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.
Claims15
An apparatus for monitoring visually accessible surfaces of the body comprising:
- means for acquiring digital images;
- means for pre-processing said digital image to calibrate and correct for aberrations in the digital image;
- means for determining or estimating a three-dimensional representation of the surface of which the image is taken;
- means for estimating the boundaries of lesions on said surface from said image;
- means for extracting two- and three-dimensional quantitative features of the lesions on said surface from said image;
- means for visual display and hardcopy presentation of two- dimensional and reconstructed three-dimensional representations of the lesions on said surface;
- means for storing said digital images in a database;
- and
- means for extracting information from the database for comparison of images at different points in time or space.
