摘　　要：基于对象的视频图像编码或视频监控系统中,在对采集的视频图像背景进行处理时,由于光线变化和摄像机本身造成的条状噪声因其特性与前景对象类似,是较难去除的噪声。采用曲线拟合的方法,对序列图像中各像素在时间方向的特征进行了分析,通过计算噪声在前N帧图像的变化规律,在后续帧中去除了条状噪声。该实验结果为视频对象分割和MPEG-4中sprite背景编码方法的实现奠定了基础。The stripe noise that arises from light changes and electromechanical interference during image acquisition in video is difficult to removal, especially in object-based video coding and surveillance system. A method of curve fitting of pixels in sequences images is presented in this paper. Based on the curve fitting parameters and its variety roles, the stripe noises are removed in the future frames. This method is important to realize the arithmetic of video object segment and sprite coding in MPEG-4.
