Removal of Scratches in Videos by Adaptive Filtering Technique Using MATLAB

In this paper a fast algorithm for removing line scratches in movies is presented. It is strongly based on exploiting the defect visibility in the image. To aim this, the Weber's law can be applied to coefficients of an over-complete wavelet representation of the degraded image. The intensity of the defect, which is represented as a light diffraction effect, is then attenuated in the vertical and approximation sub-bands till the minimum threshold of visibility is reached. The experimental results are very satisfying: the image is completely recovered without local artifacts or annoying smoothing effects. This paper discuss about frame conversions from a digital video of specific length and then preprocess the Image in order to enhance the Image quality and then performing the process of line scratch removal or artifacts. The final video is once again framed from the processed frames .the overall system is developed in Matlab through the guide model and the results are analyzed.
