License plate from blurred photo taken with a 'Flutter Shutter Camera'

This example shows a potential application of our camera that flutteres the shutter open and closed in a carefully chosen binary sequence. The binary sequence has a broadband frequency response (similar to binary sequences used in astronomy and audio analysis). The fluttering preserves high spatial frequencies, improving invertibility and hence the corresponding deblurring becomes a well-posed problem.
