There are some situations where it is not possible to capture or scan a large document with
given imaging media such as scanner or Xerox machine as a single image in a single
exposure because of their inherent limitations. This results in capturing or scanning a large
document image into number of split components of a document. Hence, there is a need to
mosaic the several split components into a single large document image.
In this work, we present a novel and simple approach for mosaicing the two split document
images using wavelet decomposition to generate single and large document image. The
proposed method uses the wavelet decomposition to speed up the mosaicing process by
means of Multi Resolution Analysis (MRA). The pixel based and Column –Block matching
procedures are used here to identify the overlapping region in the split images. The
overlapping region is a common region which helps in obtaining mosaiced image from its
split images. The proposed methods work based on assumption that the overlapping region
is present at the right end of split image1 and at the left end of split image2 |
