Line scratch detection in films are challenging problem. In our approach proposed a spatial line scratch detection algorithm and temporal filtering step for detecting Line scratch in robust manner. This algorithms provides a precise description of the detected scratches. This process is more robustness and lack of external parameters is ensured by the combined use of a contrario methodology It performed significant advantages over previous work. Line scratches are common degradations in motion picture films. This paper presents an efficient method for line scratches detection. 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 digital restoration is a three-stage process. The first stage is a detection process, running without human interaction on the raw image sequence. Motion compensation is computed during this step, and relevant information stored. Line scratches are easily visible as vertical lines of bright or dark intensity, oriented more or less vertically over much of the image. Temporal anti-aliasing seeks to reduce or remove the effects of temporal aliasing. Temporal aliasing is caused by the sampling rate (i.e. number of frames per second) of a scene being too low compared to the transformation speed of objects inside of the scene; this causes objects to appear to jump or appear at a location instead of giving the impression of smoothly moving towards them. To avoid aliasing artifacts altogether, the sampling rate of a scene must be at least twice as high as the fastest moving object.
