As featured in the Journal of Hydraulic Research Paper "Implications of the selection of a particular modal decomposition technique for the analysis of shallow flows". This algorithm connects the spatially orthogonal Proper Orthogonal Decomposition with the temporally orthogonal Dynamic Mode Decomposition. From flow visualisation images, PIV or CFD vector fields it is possible to extract coherent structures which are quasi-spatially and temporally orthogonal.
Two example cases are included with the script. Please cite:
