Abstract

Dental hard tissue registration is very challenging due to the complexity of histological structure, the variability of imaging modality and image quality. To benefit from the advantages of the relative works, this paper proposed a novel dental hard tissue auto-registration method based on multi-modality dental images. It employed the modified ICP algorithm and was especially effective for dental fluorescence imaging and the reflectance imaging. The algorithm firstly pre-processed the dental images to decrease the impact of imbalance local illumination. Secondly, it investigated a robust feature points extraction stra-tegy, i. e. calculated the boundaries of hard tissue as initial feature point sets, and further extracted the lesion areas based on the prior knowledge of oral histopathology for the refinement of feature points. Finally, this paper executed the modified ICP algorithm on the basis of the ICP iterative method and robust loss function to register dental image. The experimental results show that the proposed method is not only robust, but also can converge more quickly and achieve higher accuracy.
