Dual tree complex wavelet transform based denoising of optical microscopy images
(Optical Soc Amer, 2012)Photon shot noise is the main noise source of optical microscopy images and can be modeled by a Poisson process. Several discrete wavelet transform based methods have been proposed in the literature for denoising images ... -
Non-contact estimation of heart rate and oxygen saturation using ambient light
(Optical Soc Amer, 2015)We propose a robust method for automated computation of heart rate (HR) from digital color video recordings of the human face. In order to extract photoplethysmographic signals, two orthogonal vectors of RGB color space ... -
Reflective light modulator based on epsilon-GaSe crystal
(Optical Soc Amer, 2002)We report the results of investigating a low-voltage, polarization-insensitive, reflective-type modulator based on an epsilon -GaSe crystal and operated at the 1.960-eV line of a He-Ne laser. We demonstrate that the ...
