EVALUATION AND PRACTICAL ISSUES OF SUBPIXEL IMAGE REGISTRATION USING PHASE CORRELATION METHODS

In this study we first propose and compare two frequencydomain motion estimation methods using phase correlation principle. Then, we focus on the particular case of subpixel translational movements, we evaluate the accuracy of these two registration methods and we give some practical hints for their implementation. Finally, we compare the performances of these methods for both an ideal theoretical case and for real images.
