Abstract

The paper presents a new method for enhancement of orthodontic images using the combination of two-dimensional data with different type of illumination and their processing using digital de-nosing and gradient image enhancement in the preliminary stage. The region growing method and the appropriate seed selection is then studied as an alternative to the distance and watershed transforms for their segmentation. The main goal of the paper is in (i) the presentation of mathematical methods for image analysis in the orthodontic treatment and (ii) presentation of the region growing method use for image regions classification. Resulting algorithms are used for gradient edge detection and image components enhancement in orthodontics.
