| 摘 要： | 提出了一种新的基于Fourier-Mellin的电子稳像算法,用于消除由于推扫平台系统姿态不稳所造成的图像抖动。采用Fourier-Mellin算法和相位相关算法求取待稳定图像帧与参考图像帧之间的旋转角度和缩放及平移参数,并通过校正一组抖动的图像帧来验证所提出的算法。实验结果表明算法很好地估计并补偿了旋转和平移运动,能够满足一般要求。

| Abstract: | A novel method for electronic image stabilization based on Fourier-Mellin is proposed,which is used to remove video jitter caused by the jitter of push-broom flat.The rotation,scaling and translation parameters between the stabilized image and the reference image are acquired by Fourier-Mellin algorithm and phase correlation algorithm.The algorithm effect is testified by aligning a set of jitter images.Experimental results show that the proposed method can detect therotation and translation between images e... |
