 storical artefacts - Cerys Jones (UCL)

DESCRIPTION:Multispectral imaging of historical artefacts can reveal lost 
 text and drawings that have not been seen for hundreds and even thousands 
 of years. It involves capturing images of an object illuminated in ultravi
 olet\, visible and infrared light to uncover features that cannot be detec
 ted by the human eye alone. Filters can also be placed in front of the cam
 era lens to extract the fluorescence from the object. Typically between 15
 -20 images are captured\, where each image represents a different waveleng
 th and filter combination. In this talk\, I will present on the current im
 age processing techniques that are commonly applied to multispectral image
 s of historical artefacts and show examples of my results on a variety of 
 artefacts including Ancient Egyptian coffins\, research letters from Profe
 ssor Karl Pearson\, and more.
