Claim Text:
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 band; downsampling at least one image of the first set one or more times; applying a Riesz transform to at least one of the downsampled images; generating an image representation, based upon the application of the Riesz transform, the image representation including a second set of images, at least one image of the second set being horizontally phase shifted with respect to a given corresponding image of the first set, the image representation including a third set of images, at least one image of the third set being vertically phase shifted with respect to a given corresponding image of the first set; computing a local phase for at least one image of the image representation; generating a temporally filtered local phase based upon applying one or more temporal band pass filters to the local phase and based upon one or more previous local phases; generating an updated image representation based upon the temporally filtered local phase and the at least one image of the image representation; amplifying one or more images of the updated image representation; constructing a given replacement image based upon the amplified image representation, the replacement image corresponding to the given frame and the replacement image exhibiting amplified motions as compared with the given frame; and displaying the given replacement image.
