Estimating Measurements of Craniofacial Structures in Dental Radiographs

A data processing system comprising:

• a processor;
• and
• a memory in communication with the processor, the memory comprising executable instructions that, when executed by, the processor, cause the data processing system to perform functions of:
• receiving a dental radiographic image that includes an oral structure;
• selecting a segmenter and an object detector;
• predicting masks and points of the oral structure using the segmenter and the object detector;
• providing image metadata comprising the masks and points and the dental radiographic image to a selector;
• selecting by the selector at least one measurement method of a set of measurement methods according to the dental radiographic image and the image metadata;
• calculating a sensor pixel to mm (millimeter) ratio using the measurement method;
• and
• calculating a calibrated measurement of the oral structure using the sensor pixel to mm ratio and the image metadata.
