Abstract: A color image of relatively large size is inserted in audio signal data as a watermark. And yet the watermark embedded audio signal data can be played back with sound quality very close to that of original audio signal data. The original audio signal data are reshaped into a matrix form to correspond to that of a color image file before wavelet transformed while the color image file undergoes a format conversion before discrete cosine transformed. The coefficients of the transformed audio signal data and the reformatted color image are combined before inverse-matrix-reshaped and subsequently inverse-wavelet-transformed to finally generate an audio signal wherein a color-image watermark has been inserted.
Abstract translation: 音频信号数据中插入比较大的彩色图像作为水印。 然而，水印嵌入音频信号数据可以以非常接近原始音频信号数据的音质回放。 原始音频信号数据在小波变换之前被重新整形为矩阵形式以对应于彩色图像文件的矩阵形式，而彩色图像文件在离散余弦变换之前经历格式转换。 变换后的音频信号数据和重新格式化的彩色图像的系数在进行逆矩阵重构和随后的逆小波变换之前被组合，以最终生成插入了彩色图像水印的音频信号。
