Automatic Image Mosaicing: An Approach Based on FFT

In this paper, correlation-based scheme is used which operates in the Fourier domain for finding the transformed coordinates (translational and rotational parameters) and use them for Image Mosaicing. In many clinical studies, it is highly desirable to acquire images as whole sections whilst retaining a microscopic resolution. A usual approach of this is to create a composite image by appropriately overlapping individual images acquired at high magnification under a microscope. In view of this it has been calculated the translational parameters and proposed an algorithm for finding angle of rotation using Fourier Shift approach. Finally it shows merging of two images.
