“Mosaic” originates from an Old Italian word “mosaico” which means a picture or pattern produced by arranging together small pieces of stone, tile, glass etc. The input images which are to be stitched can be two or more than that and is better understood from the geometric relationship between them [1, 2]. It has got many real time applications. Panorama is very common example which is used in our daily life. Image mosaicing algorithm is broadly divided into two categories: spatial domain based and frequency domain based. Spatial domain based is further classified into area based and feature based image mosaicing. So SURF (Speeded-Up Robust Features) algorithm implemented completely works in the spatial domain to generate the mosaiced image. In the proposed methodology the corresponding information or details in each individual image scenes in spatial and temporal domain can be combined to generate scene using images of smaller field of view. In frequency domain FFT (Fast Fourier Transform) approach has been used.
