Abstract
This invention relates to an improved apparatus and method for in vivo monitoring of visually accessible surfaces of the body. The invention synthesizes methods of systems identification and computer vision to quantify and/or classify features of surface or subsurface anatomic, physiologic, or pathologic structures or processes. Such is accomplished by the stimulation of anatomic surfaces with light (visible, infrared, and/or ultraviolet, structured or uniform), followed by the quantitative analysis of digital images (multiresolution, multiview, and/or multispectral) of reflected or emitted light from the surface of interest.
