说明：  比较硬阈值、软阈值法图像去噪，并提出折中阈值法去噪(Comparison of hard thresholding, soft thresholding image denoising, and put forward a compromise threshold denoising)

图像压缩经典EZW算法 可提初学者学习参考使用(image compression EZW)

采用National Instruments 视觉算法库，雷赛运动控制卡，映美精相机 检测手机LOG(Using National Instruments vision algorithms library, Lemire motion control card, Imaging camera detects the phone LOG)

用于图像拷贝检测的图像匹配，提取图像的SIFT特征点，构成图像的特征。(For image copy detection of image matching, image SIFT feature point extraction, and then sift feature point the image characteristics)

小波域稀疏表示，正交匹配追踪算法压缩感知重建(wavelet transform Compressive sensing)

对彩色图像进行小波融合，融合后图像在视觉上有了很大的改善。(Color images of wavelet fusion images visually a great improvement.)

实现了20000*20000以上的大tiff格式遥感图像的读写和显示，用于遥感图像处理(Achieve a 20,000* 20,000 or more large remote sensing image tiff format to read and write and display for remote sensing image processing)

softcast的2d dct实现，先对图像转灰度图，得到的亮度信号矩阵做DCT 变换(softcast of 2d dct implementation, the first image to grayscale, luminance signal obtained by DCT transformation matrix do)

说明：  用matlab 实现的图像滤波，，，，，，，，，，(Image filtering realized by MATLAB,,,,,,,,,,)

曲面拟合法是数字图像相关方法中的一种亚像素求解算法，通过此方法可以求得被测物体表面的全场位移。(Surface fitting method is a sub- pixel method in digital image correlation method.)
