Hybrid Data Hiding Scheme Based on Least Significant Bit and Pixel Value Differencing
碩士 === 朝陽科技大學 === 資訊管理系 === 104 === This paper presents a data-hiding method based on least-significant-bit (LSB) substitution and an improved Pixel-Value Differencing (PVD) method for grayscale images. The proposed method partitions the cover image into 5×5 non-overlapping blocks. For each block, s...
