Abstract
The present disclosure provides a method of correcting for a turbulence effect in a video comprising a plurality of frames. The method comprises determining a first background region and a region corresponding to a moving object in a first frame of the plurality of frames using a predetermined background model. A second background region in a second frame of the plurality of frames is then determined using the predetermined background model. A turbulence-corrected background region from the first background region and the second background region is generated and the region corresponding to the moving object and the turbulence-corrected background region is fused to form a turbulence-corrected frame. The method then updates the predetermined background model based on the turbulence-corrected frame and corrects for the turbulence effect in the second frame using the updated predetermined background model.
