RT Journal Article T1 Fringe pattern denoising by image dimensionality reduction A1 Quiroga Mellado, Juan Antonio A1 Vargas Balbuena, Javier A1 Estrada, Julio César A1 Carazo García, José María A1 Sánchez Sorzano, Carlos Óscar AB Noise is a key problem in fringe pattern processing, especially in single frame demodulation of interferograms. In this work, we propose to filter the pattern noise using a straightforward, fast and easy to implement denoising method, which is based on a dimensionality reduction approach, in the sense of image rank reduction. The proposed technique has been applied to simulated and experimental ESPI interferograms obtaining satisfactory results. PB Elsevier Sci. Ltd.
