Magic Square Algorithm for Optimization of Pixel Pair Modification Data Hiding
碩士 === 臺中技術學院 === 資訊工程系碩士班 === 99 === The magic squares based on pixel pair modification (PPM) for data hiding has the drawbacks of payload on PSNR’s of LSB. The traditional PPM-related methods do not consider the combination of square contents. In this thesis, a heuristic magic square algorithm f...
