ABSTRACT
Previous research has provided evidence for the existence of two processing pathways, one for the perception of object motion (based on the detection of counterchange) and the other for the perception of objectless motion (based on the detection of motion energy). Counterchange mechanisms flexibly respond to oppositely signed changes in any feature at two locations. Motion energy mechanisms are dedicated to the detection of spatiotemporal changes in luminance. Demos are provided to illustrate both kinds of motion.

Perception of Two-Stroke Apparent Motion and Real Motion
Neural Information ProcessingAbstractMotion perception is an important visual ability of human beings. We can perceive motions not only from real motion but also from apparent motion. Usually, the direction of a perceived apparent motion reflects the real spatial shift between the ...
Modeling motion visual perception for video quality assessment
MM '11: Proceedings of the 19th ACM international conference on MultimediaContrast sensitivity of Human Visual System (HVS) plays an important role in perceiving visual stimuli, and consequently, it has a significant impact on the perceived video quality. This paper proposes a visual perception model based on foveated vision ...
Independent 3D Motion Detection Based on Depth Elimination in Normal Flow Fields
CVPR '97: Proceedings of the 1997 Conference on Computer Vision and Pattern Recognition (CVPR '97)This paper considers a specific problem of visual perception of motion, namely the problem of visual detection of independent 3D motion. Most of the existing techniques for solving this problem rely on restrictive assumptions about the environment, the ...
