Efficient Multispectral Facial Capture With Monochrome Cameras [PDF]
Color and Imaging Conference, 2018 We propose a variant to polarized gradient illumination facial scanning which uses monochrome instead of color cameras to achieve more efficient and higher-resolution results. In typical polarized gradient facial scanning, sub-millimeter geometric detail is acquired by photographing the subject in eight or more polarized spherical gradient lighting ...

SEAMLESS CO-REGISTRATION OF IMAGES FROM MULTI-SENSOR MULTISPECTRAL CAMERAS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 Small-format, consumer-grade multi-camera multispectral systems have gained popularity in recent years. This is specifically due to the simplicity of their integration onboard platforms with limited payload capacity, such as Unmanned Aerial Vehicles ...

Geometric Multispectral Camera Calibration [PDF]
, 2009 A large number of multispectral cameras uses optical bandpass filters to divide the electromagnetic spectrum into passbands. If the filters are placed between the sensor and the lens, the different thicknesses, refraction indices and tilt angles of the filters cause image distortions, which are different for each spectral passband.

Optics Express, 2014 A multispectral imaging technique with a new CMOS camera is proposed. With a four channel Bayer patterns, the camera can acquire four spectral images simultaneously. We have developed a color correction process to obtain accurate color information, and we have also demonstrated its applications on portrait enhancement, shadow removal, and vein ...

Multispectral camera with sequential imaging. [PDF]
Journal of Radio Electronics, 2021 The paper proposes the implementation of a multispectral camera based on a digital video camera and a set of interference filters, which provides the formation of a sequential stream of spectral images. The results of verification of the generated spectral images are presented.

Camera response function assessment in multispectral HDR imaging
Electronic Imaging, 2022 Multispectral imaging techniques improve the accuracy of spectral reconstruction as well as color measurement in image-based data capture systems compared to the conventional RGB cameras. On the other hand, high dynamic range imaging provides recording a higher range of scene radiance values when the dynamic range of the camera does not cover values ...
