Modélisation surfacique et volumique de la peau : classification et analyse couleur

Abstract : Thanks to recent developments, skin evaluation has become easier and more accurate. Topographical evaluation of skin surface by fringes projection as intra-dermal structures and exploration by in-vivo laser confocal microscopy are some examples. The use and development of these tools are developed in this thesis. Image processing contribution is obvious, as much for the treatment of these tools acquisitions, as for cutaneous parameters evaluation, based on digital camera acquisitions for example. Grey level LIP model extension to color has been realized in order to bring way of analysis near to the expert one, thanks to logarithmic bases of this model, very close to the human vision. At least, data clustering in images, a redundant topic in image analysis, has been approached by ascending hierarchical clustering, using rigorous mathematical properties thanks to the ultrametric distances
