The main objective of the proposed software solution is to improve the performance in dental diagnosis using infrared lock-in thermography and complex image processing algorithms for the determination of defective zones of teeth.
The recorded amplitude profile of the thermal wave shows a maximum corresponding to a heat accumulation in the region where the open micro-gap is found, whereas a minimum in the phase profile is detected. These maxima/minima are convenient indicators that allow to locate surface breaking defects on teeth. For the purpose of emphasizing very small temperature variations surrounding the thin flaws, different image processing algorithms were developed and included within the DCD software solution.

Features
- Upload phase and amplitude IR images of teeth
- Anisotropic diffusion, morphological operators, adaptive image enhancement, edge detection
- Plot the teeth defective zones due to marginal and internal micro-gaps located at the interface between tooth and filling.
