A new algorithm for the interrogation of 3D holographic PTV data based on deterministic annealing and expectation minimization optimization

A new algorithm for the interrogation of 3D holographic PTV data based on deterministic annealing... Recently we have presented a new particle tracking algorithm for the interrogation of 2D-PTV data [Kuzmanowski et al. (1998); Stellmacher and Obermayer (2000) Exp Fluids 28: 506 –518], which estimates particle correspondences and local flow-field parameters simultaneously. The new method is based on an algorithm recently proposed by Gold et al. [Pattern Recognition (1998) 31:1019–1031], and has two advantages: (1) It allows not only local velocity but also other local components of the flow field such as rotation and shear to be determine; and (2) it allows flow-field parameters also to be reliably determined in regions of high velocity gradients (e.g., vortices or shear flow). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Experiments in Fluids Springer Journals

Abstract

Recently we have presented a new particle tracking algorithm for the interrogation of 2D-PTV data [Kuzmanowski et al. (1998); Stellmacher and Obermayer (2000) Exp Fluids 28: 506 –518], which estimates particle correspondences and local flow-field parameters simultaneously. The new method is based on an algorithm recently proposed by Gold et al. [Pattern Recognition (1998) 31:1019–1031], and has two advantages: (1) It allows not only local velocity but also other local components of the flow field such as rotation and shear to be determine; and (2) it allows flow-field parameters also to be reliably determined in regions of high velocity gradients (e.g., vortices or shear flow).
