Paper Abstract

This paper will report on the methods of compound regions average (CRA) and the adaptive visual primitive elements matched (AWE). By CRA method, the high frequency noise of the digital speckle pattern interference (DSPI) fringe could be filtered. Further. the directions of the fringes were determined with AVPE method and the fringe skeleton could be obtained accurately by directional derivative. Results are presented for center determination from DSP! fringe patterns.
