摘要
为了提高船舶运动成像的电子稳像能力,进行运动图像位移补偿处理,提出基于相邻帧多尺度补偿的船舶运动图像快速位移补偿方法,对采集的原始船舶运动图像采用小波降噪方法进行图像降噪处理,对降噪的船舶运动图像进行多尺度的经验模态分解,结合运动图像相邻帧的像素特征进行电子稳像补偿,根据电子稳像输出结果进行图像位移的快速补偿,提高船舶运动图像的成像质量。仿真结果表明,采用该方法进行船舶运动图像位移补偿,对运动帧的连续成像效果较好,输出图像的峰值信噪比较高,表明对船舶运动图像的成像质量较高,能克服快速位移对运动图像成像质量的影响。
In order to improve the electronic image stabilization ability of ship motion imaging,motion image displacement compensation processing,a method of fast displacement compensation for ship motion images is proposed based on multi scale compensation of adjacent frames,wavelet denoising method of the original ship motion image acquisition using in image denoising,image denoising of the empirical mode of ship motion multi scale decomposition,combined with the characteristics of motion pixel images of adjacent frames of video stabilization compensation,according to the electronic image stabilization fast compensation output displacement image,improve the image quality of ship motion image.The simulation results show that using the method of ship motion image displacement compensation,better imaging effect of continuous motion frame,output the image of the high peak signal to noise ratio,shows that the ship motion image quality is higher,it can overcome the rapid displacement of motion image into like the effect of quality.
