METHOD FOR AUTOMATIC ARRANGEMENT DETERMINATION OF PARTIAL RADIATION IMAGES FOR RECONSTRUCTING A STITCHED FULL IMAGE

A method for automatic arrangement determination of partial radiation images for reconstructing a stitched full image. At least two radiation sub-images of an elongated object are acquired and converted to digital images. A hypothesis list is constructed and overlap regions for consecutive sub-images pair in each hypothesis are detected. A plurality of different measurements are conducted on consecutive sub-image pair of each hypothesis. The correlation function is calculated to find the function maximum and the horizontal displacement between the sub-image pair. The magnitude of the horizontal displacement is checked and an overall figure-of-merit is established. The hypothesis of maximum figure-of-merit for best candidate is selected. The sub-images are processed based on selected hypothesis for stitching to produce an output image.
