摘要：
A method for identification of caries, executed at least in part on data processing hardware, obtains an original digital tooth image that has a plurality of color channels and generates an adjusted image by adjusting intensity values of the original digital tooth image to a range between a minimum value and a maximum value, wherein the adjusted image has at least a green channel image Iwgreen, a red channel image Iwred, and a blue channel image Iwblue. One or more tooth regions are segmented from gum and background regions within the adjusted image according to a relationship between two or more of the images Iwgreen, Iwred, and Iwblue to each other. One or more caries lesions is identified according to pixel intensity values from within the one or more segmented tooth regions, and the one or more tooth regions and the displayed and identified caries regions are highlighted.
