This report investigates the problem of matching two different sketches of the same scene. The process of matching enables pairing of corresponding parts of the two sketches thus allowing registration of one sketch with respect to the other. Once registered, detection of matching subpatterns andor discrepancies is possible. Sketches are represented as structured arrays of points Cartesian coordinates and other associated information which embody the most important features of the sketch. Two sketches are matched by comparing all point pairs of one sketch with those of the other. The decision as to whether or not one point pair fuzzily matches another is based on how well the length and slope of the imaginary line segment between the first pair coincides with the length and slope of the second pair.
