YUV Quantization using VS2010

提取SIFT特征，进行特征提取和匹配，包括特征点的定位，特征点描述子的生成，特征点的匹配，(extract SIFT feature，and feature matching)

说明：  OpenCV FaceDetectDirectShow小波图像分割算法(Wavelet image segmentation algorithm)

对图像进行二维离散小波变换, 变换级数大于等于3级,然后进行阈值化处理(阈值约为10左右),再统计系数中0的个数（百分比表示）并进行重构, 最后计算重构图像的峰值信噪比(PSNR). (Two-dimensional discrete wavelet transform image transformed series is greater than or equal to 3, and then processing thresholding (threshold of about 10 or so), then statistical coefficient in the number (expressed as a percentage) and to reconstruct the final calculation reconstructed image of the peak signal-to-noise ratio (PSNR).)

任意切换各种颜色空间，包含大部分主流的颜色空间转换代码，可实现一键转换。(Arbitrary switching of various color spaces, including most of the mainstream color space conversion code, can achieve one key conversion.)

说明：  LSB替换隐写软件，该软件能把ASCII码嵌入到图像中，其载体图像是24位的BMP格式图像(LSB replaces steganography software, which can embed ASCII code into image, and its carrier image is 24 bit BMP format image)

这是图像拼接大神的在ICCVC上的PPT报告，思路清晰，受益匪浅，(PPT report in God s image stitching on ICCVC and clear thinking, benefit,)

为数字图像水印提供多种攻击方式，其中包括JPEG压缩、高斯低通滤波等多达十种攻击方式。(Offers a variety of attacks of digital watermarking ,including the jpeg compression, Gaussian low-pass filtering, up to ten different attacks)
