CIRCULAR MOIRE PATTERNS IN 3D COMPUTER VISION APPLICATION

Abstract

Geometric patterns generated by superimposing two identical random dot images are an interesting phenomenon that has drawn attention of researchers for many [2, 3, 4, 5]. One of those patterns that shows the circular rings when two random dot images are overlaid one on top of another is investigated in this research including its applications in three dimensional computer vision. Two practical applications of the Moiré rings have been explored. These are depth-perception application and similarity measurement application. Experiments using artificially generated random dot images and real images taken using an image capturing device such as a camera or a scanner and converted to pseudo-random dot representation has been conducted successfully.
