Dynamic Visual Motion Estimation
Visual motion is the projection of scene movements on a visual sensor. It is a rich source of information for the analysis of a visual scene. Especially for dynamic vision systems the estimation of visual motion is important because it allows to deduce the motion of objects as well as the self-motion of the system relative to the environment. Therefore, visual motion serves as a basic informati...
متن کاملEstimation of Visual Motion in Image Sequences
Preface This thesis has been prepared at the IMSOR group of the Institute of Mathematical Modelling (IMM), the Technical University of Denmark, in partial fulfillment of the requirements for the degree of Ph.D. in engineering. The thesis discuss different aspects of the problem of estimating the visual motion given a sequence of images. The treatment of the subject is not exhaustive, nor detail...
متن کاملNonlinear circuits for naturalistic visual motion estimation
Many animals use visual signals to estimate motion. Canonical models suppose that animals estimate motion by cross-correlating pairs of spatiotemporally separated visual signals, but recent experiments indicate that humans and flies perceive motion from higher-order correlations that signify motion in natural environments. Here we show how biologically plausible processing motifs in neural circ...
متن کاملVisual Motion Estimation for Tumbling Satellite Capture
Robotic service vehicles are presently seen as a viable means for performing satellite maintenance and ESA (European Space Agency) is presently investigating the possible characteristics and potential of a Geostationary Service Vehicle (GSV). A stereovision tracking system should be included in this GSV to help the operator track and capture the target satellite. This paper deals with a system,...
متن کاملDynamic Visual Motion Estimation from Subspace Constraints
The problem of estimating rigid motion from projections may be characterized using a nonlinear dynamical system, composed of the rigid motion constraint and the perspective map. The time derivative of the output of such a system, which is called the “motion field” and approximated by the “optical flow”, is bilinear in the motion parameters, and may be used to specify a subspace constraint on ei...
