Adaptative Multigrid and Variable Parameterization for Optical-flow Estimation
We investigate the use of adaptative multigrid minimization algorithms for the estimation of the apparent motion field. The proposed approach provides a coherent and... -
The Intrinsic Structure of the Optic Flow Field
n this paper, a generating equation for optic flow is proposed that generalises Horn and Schunck's Optic Flow Constraint Equation (OFCE). Whereas the OFCE has an... -

Wavelets and Fluid Motion Estimation
This work falls within the general problematic of designing measurement tools adapted to the specificities of fluid flows. The development of digital imaging, combined... -
Perception of shapes from motion<br />Bayesian combination of optic flow and ...
Perception can be seen as collecting and confronting various pieces of information in order to understand the environment. One uses many semsory modalities each one... -

EGOCENTRIC INFLUENCE ON GEOCENTRIC SPATIAL PERCEPTION - ESTIMATING THE POSSIB...
Perceiving space is a relevant task in determining our relationships with the environment. In behavioral neuroscience, investigating this spatial relationship can... -
Effective Wavelet-Based Regularization of Divergence-free Fractional Brownian...
This paper presents a method for regularization of inverse problems. The vectorial bi-dimensional unknown is assumed to be the realization of an isotropic...
