摘要
分析了三帧差算法的传递函数,提出了带通滤波算法。该算法将数字带通滤波器应用于图像处理中,有效衰减通带外信号,改善三帧差算法对环境噪声敏感的问题。
Based on analysis of transfer function of three-fi＇ame difference algorithm, band-pass filtering algorithm is proposed. The algorithm was applied to image processing to attenuate outside pass band signals and solve the problem of three-frame difference algorithm is sensitive to sentimental noise.
