A new hyperspectral dataset and some challenges

摘要

We present a new hyperspectral data set that FOI will keep publicly available. The hyperspectral data set was collected inan airborne measurement over the countryside. The spectral resolution was about 10 nm which allowed registrations in 60spectral bands in the visual and near infrared range (390-960 nm). Objects with various signature properties were placedin three areas: the edge of a wood, an open field and a rough open terrain, Several overflights were performed over the areas. Between the overflights some of the objects were moved, representing different scenarios. Our interest is primarilyin anomaly detection of man-made objects placed in nature where no such objects are expected. The objects in the trialwere military and civilian vehicles, boards of different size and a camouflage net. The size of the boards range from mul-tipixel to subpixel size. Due to wind and cloud conditions the stability and the flight height of the airplane vary betweenthe overflights, which makes the analysis extra challenging.
