Abstract

We present a database system based on the empirical mode decomposition (EMD) to automatically reduce the speckle in a fringe pattern. With reference to the database, speckles on the fringe pattern can be efficiently and robotically reduced. Percentage of the removed speckles can be predicted as well.
