In this study, a novel adaptive
speckle noise reduction algorithm using anisotropic diffusion filter based on Haar wavelet transform and the median absolute deviation was proposed.
Cuando la fibra es perturbada, se asume que los cambios en el patron de
speckle se deben principalmente a cambios de fase y que la intensidad total del patron de
speckle en la fibra es constante (Dario Gomez & Gomez, 2013).
In this paper examined about the
speckle noise model, the proposed NDWT algorithm for
speckle suppression in SAR imagery and results and discussion of proposed methodology.
After that, we can get the
speckle by performing the fast Fourier transform of the resulting matrix.
Evaluation of systemic microvascular endothelial function using laser
speckle contrast imaging.
We have shown above that the problem of finding
speckle intensity distribution for wave propagation in inhomogeneous media can be mapped to the problem of mixing in incompressible flows.
They used a miniature high-speed camera to record the fluctuating
speckle pattern.
It has been applied to measure the transient phenomena by moire interferometry [35] and
speckle interferometry.

Speckle in ultrasound B-mode scans," IEEE Transactions on Sonics and Ultrasonics, vol.
Although the light scattering method has discovered applications in the characterizations of the dynamic laser
speckle from a magnet fluibuiltd [13,14], the contrast of the
speckle or the scattering intensity may open only a general observation to the bulk magnet solution.
Classical despeckling methods such Lee [11], Frost [12] and Gamma-MAP [13] use a priori statistical information of
speckle noise.
Two-dimensional
speckle tracking echocardiography (STE) allows the study of regional myocardial deformation expressed by strain and strain rate.
