提出了一种新的基于空间特征的划痕检测和去除算法。该算法将对划痕的检测转化为对图像垂直投影序列的处理，降低了计算复杂度。实验结果表明，该算法能够有效地进行噪声干扰下划痕的检测和去除。

A new method for scratch removal based on spatial features is proposed. The method meets with good results with lower complexity because it performs on the projective array of the degraded image in the vertical direction. The method proves capable of removing scratches in heavily-degraded film sequences.
