本代码用matlab实现了图像的Jpeg编解码，使我的毕业设计，在这里与大家共享。(The code is implemented using matlab Jpeg image codec, so my graduation, and share here.)

实现DCT变换和FFT变换的图像压缩， 比较两者性能的差异(The DCT transform and FFT transform image compression)

这是典型的图像分割Livewire算法的源码 结合OPENCV，配置一下就可以用了(This is a typical source image segmentation algorithm Livewire combination OPENCV, can be used to configure what)

说明：  首先对指纹图像进行预处理，包括图像的分割，增强，二值化，细化。对细化后的图像进行特征点的提取，最后通过细节特征匹配完成指纹的识别。(Firstly, the fingerprint image is preprocessed, including image segmentation, enhancement, binarization and thinning. The refined image is extracted by feature points, and the fingerprint recognition is completed by minutiae feature matching.)

去噪，一个非常好的去噪源代码，简单好用，设置方便(Denoising, denoising source code is a very good, easy to use and easy set up)

说明：  基于内容的CNN图像检索，编写语言为matlab(CNN Image Retrieval, matlab)

利用非局部特性并结合低秩解法的图像降噪算法，速度很快(Nonlocal properties combined with low rank Solution image noise reduction algorithm, fast)

利用迭代残差插值的去马赛克算法，进一步减小估计误差，得到更准确的全彩色图像，性能很不错。(Iterative interpolation residuals demosaicing algorithm to further reduce the estimation error, more accurate full-color images, the performance is very good.)

image compression using dwt and dct

说明：  matlab实现三维重建，代码书写规范，运行稳定(Matlab to achieve three-dimensional reconstruction, code writing standard, stable operation)
