different none-linear warping and local transformation between bands, due to the vibration of the platform and out of synchronizing of bands imaging exposure time. This paper describes a parametric elastic registration method to model the multispectral image registration problem. This approach deeply explores the prior knowledge of the imaging mechanism and the attitude parameters constraint of the stable platform, which is helpful for improve the quality and robustness of the multispectral image registration. We formulate the elastic registration problem of multispectral image as a nonlinear minimization optimization problem. Experimental results of the real flight images shown that the proposed method could well deal with the none-linear warping of airborne multispectral images.
