Abstract

This paper proposes a novel, fully automatic method for composing mosaic images in Computed Radiography. The method combines the detection of white-band edges with a cross- correlation technique. The white-band edges are positions of overlap lines. Several new kinds of measurements are proposed to evaluate the likelihood of a position to be a white-band edge. Multiple checks are used to reject less likely candidates. An error measure is defined for picking up the most likely candidates. The white-band candidate positions are fed to a cross-correlation method to compute the final alignment parameters for mosaic composition.
