A Reversible Data Hiding Scheme Based on Neighboring DCT Coefficient Difference
碩士 === 國立屏東教育大學 === 資訊科學系碩士班 === 102 === In this thesis, we propose a method based on the histogram of differences between each coefficient of discrete cosine transformation and its corresponding coefficient in its neighboring blocks.First, we use the integer DCT coefficients to convert the pixel v...
