Remote Sensing, 2021 Salt marsh evolution is strongly affected by tidal processes and ecology, which regulate sediment accretion and erosional rates. A balance between marsh erosion and deposition in a restored tidal wetland is crucial for analyzing restoration strategies to

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.

Multispectral curved compound eye camera
Optics Express, 2020 In this work, we propose a new type of multispectral imaging system, named multispectral curved compound eye camera (MCCEC). The so called MCCEC consists of three subsystems, a curved micro-lens array integrated with selected narrow-band optical filters, an optical transformation subsystem, and the data processing unit with an image sensor.

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 ...

Selecting the geology filter wavelengths for the ExoMars Panoramic Camera instrument [PDF]
, 2012 The Panoramic Camera (PanCam) instrument will provide surface remote sensing data for the ExoMars mission. A combination of wide-angle stereo, multispectral, and high resolution imagery will generate contextual geological information to help inform which

UAV-BASED RIVER PLASTIC DETECTION WITH A MULTISPECTRAL CAMERA
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 . Plastic is the third world’s most produced material by industry (after concrete and steel), but people recycle only 9% of plastic that they have used.

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 ...
