Abstract

The quality of polarimetric images deduced from three different angle radiometric images depends greatly on the accuracy of the images registration. The researches indicate that image misregistration with 1110th order of magnitude of a pixel can introduce artifacts in polarization images. Typically translation rotation and scaling are the main image deformations to be corrected. It is desirable to have a registration algorithm that corrects translations rotations and scaling to 0th of a pixel just based on analytical automated calculation without user intervention. This paper presents an automated image registration algorithm by using wavelet transform technique. The algorithm relies on the local wavelet transform modulus maxima of the images. Examples of images registered with this algorithm are presented. The results testify this method is effective to correct the image misregistration of three different angle radiometric images.
