Sensory Integration: Neuronal Adaptations for Robust Visual Self-Motion Estimation
Recent studies on the fly visual system have revealed how the morphology of visual interneurons and their lateral electrical connectivity helps overcome a notorious problem in visuomotor control - the ambiguity of local sensor signals.
متن کاملVisual Vestibular Interactions for Self Motion Estimation
Accurate perception of self-motion through cluttered environments involves a coordinated set of sensorimotor processes that encode and compare information from visual, vestibular, proprioceptive, motor-corollary, and cognitive inputs. Our goal was to investigate the visual and vestibular cues to the direction of linear self-motion (heading direction). In the vestibular experiment, blindfolded p...
متن کاملSensory cancellation of self-movement facilitates visual motion detection.
The nervous system continuously predicts the sensory consequences of self-generated actions. These predictions can be used to cancel self-generated sensory information. It has been hypothesized that this cancellation process may serve to increase the perceptual sensitivity to unpredicted external events. Here, we provide the first empirical evidence for this idea. Participants were required to ...
متن کاملRobust Techniques for Visual Motion
In a vision guided robotic manipulator it is necessary to estimate the motion parameters of the moving object before some control scheme can be implemented. The classical solution to the general problem of state estimation from a sequence of noisy measurements is the Kalman lter which aims at minimizing the covariance of the estimation error. In this paper certain concepts from robust control s...
متن کاملRobust Estimation for Motion Parameters
The performance of least squares method ca'n be improved by changing the error metric so that points which lie far from the bulk of data do not influence the final value—that is to reject the outliers. In this paper, the combination of two robust estimators are used to obtain motion parameters of a camera from matched image features. Results obtained show that the robust estimator has the abili...
