Abstract :
Many surfaces of objects are bounded by planar bilaterally symmetric figures. When these figures are imaged under orthographic projection a skewed symmetric contour results. In this paper a new, fast local method to recover skewed symmetries from curve segments is proposed. It can be applied to complete as well as to occluded contours. Furthermore, the skewed symmetry property is employed to overcome fragmentation of a contour during segmentation
