Reliable Estimation of Dense Optical Flow Fields with Large Displacements
In this paper we show that a classic optical ow technique by Nagel and Enkelmann (1986) can be regarded as an early anisotropic di usion method with a di usion tensor. We introduc...

Flow-Based Local Optimization for Image-to-Geometry Projection
—The projection of a photographic dataset on a 3D model is a robust and widely applicable way to acquire appearance information of an object. The first step of this procedure is...

Estimating Translation/Deformation Motion through Phase Correlation
Abstract. Phase correlation techniques have been used in image registration to estimate image displacements. These techniques have been also used to estimate optical ow by applying...

Audio-visual flow -a variational approach to multi-modal flow estimation
Just as a motion field is associated to a moving object, an audio field can be associated to an object that can behave as a sound source. The flow field of such a sound source whi...

Multiresolution moment filters
We define multi-scale moments that are estimated locally by analyzing the image through a sliding window at multiple scales. When the analysis window satisfies a two-scale relatio...
