Combined denoising filter for fringe pattern in electronic speckle shearing pattern interferometry

“…2(c) shows the effectiveness of our proposed denoiding method. In agreement with the simulation fringe, the experimental fringe pattern obtained by electric speckle shearing pattern interferometer [22] is also used to test the performance of CF. The denoised images are shown in Fig.4, where Fig.4 (a) shows the experimental fringe pattern.…”
