Abstract :
Line scratches are a common problem in archived motion pictures. They are caused by the abrasion of the film material as it passes through the projection mechanism. This paper presents a technique for detecting and removing these line artefacts. The method employs a model of the line profile for detection and the 2D Autoregressive model (2D AR) of the image for interpolation.
