Abstract :
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. The results of defect detection have good accuracy as compared to two well-known approaches. Application of our technique can be used in the recovery of damaged aged films.
