Abstract: Jitter is a crucial error source that undermines the geometric and radiometric performance of satellite imagery.In order to enhance the feasibility and trust of retrieving jitter from imagery,this paper proposes an intelligent jitter detection method using parallax observation based on phase correlation with local frequency analysis.Through connecting structural image representation with phase correlation,the local and global phase information is fully utilized to reduce the influence of radiometric variation,noise and other interferences on subpixel translation estimation.The subpixel phase correlation is integrated into the framework of jitter detection using parallax observation,which ensures the accurate and robust dense matching and achieves effective jitter detection.The effectiveness of the proposed method is demonstrated by method comparison using images with realistic radiometric difference as well as jitter detection test using ZY-3 images.The promising results indicate that,the subpixel phase correlation method with local frequency analysis outperforms other state-of-the-art methods in the presence of radiometric difference and noise,achieving a matching accuracy of 0.05 pixels,and the proposed jitter detection method effectively estimates the jitter information of ZY-3 satellite.
