Abstract

The authors performed several experiments where they made sure that the only cues available to the observer were contour and motion. It turns out that when humans combine information from contour and motion to reconstruct the shape of an object in view, if the results of the two modules-shape from contour and structure from motion-are inconsistent, they totally discard one of the cues and an illusion is experienced. The authors describe examples of such illusions and identify the conditions under which they happen. Finally, they introduce a computational theory for combining contour and motion using the theory of regularization. The theory explains such illusions and predicts many more.<>

运动边界幻象及其正则化
作者做了几个实验,确保观察者能得到的唯一线索是轮廓和运动。事实证明,当人类将来自轮廓和运动的信息结合起来重建所见物体的形状时,如果这两个模块——来自轮廓的形状和来自运动的结构——的结果不一致,他们就会完全放弃其中一个线索,从而产生错觉。作者描述了这种错觉的例子,并确定了它们发生的条件。最后,介绍了一种利用正则化理论将轮廓和运动结合起来的计算理论。该理论解释了这些幻觉,并预测了更多的幻觉。
