Abstract

Stabilization of atmospheric turbulence-distorted video not only needs to remove turbulence-induced spatiotemporal distortions but also needs to improve the sharpness. Using complex steerable pyramid (CSP), we propose a method to stabilize the turbulence-distorted video. First, each frame is decomposed into multiscale and multidirectional phases and amplitudes using CSP. Second, a lowpass filter is used to suppress the local phase variations to stabilize the spatiotemporal distorted. Next, we improve the sharpness by selecting and fusing the optimal amplitude. Experimental results demonstrate the proposed method can stabilize the video and improve the sharpness simultaneously.
