Reference frames in early motion detection.
To perceive the real motion of objects in the world while moving the eyes, retinal motion signals must be compensated by information about eye movements. Here we study when this compensation takes place in the course of visual processing, and whether uncompensated motion signals are ever available. We used a paradigm based on asymmetry in motion detection: Fast-moving objects are found easier a...
متن کاملApparent motion and reference frames
This article presents a selective overview of motion perception starting with its early philosophical underpinnings. Its role in Gestalt psychology is highlighted including the discovery of the relativity of motion perception and form-motion interactions. The use of reference frames in the computation of motion is illustrated with examples, leading to its current implications on non-retinotopic...
متن کاملAdjacent visual representations of self-motion in different reference frames.
Recent investigations indicate that retinal motion is not directly available for perception when moving around [Souman JL, et al. (2010) J Vis 10:14], possibly pointing to suppression of retinal speed sensitivity in motion areas. Here, we investigated the distribution of retinocentric and head-centric representations of self-rotation in human lower-tier visual motion areas. Functional MRI respo...
متن کاملOn Spatial Reference Frames in Qualitative Motion Representation
In the discussion of spatial representations in technical as well as in biological systems, frames of reference are of great importance. In this paper, we focus on spatial frames of reference in motion representation and stress that we have to introduce a distinction between frames of reference in measurement and in representation. We discuss some problems that arise in qualitative motion repre...
متن کاملQualitative Motion Representation in Egocentric and Allocentric Frames of Reference
In qualitative motion representation, frames of reference play an important role as well in measuring of the motion data as in representation and application of algorithms. This paper discusses motion representation in egocentric and allocentric frames of reference and begins with some general considerations on motion representation through qualitative distances and directions that apply to bot...
