One of the most advanced routines in picture editing. Remove undesirable parts from pictures.

Matlab辅助激光光学分析与应用，多说无益，用则拿之(Matlab-assisted laser optics analysis and applications, more than just words to get the use of the)

SDV-Hop算法的工作主要体现在对平均每跳距离做了二次修正。(SDV-Hop algorithm is mainly reflected in the average distance per hop secondary correction.)

说明：  可以方便地进行1,2范数的优化计算。具体针对稀疏恢复问题，最小二乘问题，约束优化问题的求解等。(It is convenient to optimize the calculation of 1,2 norms. Specifically for sparse recovery problem, least squares problem, constrained optimization problem and so on.)

图像处理与分析——偏微分方程方法，热方程去噪模型的演示代码。(Image processing and analysis- method of partial differential equations, heat equation denoising model demo code.)

This function removes random, high frequency noise originating from the electrodes. a) First, we use a simple low-pass filter. b) Second, we apply Donoho s method by writing the code. c) Third, we simply apply Matlab s thr function. It should be noted that the considered mother wavelet is Symmlet8.
