title: Short communication: charge-coupled device camera optical density range enhancement and the effect on radiographic image segmentation.
abstract: A method is presented for the pre-processing of radiographs in the automated determination of skeletal maturity. By linearly combining several source images, a density range enhancement is obtained without the creation of edge artefacts. An increase of bit depth of 1 bit was obtained, and density range was improved by 1 OD.
