A model is presented, consonant with current views regarding the neurophysiology and psychophysics of motion perception, that combines the outputs of a set of spatiotemporal motion-energy filters to extract optical flow. The output velocity is encoded as the peak in a distribution of velocity-tuned units that behave much like cells of the middle temporal area of the primate brain. The model appears to deal with the aperture problem as well as the human visual system since it extracts the correct velocity for patterns that have large differences in contrast at different spatial orientations, and it simulates psychophysical data on the coherence of sine-grating plaid patterns.
本文提出了一个模型，该模型与当前关于运动感知的神经生理学和心理物理学的观点一致，它将一组时空运动能量滤波器的输出进行整合以提取光流。输出速度被编码为速度调谐单元分布中的峰值，这些单元的行为与灵长类动物大脑颞中区的细胞非常相似。该模型似乎能够像人类视觉系统一样处理孔径问题，因为它能为在不同空间方向上对比度有很大差异的图案提取正确的速度，并且它还能模拟关于正弦光栅格子图案连贯性的心理物理学数据。
