Abstract
En 中文
• A new explanation based on matrix Lie group theory is presented for the image registration problem. • A matrix formula for subpixel image registration is derived from the correspondence between the cyclic shift Lie group and its Lie algebra. • An efficient algorithm is proposed to solve the subpixel image registration problem in the Lie algebra.
