In this study, we developed a novel optical-flow algorithm for determining the wall shear-
stress on the surface of objects. The algorithm solves the thin-oil-film equation using a …

The performance of wavelet-based optical flow velocimetry (wOFV) applied to tracer particle
images from hypersonic boundary layer flows is assessed. Two modifications of wOFV to …
