Fast image alignment with Fourier moment matching on GPU

In this paper, we develop a fast and accurate image alignment system which can be applied to image sequences in real time. The proposed image alignment system consists of two main components: the development of Fourier moment matching system and the implementation of the system in GPU. The Fourier moment matching is to efficiently find the location, orientation and size of the template from an input image. The GPU implementation speeds up the computation of the Fourier moment matching for the image alignment system to achieve real-time computation.
