Processing Procedure

Image processing procedure for noise reduction and image registration in the PSP experiments is investigated. A few kinds of filter are examined for the shot noise reduction caused by the CCD camera. The algorithm to detect a marker cell located on the model surface is proposed and an appropriate number size is shown. The algorithm using the wavelet transform is investigated to sharpen the edge around the model. The results indicate that the method developed in this paper effectively removes the shot noise and corrects the displacement of the model during wind-on.
