Figure 2.

Comparison of (a) original and (b) motion magnified results showing pneumatic-induced motion of an eardrum with a sealed ear canal. The spatiotemporal slices for the blue, green, red, and yellow lines are shown in (a-1 through a-4 and b-1 through b-4, respectively). Note that around 8 peaks of the cyclical motion are visible from the spatiotemporal slice. (c) Comparison of motions at the blue line of interest between original and motion magnified results. (d) Spatial and temporal variations of eardrum mobility can be examined after the motion is amplified. This dataset was acquired from a healthy adult volunteer, subject 1. The original and the motion magnified video results can be found in Video 1.
