INTRODUCTION
Many problems require finding the coordinate transformation between two images of the same
scene or object. One of them is Image Mosaicing. It is important to have a precise description of
the coordinate transformation between a pair of images. Image mosaics are collection of
overlapping images together with coordinate transformations that relate the different image
coordinate systems. By applying the appropriate transformations via a warping operation and
merging the overlapping regions of a warped images, it is possible to construct a single image
covering the entire visible area of the scene. This merged single image is the motivation for the
term ``mosaic''.
Image mosaics allow one to compensate for differences in viewing geometry. Thus they can be
used to simplify version tasks by simulating the condition in which the scene is viewed from a
fixed position with single camera. Mosaic are therefore quite useful in tasks involving motion or
change detection or determining the relative pose of the new images that are acquired. They can
be used to determine what parts of the scene visible from that point have been observed.
