Mosaicing is blending together of several arbitrarily shaped images to form one large radiometrically balanced image so that the boundaries between the original images are not seen. Any number of geocoded images can be blended together along user-specified cut lines. These techniques can be used to build environments and 3-D models for virtual reality application based on recreating a true scene, i.e., tele-reality applications. The fundamental technique used in this project is image mosaicing, i.e. the automatic alignment of multiple images into larger aggregates which are then used to represent portions of a 3-D scene.
