ABSTRACT:
FIELD OF THE INVENTION
The field of the invention is the field of automatic machine vision and classification, in particular to the field of classification of biological tissue from images of the biological tissue.
BACKGROUND OF THE INVENTION
The background of the invention is covered in great detail in the above identified copending applications, which are included by reference. Not included in the above references are references to conducting light from place to place so that the image is conserved.
OBJECTS OF THE INVENTION
It is an object of the invention to illuminate and image biological tissue, principally in vivo, and to convey the image in the form of light to an image receiver for conversion to electrical signals and for automatic recognition of biological features.
SUMMARY OF THE INVENTION
A light image is conveyed from a biological tissue through a flexible optical system to an image receiver, where it is converted to a form which may be entered into a computer. The computer segments the image by generating a segmentation mask defining the boundary of a region of interest in at least one spectral band, estimates at least one rotationally and translationally invariant statistical measure of coefficient distributions of the multiscale wavelet maxima representations of the digital images in at least one spectral band, characterizes the condition of the tissue based on the estimated values, and outputs the characterization of the condition of the tissue.
