While traditional image and video processing focus on extracting knowledge from data of a single modality, such as visual spectrum or thermal infrared video, this report investigates the benefits and challenges of capturing and analysing multimodal video. It specifically targets the two modalities of visible spectrum and thermal infrared video. A novel capture device has been developed to captu...

The requirements on sunscreens have essentially changed, since some years ago it was demonstrated that approximately 50% of free radicals, that are formed in the skin by solar radiation, originate from the visible and infrared regions of the solar spectrum. In addition, a critical radical concentration threshold could be found. If this concentration, the free radical threshold value (FRTV), is ...

The SOLar SPECtrum (SOLSPEC) and the SOlar SPectrum (SOSP) spectrometers are two twin instruments built to carry out solar spectral irradiance measurements. They are made of three spectrometers dedicated to observations in the ultraviolet, visible and infrared domains. SOLSPEC flew with the ATmospheric Laboratory for Applications and Science (ATLAS) while SOSP flew on the EUropean Retrieval CAr...

In an earlier paper (1) it was reported that etiolated barley seedlings when exposed to visible radiation suffer a large decrease in catalase activity and a simultaneous increase in chlorophyll. Eyster (4) found that dark-grown genetic albino corn seedlings, completely devoid of chlorophyll, also suffer a loss in catalase activity when illuminated. There are several earlier studies such as Knot...
