Drawbacks of curve-based shape representations

• Curves do not represent the interior of shapes, can lead to un-intuitive matches

• Curve-based representation are sensitive to spatial arrangement of parts

• Curve matching can fail in presence of occlusion that modifies the spatial arrangement of parts

• Database indexing results

• Ten nearest neighbors in percentages

• Curve Matching (100, 98, 98, 99, 95, 95, 91, 85, 75, 51)

• Shock Matching (100, 100, 100, 99, 99, 99, 97, 96, 95, 87)
