Volumetric Motion Magnification: Subtle Motion Extraction from 4D Data

The extension of Phase-based Video Motion Magnification into three-dimensions is presented in this work. technique uses a 3D complex steerable pyramid to decompose volumetric frames 4D dataset. resulting decomposition can be processed filter, amplify, or attenuate subtle motions occurring locally within the data, before inversion transform performed recreate images. Recent research has used Phase Based extract motion from 2D slices internal deformation data. This work demonstrates how extended on full images motions. Volumetric demonstrated qualitatively, amplify and indiscernible cylinder for visual identification. Then, ability enhance noise floor Digital Volume Correlation by more than factor 10 demonstrated.
