A Phase-Based Image Registration Algorithm for Dental Radiograph Identification
Dental radiographs have been used for the accurate assessment and treatment of dental diseases. For an accurate diagnosis, the complete geometric registration between radiographs is required. The perspective projection between two radiographs may be observed, even if they are taken from the same oral regions of the subject. This paper presents an efficient dental radiograph registration algorithm using Phase-Only Correlation (POC) function. The use of phase components in 2D (two-dimensional) discrete Fourier transforms of dental radiograph images makes possible to achieve highly robust image registration and recognition. Experimental evaluation using a dental radiograph database indicates that the proposed algorithm exhibits efficient recognition performance even for distorted radiographs.
