The characteristic of digital CR medicine radiation image has wide dynamic range
abundant details and bad contrast
so it is necessary to enhance CR image to the need of doctor diagnosis. But the general enhancement algorithms don't consider human visual characteristics
so it puts forward CR medicine image adaptive enhancement algorithm combining the human visual property
which is more sensitive to smooth area noise compared with detail area noise
and makes image edge detail enhancement great in detail area
and detail enhancement little in smooth area
in which factor K is based on space change of image domain
accordingly gaining non-linear enhancement edge details of CR image. Experiment results demonstrate that the algorithm enhances CR image detail and CR image enhanced has good visual effect
so the method is fit for edge detail enhancement of CR medicine radiation image. 2010 IEEE.
