We test a biologically motivated filtering method [9] for noise decreasing in optical flow fields. We use the task of heading detection from optic flow as a way to estimate improvements of flow fields generated by a standard algorithm. The image sequences which we use for the testing are directly calculated from three dimensional real world data assuming a given self motion. Thus we retain the ...

We recorded neuronal activity in monkey medial superior temporal (MST) cortex during movement on a motorized sled. Most neurons showed a preferred heading direction, but some responded only when that heading was part of a particular path. Others responded only when the animal was at a certain place in the room, regardless of its path to that place. Video simulations of the self-movement scene e...

A computational architecture for direct estimation of heading direction from optic flow is proposed. By representing optic flow information as undulatory spatiotemporal patterns, global first-order differential analysis of the optic flow is reconducted to spatiotemporal filtering operations with local kernels characterized with respect to the fixation point (gaze). These operations can be mappe...

A Generalized Predictive Controller (GPC) for ship track keeping is introduced in this paper. A predictive model for desired heading angles is deduced, the controller is designed based not only on the prediction of the outputs (heading angles), but also on the prediction of the desired heading angles. A recursive algorithm for matrix inversion in the controller is also presented. Applied to car...

This study intended to determine if an acute bout of soccer heading alters postural control and pronounced self-reported symptoms of cerebral concussion. Collegiate soccer players were randomly assigned to one of 2 groups. Each participant completed a baseline postural control assessment prior to heading. Participants either simulated (control group; CG) or performed (experimental group; EG) 10...

This paper describes the development of a position and heading measurement system using for moving robots ( we call "LASER NAVIGATOR " ) which is composed of a scanning laser unit (SLU) mounted on a robot and three or more corner-cubes ( retro-reflectors ) fixed on the ground . A coordinate system and corner-cubes are arbitrarily set on a horizontal plane , and their coordinates have already me...

Many neurons in the dorsal medial superior temporal (MSTd) and ventral intraparietal (VIP) areas of the macaque brain are multisensory, responding to both optic flow and vestibular cues to self-motion. The heading tuning of visual and vestibular responses can be either congruent or opposite, but only congruent cells have been implicated in cue integration for heading perception. Because of the ...
