图像检索。通过计算所要检索的图像与图像库中的距离dis，dis最小者与检索图像同类。(image retrieval. Calculated to be indexed images and pictures of the dis the distance, the smallest dis with similar image retrieval.)

DWT的彩色水印嵌入算法，而且嵌入的水印附图像是彩色的。(DWT color watermark embedding algorithm, and the embedded watermark such as color drawings.)

SIFT算法提取关键点，SIFT算法提取关键点(SIFT algorithm to extract key points, SIFT algorithm to extract key points)

匹配算法，可以完美运行，对于初学者有着很好的参考价值(Matching algorithm, can be a perfect run, has a very good reference for beginners)

图像SURF特征提取，用于图像拼接和篡改检测，注释比较详细，程序很好理解(SURF feature extraction, image is used for image matching and tamper detection, comments are detailed, the program is easy to understand)

新的水下图像对比度增强和分割算法（实现对比度的增强和图像分割，内容包括：新的水下图像对比度增强算法、水下图像的分割算法--2008a）(The new underwater image contrast enhancement and segmentation algorithm (implemented contrast enhancement and image segmentation, including: new underwater image contrast enhancement algorithms, underwater image segmentation algorithm- 2008a))

说明：  实现超级像素的图像分割程序源代码，代码很全面(The realization of super-pixel image segmentation source code, code is very comprehensive)

opencvsharp检测圆

对图像处理后，将图像中的目标边缘提取出来，然后添加到原图像上(After image processing, the image of the target edge extracted, and then added to the original image)

说明：  小波变化是对傅里叶变换和短时傅里叶变换的一个突破，其改变就在于，将无限长的三角函数基换成了有限长的会衰减的小波。(Wavelet transform is a breakthrough of Fourier transform and short-time Fourier transform. Its change lies in that the infinite trigonometric function base is replaced by the finite attenuation wavelet.)
