A camera for simultaneously capturing a visible and near-infrared (NIR) image of one or more objects, the camera comprising: at least one colour filter array (CFA) including at least four different filters, said at least one colour filter array having visi ...
We present a method to automatically detect shadows in a fast and accurate manner by employing the inherent sensitivity of digital camera sensors to the near-infrared (NIR) part of the spectrum. Shadows are generally found in the dark parts of an image, be ...
Shadows, due to their prevalence in natural images, are a long studied phenomenon in digital photography and computer vision. Indeed, their presence can be a hindrance for a number of algorithms; accurate detection (and sometimes subsequent removal) of sha ...
Standard digital cameras are sensitive to radiation in the near-infrared domain, but this additional cue is in general discarded. In this paper, we consider the scene categorisation problem in the context of images where both standard visible RGB channels ...
The research proposal describes the spectroscopic technique to study the intermediate state of protonated peptides formed after the UV excitation. It was shown previously that with the assistance of the CO2 laser the side chain loss fragmentation was enhan ...
Near-infrared light can be used to determine the optical properties (absorption and scattering) of human tissue. Optical tomography uses this principle to image the internal structure of parts of the body by measuring the light that is scattered in the tis ...
We demonstrate the first 10Gb/s parametric transmitter in short-wave Infrared band. The device operates by converting 1278nm signal over 85THz to generate channel at 2002nm using highly-nonlinear-fiber and was characterized by error-free performance. ...
Skin tones, portraits in particular, are of critical importance in photography and video, but a number of factors, such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles can reduce their appeal. Moreover, such “defe ...
The main topic of this thesis is the fabrication and characterization of structures smaller than the wavelength of light, for operation in the visible or near infrared spectral range. In the first part of this thesis, the fabrication of periodic structures ...
Selective multi-gas detection is often based on spectroscopic methods in the infrared region. The resulting setup consists of a spectrometer and the probing setup where often the spectrometer makes the sensing device large and heavy and does not allow easy ...
