The hydrological monitoring of flow data is important for flood prevention and modern river
management. However, traditional contact methods are increasingly struggling to meet the …

We survey the current state of the art in industrial gas sensing, explaining how existing
sensing techniques estimate gas concentration, column density, total volume, and leak rate …

A wavelet-based optical flow method for high-resolution velocimetry based on tracer particle
images is presented. The current optical flow estimation method (WOF-X) is designed for …

This manuscript details recent improvements in a wavelet-based optical flow velocimetry
(wOFV) method that represents a more physically sound implementation and results in …

We propose in this paper a new formulation of optical flow dedicated to 2D incompressible
turbulent flows. It consists in minimizing an objective function constituted by an observation …

The performance of a wavelet-based optical flow velocimetry (wOFV) algorithm in extracting
high accuracy and high-resolution velocity fields from tracer particle images in wall-bounded …

We present principled algorithms for measuring the velocity and 3D location of refractive
fluids, such as hot air or gas, from natural videos with textured backgrounds. Our main …

Efficient optical flow estimation with high accuracy is a challenging problem in computer
vision. In this paper, we present a simple but efficient segmentation-based PatchMatch …

This work is concerned with the ill-posed inverse problem of estimating turbulent flows from
the observation of an image sequence. From a Bayesian perspective, a divergence-free …

In this work, we present an efficient optic flow algorithm for the extraction of vertically
resolved 3D atmospheric motion vector (AMV) fields from incomplete hyperspectral image …
