Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method of rendering a video display, comprising the computer-implemented steps, by a processor and associated memory: receiving a video stream formed of a sequence of one or more frames, each frame having image content; for each given frame of the sequence of frames: generating a first set of images, each image of the first set corresponding to the given frame, and each image of the first set including a unique spatial frequency ba…
