Fourier Based Image Registration for Sub-Pixel Using Pyramid Edge Detection and Line Fitting

Image registration has been widely used in many works of image processing. But it is difficult to find the accuracy information such as translation, rotation, and scaling between images. This paper proposes an algorithm that Fourier based image registration using the pyramid edge detection and line fitting. It is possible to find the registration information of sub-pixel. So, we can find more accurate registration information. The proposed algorithm can be used for image registrations which high efficiency is required such as GIS, or MRI, CT, image mosaicing, weather forecasting, etc.
