移位帧累积技术在抑制图像噪声的同时,避免了运动图像直接帧累积所带来的边缘模糊,从而有效地提高了运动图像的像质。准确判定目标在图像中的运动方向及移位量是移位帧累积技术的关键。提出了一种适用于运动图像序列的目标移位参数快速检测方法。该方法通过相应算法产生包含特征像素的帧差图像,并通过对特征像素的统计进行目标运动方向的判别及移位量的计算,从而实现对目标运动参数的自动检测。实验结果表明移位量的检测值与实际值具有良好的一致性。
The shift frame accumulation technique can suppress the image noise and avoid the edge blur caused by the accumulation of the direct frame of the moving image, thereby effectively improving the image quality of the moving image. Accurately determine the target in the image of the direction of motion and shift is the key shift frame accumulation technology. A fast detection method of target shift parameters for moving image sequences is proposed. The method generates the frame difference image containing the feature pixels through the corresponding algorithm, and through the statistics of the feature pixels, the direction of the target is determined and the displacement is calculated, so that the target motion parameters can be automatically detected. The experimental results show that the detection value of displacement is in good agreement with the actual value.
