Image Processing Methods Performance for Digital Re-establishment of Older Paintings

Several methods have been proposed for detection and removals of cracks in digitized paintings. Cracks not only deteriorate the quality of painting but also question its authenticity. In this paper, cracks are identified by the top-hat transform methods to identify cracks. After detecting cracks, the breaks which are wrongly identified as cracks are separated using region growing. Canny edge detection is used for identify the edges in images. Finally, in order to restore the image bilateral filter are used. This methodology of detection and elimination of cracks in digitized paintings is shown to be very effective in preserving the edges also
