Hu的七个不变矩在图像处理，尤其是特征提取方面是很重要的一个概念。本代码实现了图像的7个不变矩的计算和输出。( Hu s 7 moment invariants is significant in image processing,especially in feature seletcion. This code calculate them.)

说明：  dct域的图像数字水印，将水印图像信息隐藏在DCT系数的中频部分。(DCT domain image watermarking, the watermark image information hidden in the intermediate frequency part of DCT coefficients.)

说明：  利用DELPHI编写的摄像头程序，摄像头采用USB摄像头(Using the camera program written by DELPHI, the camera uses a USB camera.)

散乱密集点的曲面拟合，在国外matlab论坛上下载的，看了一下，写的有点繁琐，还是比较不错的(Scattered dense surface point Fitting in foreign matlab forum, download, read about, write a bit cumbersome, it is quite good)

主要适用于图像增强的客观质量评价，效果比较好；其实熵值就是求图像的相似度(Mainly applied to the objective of image quality evaluation, the effect is better; In fact, the entropy is to find the image similarity)

用VB写的画出波纹的程序(Written by VB painted corrugated procedures)

数字图像处理 小波处理 ，去噪音，比基于傅里叶变换的去噪方法好。 含噪信号经过预处理，然后利用小波变换把信号分解到各尺度中，在每一尺度下把属于噪声的小波系数去掉，保留并增强属于信号的小波系数，最后再经过小波逆变换恢复检测信号。(The noisy signal is pre-processed, then the signal is decomposed into different scales by wavelet transform. The wavelet coefficients belonging to noise are removed at each scale, and the wavelet coefficients belonging to the signal are retained and enhanced. Finally, the detected signal is restored by inverse wavelet transform. It is better than the denoising method based on Fourier transform.)

icp算法C++实例，用于点集的配准，实现两片点云数据的拼接(icp algorithm C++ instance, used for the registration point set to achieve splice two pieces of point cloud data)

说明：  基于MATLAB的行人检测。直接运行imhogtrace主程序，即可得到运行结果。针对不同的图像，需要调整参数，我放的这张图，虽然效果不好，但是可以提供参考意义(Pedestrian detection based on MATLAB. Run the main program of imhogtrace directly to get the running result. For different images, parameters need to be adjusted. Although the effect of this picture I put is not good, it can provide reference significance)
