Abstract
Embodiments described herein enhance the visualization of certain conditions contained in a video depicting motion in a field of view, in which the enhancements include but are not limited to one or more of: adjusting the appearance of video when objects are at different distances from a video acquisition device; aligning phase of motion obtained from different video acquisition devices; accentuating frequency phenomena that may be masked or obstructed in the presence of other frequencies of motion; differentiating motion data to obtain velocity or acceleration waveforms or spectra; applying a color scheme to pixels in a scene to highlight motion with specific characteristics or to amplify motion or provide indication of absolute motion; and determining spatial or temporal regions in the video to amplify based on the predetermined parameters.
