Fast 3-D medical image registration algorithm using Hotelling transform
Wufan Chen · Computer Engineering and Applications Journal · 2007
This paper presents a new 3-D image registration method based on the Hotelling transform.Compared with intensity based registration methods using the whole volume intensity information,the approach utilizes Hotelling transform to align images.The authors evaluate the effectiveness of this approach by applying it to the simulated and real brain image data(MR,CT,PET,and SPECT).The experimental results indicate that the algorithm is effective,especially for 3-D medical images.
