Description
Summary:There are situations where it is not possible to capture a large document with a given imaging media such as Scanner and Xerox machine in a single stretch because of their inherent limitations. This result in capturing a large document in terms of split components of an image. Hence, the need is to mosaic the split components into a large document image. In this paper, we present a new and simple approach to mosaic the two split images of a large document based on matching sum of values of pixels of window in the split images. The method compares the sum of values of pixels of window in split images to identify Overlapping Region (OLR) in the split images. The OLR, a region in common, helps in mosaicing of two split images of large document. However, a small OLR is assumed to be available at the end of split images of a large document. In addition to this, the OLR in the split images depends on the size of the window. Experimental results show that the performance of the proposed method is satisfactorily.
