摘　　要：传统的通信图像处理方法存在载体图像恢复程度差的问题,为此,基于可逆信息隐藏算法的通信图像处理研究。采用建立坐标映射的方法,定位隐藏通信图像,将采集到的信息以十进制进行坐标定位。并以逆向思维获取对通信图像的解码秘钥,在传输网络中镶嵌解码秘钥,对通信图像进行获取,同时,基于数字化技术的应用,对获取的隐藏通信图像灰度转换,并使用傅里叶定理计算函数,恢复通信图像二值,输出处理图像。实验结果表明,所提方法可实现对通信图像的有效恢复,确保导出图像的有效性。Traditional communication image processing methods have the problem of poor restoration of carrier image.Therefore,the research of communication image processing based on reversible information hiding algorithm is proposed.The method of establishing coordinate mapping is used to locate the hidden communication image,and the collected information is located in decimal system.At the same time,based on the application of digital technology,the gray level of the obtained hidden communication image is converted,and the Fourier theorem is used to calculate the function to restore the binary value of the communication image and output the processing image.Experimental results show that the proposed method can effectively restore the communication image and ensure the effectiveness of the derived image.
