Damage Detection in Bridge Structures through Compressed Sensing of Crowdsourced Smartphone Data

Figure 7

Comparison between the original signal (sampled at 40 Hz) and the reconstructed signal for different compression levels, recorded by a randomly selected vehicle while crossing the intact bridge (numerical). (a) Compression level = 20%. (b) Compression level = 50%. (c) Compression level = 80%.
