The face sequence. This sequence was recorded at 7.5 frames per second with a Point Grey Grasshopper. As in the books sequence, we use a variable exposure time. Click on the video to start playing.

• Flow result from frame 11 to 12
• Flow result from frame 13 to 14

Frame 11 to frame 12

In this example, the source (frame 12) is blurred, and the target (frame 11) is sharp.

Please move your mouse cursor over the small images to toggle between the results.

In its attempt warp the source to match the sharpness of the target, the baseline method produces inaccurate flow at the left hairline and the tip of the nose. Our method better preserves the appearance of the source.

Frame 13 to frame 14

In this example, the source (frame 14) is sharp, and the target (frame 13) is blurred.

The baseline method clearly distorts the eyes and mouth while also making the hairline and eyebrows appear blurred. Our method better preserves the sharpness of the source without distorting the eyes or the mouth.
