Abstract: The conservation of Art especially the old paintings has been a matter of concern. Numerous methodologies using Digital Image Processing have been proposed regarding the fixation of the cracks. This has been done so as to provide clues to art historians, and the general public on how the painting would look like in its initial state, i.e., without the cracks. In this paper, a brief Literature Survey has been made so as to analyze different methodologies that have been used for the detection as well as for the crack filling. This article discusses a number of modern techniques used for the analysis of works of art.
