代码说明:

  Jsteg隐写算法[23][24]由D. Upham提出,该算法将秘密信息嵌入在量化后的DCT系数的LSB上,但值为-1、0、+1的DCT系数例外。提取秘密信息时,也只是将隐藏信息的图像中不等于-1、0、+1的量化DCT系数的LSB取出即可(steganography of jsteg)

    首先通过多分辨率分解法提取高频边缘,然后分别对每层的高频边缘进行非线性插值得到新的高频边缘,接着对高频边缘进行高通滤波得到等强后的高频边缘,最后对增强后的高频边缘进行修正。再在对增强的图像进行对比度拉伸,从而达到增强的目的!(First of all, through the extraction of multi-resolution decomposition of high-frequency edge, and then were on the edge of each high-frequency non-linear interpolation to be the new high-frequency edge, and then the edge of the high-frequency high-pass filter to be strong, such as after the high-frequency edge, and finally on the brink of enhanced high-frequency be amended. Again in contrast enhanced image stretching, so as to achieve the purpose of enhancing!)

  • 人脸识别 MATLAB代码
    说明:  使用pca方法对图像进行特征提取,对训练集的20个人的共一百张人脸进行训练,使用adaboost算法生成强分类器,可以对测试集的人脸图片进行识别,且识别率较高(The PCA method is used to extract the features of the image, and the training is carried out for a total of 100 faces of 20 people in the training set. The AdaBoost algorithm is used to generate a strong classifier, which can recognize the face images in the test set with a high recognition rate)
