一个便于识别的视觉运动表示应该突出简单运动之间的质的差异。我们认为,在这样的运动表示的第一阶段是明确的边界,我们定义为开始,停止,和力的不连续性。当这些边界中的一个发生运动时,人类观察者会有一种主观的印象,即发生了一些短暂的重大事件。我们进一步假设,当且仅当我们定义的边界之一出现时,才能看到主观运动边界之一。我们列举了所有可能的运动边界,并提供证据证明它们在心理上是真实的。
A representation of visual motion convenient for recognition should make prominent the qualitative differences among simple motions. We argue that the first stage in such a motion representation is to make explicit boundaries that we define as starts, stops, and force discontinuities. When one of these boundaries occurs in motion, human observers have the subjective impression that some fleeting, significant event has occurred. We go farther and hypothesize that one of the subjective motion boundaries is seen if and only if one of our defined boundaries occurs. We enumerate all possible motion boundaries and provide evidence that they are psychologically real.
