What is it about?
This paper combines image processing techniques and turbulence theory to extract the signature turbulence from a recorded video and evaluate the level of turbulence with the accuracy that is comparable to a commercial scintillometer. Furthermore, the method can be used to extract the relative depths of objects in the scene, given that the ground condition is similar. A few examples of ranging static and moving objects are demonstrated through this paper.

Why is it important?
Turbulence distortion in imaging is usually regarded as obstacles for analysis. We propose new thinking in the opposite way where turbulence information can be actually used to produce useful information about the scene.
Perspectives
This is the first paper that actively use turbulence distortions in an image sequence to extract useful information in the scene. The method further empowers surveillance systems with the new information it provides.
