Method and apparatus for analyzing images
First Claim
1. A method of calculating a thermal path in a living body, comprising:
- operating a thermospatial imaging system for imaging the body and generating and storing in a memory a synthesized thermospatial image defined over a three-dimensional spatial representation of the living body and having thermal data associated with a surface of said three-dimensional spatial representation;
retrieving said thermospatial image from said memory;
identifying by an image processor, at least one thermally distinguishable spot in said thermospatial image and storing the at least one thermally distinguishable spot in a memory; and
by said image processor, using said thermospatial image and said thermally distinguishable spot for calculating the thermal path and generating an output indicative of the thermal path, wherein said thermal path is calculated by calculating a spatial gradient of said surface at said spot.

Abstract
A method of determining an internal three-dimensional thermally distinguishable region in the living body is disclosed. The method comprises obtaining a synthesized thermospatial image defined over a three-dimensional spatial representation of the living body and having thermal data arranged gridwise over a surface of the three-dimensional spatial representation in a plurality of picture-elements each represented by a intensity value over the grid. The method further comprises searching over the grid for at least one set of picture-elements represented by generally similar intensity values. For at least a few sets of picture-elements, the method defines a plurality of loci, each locus being associated with at least a pair of picture-elements of the set and defined such that each point of the locus is at equal thermal distances from individual picture-elements of the pair. The plurality of loci is used for determining the internal three-dimensional thermally distinguishable region.
