DCT去噪，利用MATLAB实现DCT去噪，从而提高图片质量。(DCT de-noising, de-noising using MATLAB realize DCT, thereby improving image quality.)

说明：  利用matlab调用cplex实现一个简单的优化例子，例子中对参数设置有详细的说明，非常适合初学者，因为上传不能小于1k，所以复制了一下。(Using MATLAB to call CPLEX to realize a simple optimization example. In the example, the parameter setting is explained in detail, which is very suitable for beginners)
