Adaptive image interpolation for full-field digital x-ray mammography.
Some full-field digital x-ray mammography systems use multiple abutted two-dimensional detectors. Gaps between adjacent detectors produce seams in the composite image. We develop an adaptive linear interpolation method for estimation of missing data in the seams. In this method, the interpolation path is determined on the basis of the similarity between adjacent subimage boundary profiles. In experiments with phantom images and clinical mammograms, the adaptive method performed significantly better than the conventional linear interpolation.
