¿µ¹®³»¿ë¿ä¾à The importance of DRM technologies, especially the watermarking technology, is getting larger and larger as the demand for the digital contents is increased. But the standard for the evaluation of watermark technology is not set up properly due to the conflicts between interested parties and technical difficulties. When evaluating the performance of PAT, the result could be varying by the image used and evaluation criteria employed. Therefore to evaluate the performance of watermarking technologies objectively, standardizing of test images are essential. This standard provides the quantitative evaluation guidelines for the selection of standard test images which could be used to evaluate the performance of watermarking technologies objectively.
