摘要
研究加密图像隐藏信息准确识别技术。在图像中,如果加密信息隐藏在图片的噪声中,噪声信号和隐藏信息敏感信号混合在一起,将造成隐藏信息的敏感信号图谱特征发生形变。传统算法多是通过采集图像中的敏感信息图谱特征完成检测的,噪声信号和隐藏信息混合在一起,造成隐藏信息图谱可识别特征发生突变,导致识别准确率下降。提出一种逆向隐藏变换算法的图像隐藏信息识别技术,对图像进行置乱处理,运用干扰清除技术完成识别。实验证明,这种算法能够避免由于噪声信号和隐藏信号混合造成的隐藏信息特征发生形变的缺陷,保证了图像隐藏信息识别的准确率。
The military encryption image hiding information accurately identify technology.In the military the image of the encrypted information hiding in the picture if the noise,the noise signal and information hiding sensitive signal mixed together,will cause the hidden information sensitive signal deform spectroscopic characteristics.More than traditional algorithm is through the acquisition of image of sensitive information map features can identify the completion of the inspection,noise signal and information hiding mix together,cause hidden information map can identify when deformed features,cause identification accuracy decline.Put forward a kind of reverse hidden transform algorithm military image hidden information identification technology,scrambling to military image processing,the use of interference clear finish recognition technology.Experiments show that the algorithm can avoid the noise signal and the hidden cause of mixed signal characteristics hidden information deform defects,ensure the military image hiding information identification accuracy
