Study of automatic digital video image processing for real-time holographic interferometry |
| |
| Abstract: | An automatic digital video image processing software for analysis of the real time holographic interference fringe was developed. The Delphi visual software development platform was used and windows API was adopted to get the pray value of the random positions that the mouse clicked on. A neighborhood field average filtering method is adopted to eliminate the image's noise, and the average smoothness curve's method was used to smooth the curve of gray value varied with time. The curve of the pray value varied with time and the curves of out of plane displacement varied with time were drawn automatically. The dynamic digital processing techniques were discussed. |
