Automatic adaptive contrast enhancement for radiological imaging

Enhancement of radiological images can improve their subsequent clinical interpretation or improve their automatic screening. Two new algorithms for automated adaptive contrast enhancement are presented. Compared to existing techniques, the proposed methods are completely automatic, in the sense that they do not require any interactive iterative adjustments by the reviewing physician. They exhibit better or equal performance with available methods. Both algorithms can be efficiently implemented using low-cost workstations or personal computers and can process even 2K /spl times/ 2K images in a few seconds.<>
