Frequency Diffeomorphisms for Fast Image Registration

Brown Bag Lecture by Dr. Brown Bag Lecture by Dr. Miaomiao Zhang | 9/19/2017 11:00AM – 11:30AM | 7th Floor Conference Room, Bldg 38A

Abstract:

Large deformation diffeomorphic metric mapping (LDDMM) has been widely used in the field of image registration, atlas-based image segmentation, and anatomical shape analysis. However, the extremely high computational cost and large memory footprint of the current implementations of LDDMM have limited its applicability in important areas that require computational efficiency. In this talk, I will introduce a novel finite dimensional Fourier representation of diffeomorphisms that dramatically speeds up the state-of-the-art diffeomorphic image registration methods while producing equally accurate alignment. Two different applications of image registration are demonstrated: neuroimaging and in-utero imaging.
