摘要： A method for intraoral imaging obtains a digital image of one or more teeth and detects first and second boundaries. At each of the first and second boundaries, there is calculated a boundary ratio of mean gray-scale values for the tooth area on one side of the boundary to mean gray-scale values for background areas on the other side. The calculated boundary ratios are stored. A third ratio of the mean gray-scale values for the tooth area near the first boundary to the mean gray-scale values for the tooth area near the second boundary is calculated and stored. A vector is formed and stored that contains at least the calculated boundary ratios and the third ratio. The tooth surface is classified as either smooth or occlusal according to the stored vector. The image data is processed according to the classification and processing results are reported.

摘要： A method for identification of caries, executed at least in part on data processing hardware, captures a plurality of blocks of digital tooth images, each block of tooth images comprising a fluorescence image and one or more reflectance images. At least one registered fluorescence image is generated from the fluorescence image and the one or more reflectance images. A combined image is generated using each of the one or more reflectance images and the at least one registered fluorescence image.
