In chapter two, the required background about wavelet theory and perceptual coding techniques is briefly introduced. In this section, we explain why we choose the technology based on discrete wavelet transformation rather than other transformation methods to embed watermarking.
第二章首先简要介绍了小波分析的理论背景和感知编码技术，说明了在小波变换域嵌入水印的优势，随后阐述了在水印技术中常用的HVS模型。
