Image mosaicing

Mosaicing is one of the techniques of image processing which is useful for tiling digital images. 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 (polygons). Mosaicing is a special case of geometric correction where registration takes place in the existing image. If ground control points (GCP) are collected the input image is transformed according to the derived polynomial into the output image. If no GCPs are provided, but both images already have compatible georeferencing, then an appropriate translation and scaling will be applied instead of polynomial transformation. This technique is generally used on several images like remote sensed images, bio-medical images or other digital images. This paper attempts to develop a package for mosaicing multiple images. The work has been divided into three modules. Each module is run independently. These modules are (1) Images are displayed in overview, full resolution/zoomed modes, (2) Registration and layout file generation, (3) Polygon filling, blending and displaying of mosaiced images. These modules can be integrated to form a full-fledged system
