...Tianshu Liu; David M. Salazar; Hassan Fagehi; Hassan Ghazwani; Javier Montefort; Parviz Merati A hybrid method for particle image velocimetry (PIV) is developed to overcome the limitations of the optical flow method applied to PIV images with large displacements. The main elements of the hybrid...
