中文摘要：
提出了一种基于小波包分解的彩色图像隐秘检测算法，算法中利用了一种彩色图像线性预测模型，根学小波包分解系数绝对值与线性预测值的时数误差生成特征向量，采用Fisher线性判别进行分类识别。实验证明此算法时彩色隐秘图像具有较高的识别率。
英文摘要：
A new colour images steganography algorithm which based on wavelet packet decomposition is given.In the algorithm we use one colour images linear magnitude prediction model of wavelet packet decomposition coefficients,according as the log error between the actual coefficient and the predicted coefficient magnitudes yield statistics.These statistics form the feature vector,and then we take advantage of the Fisher liner discrimination to dlscriminate.The experimental results show that the algorithm has higher discriminating rate.
