摘要
生物视觉关于二阶运动的研究成果,为计算机视觉的发展提供新的理论支持和研究方向.本文深入分析二阶运动信号,按照信号调制的方式将其分为空间调制、时间调制、时空调制三类运动.利用基于相关模型的一阶运动感知系统及纹理捕获器加相关模型的二阶运动感知系统对各类二阶运动现象进行实验,计算结果支持生物视觉关于二阶运动是由非线性的感知系统加工的结论.
The study of the second order motion in biological vision is a new source of inspiration for algorithms and research directions in computer vision. In this paper, the second order motion can be divided into three typical group according to the modulation types： spatial modulate motion, temporal modulate motion and spatio-temporal modulate motion. Experiments are conducted on the first order motion perception based on correlation model and the second order motion perception by correlation model preceded with a nonlinear process called texture grabber. The computational results are consistent with the previous suggestion that the second order motions are processed by nonlinear system.
