Examples
- We propose several watermarking techniques after analyzing other watermarking methods detailedly . the main contributions can be summarized as following : ( 1 ) based on previous work , we proposed an improved spatial self - embedding watermarking technique . we save the quantized dct coefficients using group encoding while not using bit matrix which restricts saving bit length of each dct coefficient
本文的创新之处总结如下： ( 1 )提出了一种改进的具有修复功能的空域自嵌入水印算法，利用分组编码保存量化后的dct系数，改善了修复效果，克服了以往使用位图矩阵的不足，具有通用性与实用性。
