Some embodiments are directed to a method, corresponding system, and corresponding apparatus for rendering a video and/or image display to amplify small motions through video magnification. Some embodiments include a new compact image pyramid representation, the Riesz pyramid, that may be used for real-time, high-quality phase-based video magnification. Some embodiments are less overcomplete than even the smallest two orientation, octave-bandwidth complex steerable pyramid. Some embodiments are implemented using compact, efficient linear filters in the spatial domain. Some embodiments produce motion magnified videos that are of comparable quality to those using the complex steerable pyramid. In some embodiments, the Riesz pyramid is used with phase-based video magnification. The Riesz pyramid may phase-shift image features along their dominant orientation, rather than along every orientation like the complex steerable pyramid.
