Optimal size for perceiving motion decreases with contrast
Visual patterns have widely varying contrasts and elicit local signals of varying reliability, ranging from noisy to relatively noise-free. One way to deal efficiently with the variable visual input is to employ flexible neural mechanisms that adapt to changing conditions. We investigated whether the spatial properties of motion mechanisms change with stimulus contrast and found that the optima...
متن کاملPerceiving self-motion in depth: the role of stereoscopic motion and changing-size cues.
During self-motions, different patterns of optic flow are presented to the left and right eyes. Previous research has, however, focused mainly on the self-motion information contained in a single pattern of optic flow. The present experiments investigated the role that binocular disparity plays in the visual perception of self-motion, showing that the addition of stereoscopic cues to optic flow...
متن کاملPerceiving a discontinuity in motion.
Studies have shown that the position of a target stimulus is misperceived owing to ongoing motion. Although static forces (fixation, landmarks) affect perceived position, motion remains the overwhelming force driving estimates of position. Motion endpoint estimates biased in the direction of motion are perceptual signatures of motion's dominant role in localization. We sought conditions in whic...
متن کاملOptimal quadtree for variable block size motion estimation
In this paper, we present a new approach to find the best quadtree for variable block size (VBS) motion estimation. In this approach, the quantizer which encodes the prediction residual is also jointly optimized in a rate-distortion sense. The desired balance of the bit allocation between the motion vector coding and the residual error coding is achieved by a Lagrange multiplier approach for th...
متن کاملActing while perceiving: assimilation precedes contrast
To explore the nature of specific interactions between concurrent perception and action, participants were asked to move one of their hands in a certain direction while simultaneously observing an independent stimulus motion of a (dis)similar direction. The kinematics of the hand trajectories revealed a form of contrast effect (CE) in that the produced directions were biased away from the perce...
