Enhancement of underwater images and videos is an important task required in several image-based applications like survey, seafloor mapping, telepresence, documentation etc. Color correction or white balance of underwater images is the most challenging issue because of the highly-variable illumination conditions, increasing bluish shift with the depth. Another problem is the low image contrast with...
Multispectral imaging techniques are widely used to analyse and restore digital images of ancient documents degraded over time. In particular, acquisitions in infrared and ultraviolet bands can reveal information invisible by naked eye, which is not captured by conventional RGB imaging. Multispectral acquisitions are usually performed with filter-wheel cameras that mount a series of interference filters...
