An open system to generate hyperspectral cubes for skin optical reflectance analysis
International audience; Optical visible light analysis of the skin mainly relies on RGB colour imaging. Multispectral imaging of human skin represents a more accurate approach for in vivo analysis of its optical properties. Few dermatology-oriented multispectral devices have been hitherto developed. Their diagnostic abilities for pigmentary tumors or other clinical applications are still being evaluated [1]. We have developed a multispectral imaging system for in-vivo skin optical analysis. It is based on a charge-coupled device camera, a rotating wheel with a set of seven interference filters and a computer. All interference filters were chosen specifically to cover the visible spectrum ra…
Development of an imaging system dedicated to the acquisition analysis and multispectral characterisation of skin lesion
Visual evaluation of cutaneous lesions is the analysis the most commonly performedby dermatologists. This diagnostic is mainly done by naked eye and is based on criterionsuch as the size, shape, symmetry but principally on colour of the lesions. However, thisanalysis is subjective because it depends on the practician experience and the acquisitionconditions. We propose in this dissertation (1) the development of a multispectralcamera specifically dedicated for dermatological use. This device is based on a filterwheel composed of interferential filters and a neural network-based algorithm, generatinga hyperspectral cube of cutaneous data. This setting combines advantage of both spectrophotom…
