Dynamical emergence of a neural solution for motion integration
FIGURE 1: (a) Measuring motion of an object from a localized receptive field RF may lead to ambiguous results (red arrow) compared to physical motion (blue arrow): it’s the aperture problem. (b) In natural scenes, we may constrain motion representation by using the prior knowledge that motion is roughly conserved along path-lines. We denote it as a “liquid-like” prior since it is equivalent to ...
متن کاملA neural model of luminance-gated recurrent motion diffusion for 2D motion integration and segmentation
We propose a model of motion integration modulated by luminance information, which is able to explain the percept on a large class of motion stimuli facing the aperture problem. This model is related to other multi-layer architectures incorporating both feedforward, feedback and inhibitive lateral connections and is inspired by the motion processing cortical areas in the primate (V1, V2, MT). O...
متن کاملA neural model for the integration of stereopsis and motion parallax in structure from motion
We introduce a model for the computation of structure-from-motion based on the physiology of visual cortical areas MT and MST. The model assumes that the perception of depth from motion is related to the firing of a subset of MT neurons tuned to both velocity and disparity. The model's MT neurons are connected to each other laterally to form modulatory receptive-field surrounds that are gated b...
متن کاملNeural models of motion integration and segmentation
A neural model is developed of how motion integration and segmentation processes compute global motion percepts. Figure-ground properties, such as occlusion, influence which motion signals determine the percept. For visible apertures, a line's extrinsic terminators do not specify true line motion. For invisible apertures, a line's intrinsic terminators create veridical feature tracking signals,...
متن کاملDynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
