Computationally Efficient Target Classification in Multispectral Image Data with Deep Neural Networks [article]

Lukas Cavigelli, Dominic Bernath, Michele Magno, Luca Benini
2016 arXiv   pre-print
Detecting and classifying targets in video streams from surveillance cameras is a cumbersome, error-prone and expensive task. Often, the incurred costs are prohibitive for real-time monitoring.  ...  We combine an RGB camera with a 25-channel VIS-NIR snapshot sensor to assess the potential of multispectral image data for target classification.  ...  It provides 25 equally-spaced spectral bands with center frequencies in the range of 600-975 nm and can stream multispectral cubes at up to 170 frame/s over USB 3.  ...
