Multiscale Entropy Study of Medical Laser Speckle Contrast Images

IEEE Transactions on Biomedical Engineering, 2013
Laser speckle contrast imaging (LSCI) is a noninvasive full-field optical imaging technique that gives a 2-D microcirculatory blood flow map of tissue. Due to novelty of commercial laser speckle contrast imagers, image processing of LSCI data is new. By opposition, the numerous signal processing works of laser Doppler flowmetry (LDF) data-that give a 1-

Noise Model for Laser Speckle Contrast Imaging

Biomedical Optics, 2006
We have developed a noise model for laser speckle contrast imaging. Its dependence on the sliding window size, exposure time, beta, and correlation time is revealed. The accuracy of the model is tested with experiments.

The contrast of femtosecond laser speckles in the image plane

SPIE Proceedings, 2005
We put forward the concept of femtosecond laser speckles and studied twelve speckle patterns produced by four aluminium sheets with different surface roughness under illumination of three laser sources of one continuous wave laser and two other femtosecond pulsed lasers with FWHM widths of 36fs and 12fs, respectively. The femtosecond laser speckles are

Noise analysis in laser speckle contrast imaging

SPIE Proceedings, 2010
Laser speckle contrast imaging (LSCI) is becoming an established method for full-field imaging of blood flow dynamics in animal models. A reliable quantitative model with comprehensive noise analysis is necessary to fully utilize this technique in biomedical applications and clinical trials.
