Two effective and computationally efficient pure-pixel based algorithms for hyperspectral endmember extraction
Endmember extraction is of prime importance in the process of hyperspectral unmixing so as to study the mineral composition of a landscape from its hyperspectral observations. Tho...

Driver risk evaluation based on acceleration, deceleration, and steering behavior
We propose a driver risk evaluation method based on the analysis of driving data captured with drive recorders. To evaluate the acceleration behavior of each driver we plot the ma...
