摘要

线条划痕是电影胶片中常见的劣化现象。本文提出了一种基于卡尔曼滤波的线路划痕检测方法。研究了一种新的插值技术，处理线伪影周围的低频和高频(即薄膜颗粒)，以实现损坏区域的近不可见重建。我们的线条划痕检测和去除技术已经在几个电影序列上得到了验证。

Detection and removal of line scratches in motion picture films

Line scratches are common degradations in motion picture films. This paper presents an efficient method for line scratches detection strengthened by a Kalman filter. A new interpolation technique, dealing with both low and high frequencies (i.e. film grain) around the line artifacts, is investigated to achieve a nearby invisible reconstruction of damaged areas. Our line scratches detection and removal techniques have been validated on several film sequences.
