Fringe analysis has been at the forefront of research due to its ubiquity in many optical
measurement techniques such as electronic speckle interferometry, shearography, and …

Rapid urbanization has already caused many impacts, such as environmental degradation
and imbalanced resource allocation. As the frontiers of urbanization, urban fringe areas …

A simultaneous phase-shifting dual-wavelength interferometry based on two-step
demodulation algorithm is proposed in this Letter. First, two lasers with different wavelengths …

By virtue of the anti-noise and anti-defect abilities, in this paper, a two-dimensional
continuous wavelet transform algorithm is proposed to analyze two-step arbitrarily phase …

Filtering off speckle noise from a fringe image is one of the key tasks in electronic speckle
pattern interferometry (ESPI). In general, ESPI fringe images can be divided into three …

Denoising of electronic speckle pattern interferometry (ESPI) fringe patterns with variable
density is challenging. In this paper, we present a method to denoise ESPI fringe patterns …

In this paper, it is proposed a gaussian convolution-based fringe pattern denoising method.
As will be shown, this method is robust enough compared with some of the most outstanding …

In the paper, we propose a generalized deep nonlinear CNN model, named as MDD-Net, for
filtering various kinds of ESPI fringe patterns with structure protection and shape …

It is a key step to remove the massive speckle noise in electronic speckle pattern
interferometry (ESPI) fringe patterns. In the spatial-domain filtering methods, oriented partial …

Fringe pattern denoising is of prime importance in phase demodulation, especially for a
single fringe pattern in speckle interferometry. A fringe speckle noise removal algorithm …
