Paper Abstract

In this paper, we investigate the application of the EMD to automatically reduce speckles on the fringe pattern. It is found that the number of the removed intrinsic mode functions (IMFs) is sensitive to the period of the fringe pattern, but not sensitive to the speckle size and the speckle amplitude. Thus, a database system based on statistic simulations for finding the optimization of removing speckles is built. With this database, more than 80% speckles on the fringe pattern can be robotically reduced.
