Abstract: This study proposes a medical image registration method using two algorithms [Fast Walsh Had amard transform (FWHT)and Modified Adaptive Polar transform (MAPT)], which register images of same or different modalities using CT or / and MRI brain images. FWHT gave better results than MAPT. In medical image registration of brain images, FWHT is more reliable for translation and rotation invariant, whereas MAPT is more reliable for scaling and rotation invariant. Hence for registration of brain images using translation and rotation, FWHT can be used, and for registration of brain images using rotation and scaling, MAPT can be used.
