International audience; We introduce a low-complexity codec for lossy compression of hyperspectral images. These images have two kinds of redundancies: 1) spatial; and 2) spectral. Our coder is based on a compression scheme consisting in applying a 2

In previous works, we defined the Optimal Transform Code (OTC) assuming high rate coding and using the asymptotical Bennett approximation of the rate. We showed that the OTC gives the optimal linear transform of a multicomponent image compression sch

The system makes it possible to detect a vehicle on a road and provide two-way communication between the vehicle (4) and a fixed assembly attached to the road, the fixed assembly (1, 6, 7) being capable of communicating via electromagnetic waves with
