An adaptive enhancement means adapt to CR medicine image
Minghui Zhang, Yaoyu Zhang · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2010
It puts forward CR medicine image adaptive enhancement arithmetic based on the ratio of image variance to noise variance which can adjust factor K bases on CR image gray characteristic and enhance image detail and improve image diagnosis value. Experiment results demonstrate that the algorithm enhances CR image detail and the value of DV/BV was higher than the other algorithms, moreover CR image enhanced has good visual effect, the method is fit for edge detail enhancement of CR medicine radiation image.
