Suppressing atmospheric turbulent motion in video through trajectory smoothing
چکیده انگلیسی

Dynamic geometric distortion has been observed in the video captured by optical sensors in the presence of atmospheric turbulence. The distortion is caused by gradients in refractive index in the atmosphere resulting from temperature gradients in the air. This problem has been addressed previously mainly through a reference video approach which cannot handle the cases where real motion exists. In this paper, we propose a new atmospheric turbulent motion suppression algorithm that is able to suppress the turbulent motion significantly while the natural motion of objects/camera such as panning/zooming in the video is preserved.
