Image processing Imaging with hyperspectral sensors: optimum design for your application

Colour cameras extract information based on the three standard colour channels; red, green and blue. This colour reproduction technique is an approximation and it is often insufficient to reliably solve a given machine vision problem. Hyperspectral imaging overcomes this limitation by providing a greater number of spectral bands. Thanks to the recent advances in sensor design, the required narrow-band spectral filters can now be implemented at the sensor level.
