Method for quantifying caries |
摘要 |
Method and/or apparatus embodiments for automatically identifying caries, executed at least in part on data processing hardware, can acquire, multiple reflectance images of a tooth, wherein each reflectance image includes at least red, green, and blue intensity values for a region of pixels corresponding to the tooth. Each reflectance image in the plurality of reflectance images is processed by (i) defining a tooth region within the reflectance image; and (ii) identifying caries within the defined tooth region for each reflectance image. The reflectance images are registered and the registered processed images are combined to form a result image that shows the identified caries. In one embodiment, multiple reflectance images of a tooth are taken from substantially the same camera position. |

1. A method for automatically identifying caries, executed at least in part on data processing hardware, the method comprising:
acquiring, from substantially the same camera position, a plurality of reflectance images of a tooth, wherein each reflectance image includes at least red, green, and blue intensity values for a region of pixels corresponding to the tooth; processing each reflectance image in the plurality of reflectance images by:
(i) defining a tooth region within the reflectance image; and(ii) identifying caries within the defined tooth region for each reflectance image; registering the plurality of reflectance images; and combining the registered plurality of processed images to form a result image that shows the identified caries. |
