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.
