    Abstract: 在老舊影片之中,存在著不同類型的雜訊,例如汙點雜訊、直線雜訊等,而且在不同的雜訊上會擁有各別的特徵,因此針對各種存在於老舊影片中之雜訊,要以單一種方法達來到精確的雜訊偵測是很困難的。
    Aged motion pictures may contain different types of defects, such as spikes and scratch lines. Each type of defect has its different properties. It is relatively hard to precisely detect these defects on aged films by using only a single solution. This paper proposes two techniques to detect spikes and scratch lines on aged films. In detecting spikes, we use the motion estimation and morphological image processing. In detecting scratch lines, we propose to compute the mean of intensity on each column, and then use the standard deviation and compute the number of the weight to obtain the result of detecting.
