Multispectral imaging with a modified DSLR camera
2016 International Symposium on Electronics and Smart Devices (ISESD), 2016This paper describes a multispectral imaging system using a Canon EOS 1000D camera, photographic lenses, and a dispersive element. The system consists of three subsystems: a PVC holder to arrange the optical devices that can be connected to the camera, an acrylic frame to support the position of the PVC holder, and expectation maximization algorithm to

An efficient compression method for one-shot multispectral camera
2012 Picture Coding Symposium, 2012Many RGB digital cameras use a Bayer color filter array. In these cameras a full-resolution image is obtained from a mosaicked image by interpolation, and then the full resolution image is encoded. Similarly, mosaicked color filter arrays and interpolation methods for multispectral images have been proposed in recent years.

Miniature multispectral camera and its application in machine vision
2016 IEEE International Conference on Information and Automation (ICIA), 2016This paper presents a miniature multispectral camera and its application in machine vision. Differ to conventional camera, the multispectral camera can capture image with high spectral resolution. First, the design of the multispectral camera is introduced. It consists of a Digital Micro-mirror Device (DMD) sandwiched by two optic gratings.

MADCam: The multispectral active decomposition camera
2001A real-time spectral decomposition of streaming three-band image data is obtained by applying linear transformations. The Principal Components (PC), the Maximum Autocorrelation Factors (MAF), and the Maximum Noise Fraction (MNF) transforms are applied. In the presented case study the PC transform appears to provide the best result for separating signal
