US 9,805,475 B2 · Eulerian motion modulation

Abstract

In one embodiment, a method of amplifying temporal variation in at least two images includes converting two or more images to a transform representation. The method further includes, for each spatial position within the two or more images, examining a plurality of coefficient values. The method additionally includes calculating a first vector based on the plurality of coefficient values. The first vector can represent change from a first image to a second image of the at least two images describing deformation. The method also includes modifying the first vector to create a second vector. The method further includes calculating a second plurality of coefficients based on the second vector.

Dependent claims

A method of amplifying temporal variation in at least two images, the method comprising:

for each particular pixel of the at least two images, detecting a temporal variation of the particular pixel of the at least two images by applying a bandpass filter configured to analyze frequencies over time, the resulting detected temporal variation of the particular pixel between the two images being below a particular threshold;
and
amplifying the detected temporal variation of each particular pixel;
and
providing at least two modulated images by adding the amplified temporal variation to the at least two images by synthesizing the modulated images, for an amplification factor α, according to ƒ(x+(1+α)δ(t)), δ(t) being a displacement function.
