Abstract
A method is disclosed for processing of images to detect dental caries, that includes the following steps. Directing incident light () toward a tooth (), where this light excites a fluorescent emission from the tooth. Obtaining a fluorescence image () from the fluorescent light component (), and obtaining a reflectance image () from the back-scattered light () from the tooth. Applying a color balance operation to the reflectance image. Removing the specular reflectance components from the color balanced reflectance image () to give a back-scattered reflectance image (). Registering the fluorescent image with the back-scattered reflectance image. Combining the registered fluorescent image () with the back-scattered reflectance image to provide a diagnostic image ().
