Posture Matching Results for Nine Curves

The horizontal axis represents the checking frames, which were taken once every 20 frames. The vertical axis represents the frames of relative postures that were best matching with the postures at checking frames. Two red points and two yellow points indicate the matching results of the four fixed points in the virtual 3D. The two colors signify that these points were constrained to be at the same height. Naturally many subsets of blue points may have the same height, but this property was not checked. The net result is that almost every relative posture at each frame for each curve is unique. Given at least 50 samples per path and 9 paths, a total of more than 22,000 comparisons were made. This calculation makes the result that almost all of the 450 perfect matches are seen, even given that in many of the match pairings the tracing finger is at the same vertical height, remarkable.
