采用时间空间相关变分方法分析鲁棒光学流场

We present in this paper a novel collaborative scheme
dedicated to the measurement of velocity in fluid experimental
flows through image sequences. The proposed technique
combine the robustness of correlation techniques with
the high density of global variational methods. It can be considered
either as a reenforcement of fluid dedicated opticalflow
methods towards robustness, or as an enhancement of
correlation approachs towards dense information. This results
in a technique that is robust under noise and outliers,
while providing a dense motion field. The method was applied
on synthetic images and on real experiments in turbulent
flows carried out to allow a thorough comparison with a
state of the art optical-flow and PIV methods. 德国LaVision PIV/PLIF粒子成像测速场仪 Imager pro X PIV相机 用于粒子成像测速(PIV)的荧光示踪粒子
