Abstract: In an embodiment, a method converts two images to a transform representation in a transform domain. For each spatial position, the method examines coefficients representing a neighborhood of the spatial position that is spatially the same across each of the two images. The method calculates a first vector in the transform domain based on first coefficients representing the spatial position, the first vector representing change from a first to second image of the two images describing deformation. The method modifies the first vector to create a second vector in the transform domain representing amplified movement at the spatial position between the first and second images. The method calculates second coefficients based on the second vector of the transform domain. From the second coefficients, the method generates an output image showing motion amplified according to the second vector for each spatial position between the first and second images.

Abstract: Techniques are disclosed to process certain information contained in a digital video signal. In particular, a time-varying signal present in the digit video signal may be supplanted with a replacement time-varying signal, negated, or obfuscated with a noise signal. Negation of the time-varying signal may include extracting said time-varying signal from the digital video signal, inverting the time-varying signal, and adding the inverted time-varying signal to the original digital video signal. Obfuscation of the time-varying signal may be accomplished by introducing a suitable noise signal to the original digital video signal. Supplanting the time-varying signal with a replacement signal may include negating the time-varying signal and introducing a desired replacement signal to the digital video signal.
