提出了一种被其他物体部分遮挡的偏对称物体的轮廓补全方法。该方法假设一个形状的偏对称性可以通过与其在非正交平面上的反射的相关性来测量。在假设条件下，该方法估计一个斜对称轴和一个斜横角，然后考虑斜横角将轮廓反射到估计的轴上。利用反射轮廓作为补片，恢复轮廓被遮挡的部分。然而，由于遮挡造成的信息丢失，反射轮廓从正确位置略微移动。该方法在小范围内移动反射轮廓，使其与原始轮廓平滑连接。通过与人类感知的对比，实验验证了该方法的有效性和局限性。
This paper proposes a method for contour completion of a skew-symmetry object which is partly occluded by other objects. The proposed method assumes that skew symmetry of a shape can be measured by correlation with its reflection on a no orthogonal plane. Under the assumption, the method estimates a skew-symmetry axis and a skew transverse angle, and then reflects the contour to the estimated axis considering the skew-transverse angle. Using the reflected contour as a patch, the occluded part of the contour is restored. However, due to the information loss caused by occlusion, the reflected contour slightly moves from the correct position. The method moves the reflected contour within a small range to smoothly connect it with the original contour. We experimentally confirmed the effectiveness and limitation of the proposed method by comparing the proposed method with the human perception.
