用matlab实现的基于小波变换的图像增强去噪-(achieved using Matlab based on wavelet transform image enhancement and denoising)

Implement the K nearest neighbor algorithm by your own instead of using available software. 2. Use K-fold cross validation to generate training and testing datasets. You should try different K values (3~8) to see how they affect your result. 3. Train the classifier using your training dataset, and test the classifier using your testing dataset. 4. Repeat the experiment (Step 2 and Step 3) 30 times. For each time, you need to record the training data accuracy and testing data accuracy. Finally, you can obtain the average training data accuracy and average testing data accuracy.

说明：  永磁同步电机(PMSM)的矢量控制仿真模型，速度环采用滑模变结构控制，仿真波形较好。(The vector control simulation model of permanent magnet synchronous motor (PMSM) adopts sliding mode variable structure control in speed loop, and the simulation waveform is good.)
