Abstract

In this paper, we propose a method of embedding images into a speech signal. An image is embedded in the high frequency band above 16 kHz of the speech signal to be difficult to perceive for humans. In the proposed method, the image is embedded after being binarized by the error diffusion method. When the image is embedded, we apply an iterative phase restoration method to avoid noise generation. We also investigate a compensation method for an extracted image whose quality degrades due to transmission channel characteristics. Simulation and real-environmental experiments showed that the proposed method significantly improved the quality of the extracted image on the receiver side.

语音信号中的二进制图像嵌入与还原

本文提出了一种在语音信号中嵌入图像的方法。图像被嵌入到语音信号 16 kHz 以上的高频段中，使人类难以感知。在本文提出的方法中，图像是通过误差扩散法进行二值化后嵌入的。图像嵌入后，我们采用迭代相位恢复法来避免噪声的产生。我们还研究了一种补偿方法，用于补偿因传输信道特性而导致质量下降的提取图像。仿真和实际环境实验表明，所提出的方法显著提高了接收端提取图像的质量。
