Evaluation of a wavelet-based optical flow algorithm through the use of large eddy simulations
Résumé
Recent progress in observations of wind fields by scanning aerosol lidar and motion estimation algorithms elevates interest in accuracy, precision , and resolution. Toward this, we are using large eddy simulations to advect a passive tracer in the model domain to mimic atmospheric aerosol. A wavelet-based optical flow algorithm is applied to the model output in order to derive dense motion vector fields. Each motion vector is compared with the known wind velocity at the corresponding point.
