This paper proposes FPGA implementation technique to generate a panoramic view by combining images. Image mosaicing is useful for a variety of tasks in vision and computer graphics. It presents a complete system for stitching a sequence of images with some amount of overlapping between every two successive images. There are three contributions in this paper. First is an image registration method which handles rotation and translation between the two images using FFT phase correlation. Second is an efficient method of stitching of registered images using the registration parameters obtained in previous step using pixel mapping method. Third is image blending where the seam present in the stitched image is removed by weighted average blending method.
