This paper presents a novel image fusion system for multisensor and multiband remote sensing data with an objective to synthesize an image which is either not feasible or not economical to obtain from single remote sensing satellite image. The fusion system focuses on objective, selection of data, pre-processing, registration, and fusion methodology with results. The paper also emphasizes on understanding of physics of remote sensing for meeting the objective as well as for success of fusion. In view of availability and archival of huge amount of remote sensing imagery from several satellites, different combinations for fusion from multisensor and multiband images are proposed. Due to use of images with differing modalities, resolution, and time of acquisition for fusion, a generalized and robust image registration methodology is adopted. Appropriate fusion methodologies are proposed for different fusion combinations and their results are illustrated and compared.
