上传一张图片，这是在做图像水印研究时常用的一张lina图(image used in watermarking)

可以计算图像结构相似性，评价图像质量(Similarity of image structure can be calculated and image quality can be evaluated)

图像的分水岭分割及标记分块。是进行图像处理的有利工具(Image segmentation and marking a watershed block. Is a powerful tool for image processing)

Matching Pursuit 算法，该算法能够把Gabor原子集合，用线性组合表示，能够降低运算量。(Matching Pursuit algorithm, which can Gabor atomic collection, using a linear combination that can reduce computational complexity.)

运用图像处理，运用滤波，闭运算，腐蚀，膨胀进行一维码即条形码的识别(The use of image processing, the use of filtering, closed computing, corrosion, expansion of one-dimensional code, that is, bar code identification)

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.)
