Moment Invariants for the Analysis of 2D Flow Fields [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2007 We present a novel approach for analyzing two-dimensional (2D) flow field data based on the idea of invariant moments. Moment invariants have traditionally been used in computer vision applications, and we have adapted them for the purpose of interactive exploration of flow field data.

Dynamic Occlusion Analysis in Optical Flow Fields [PDF]
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1985 Optical flow can be used to locate dynamic occlusion boundaries in an image sequence. We derive an edge detection algorithm sensitive to changes in flow fields likely to be associated with occlusion. The algorithm is patterned after the Marr-Hildreth zero-crossing detectors currently used to locate boundaries in scalar fields.

Fractal modelling and analysis of flow-field images [PDF]
2010 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2010 We introduce stochastic models for flow fields with parameters that dictate the scale-dependent (self-similar) character of the field and control the balance between its rotational vs compressive behaviour. The development of our models is motivated by the availability of imaging modalities that measure flow vector fields (flow-sensitive MRI and ...
