Figure 5.10: False negatives for DTW-3D technique. Similar to the quaternion-based method, Dynamic Time Warping using 3D coordinate points based technique performs better than PCA-based and feature- based techniques. The false negatives are less in all the five queries compared to the quaternion-based method because the latter is very sensitive is very sensitive to small differences in joint configurations (see Fig 5.10). The pick up the box query gives 0% false negatives beacuse all the pick data files have the same orientation and 3-D location. Also the number of false positives are less which is an indication of a good technique (see Fig 5.11). 5.2.1 Overall Results The false positives detected by each method are shown in Figure 5.12 and the graph in Figure 5.13 shows the overall false negatives of each of the methods. 58
