Automatic Seamless Image Mosaicing: An Approach Based on Quad-tree Technique
M. Ravishankar · 2010
In real-life situations, the field of view of the imaging devices is usually smaller than the scene to be imaged, due to the inherent limitations. Even if the whole scene is captured in a single exposure, it could result in an image having poor resolution. In such circumstances, it will never be possible to capture the scene as a single image for further processing or human inspection. The only solution to such a problem is to capture the scene by splitting the scene into adjacently placed multiple frames. This process warrants a post imaging operation that requires cohering of these small images to create a single image. In this paper, a new approach is used to create a single large image by adopting a quad-tree approach, where the image is decomposed into sub images to find the corresponding points in the sub images and thereby reducing the search space. The proposed algorithm reduces the search space to a greater extent for finding correspondence between the split images where the complexity reduces to the order of ) 1 ) 3 ( (log 2 4 n
