Robust 4D Flow Denoising Using Divergence-Free Wavelet Transform
PURPOSE: To investigate four-dimensional flow denoising using the divergence-free wavelet (DFW) transform and compare its performance with existing techniques. THEORY AND METHODS: DFW is a vector-wavelet that provides a sparse representation of flow in a generally divergence-free field and can be us...
