matlab实习卷积运算。很高兴与大家分享此代码。(Matlab internship convolution operators. Very pleased to share with you that this code.)

振动消噪代码，包括白噪声、有色噪声、粉色噪声的生成；相关系数法消噪、小波软阈值消噪、互相关系数消噪三种方法对比。(Gaussian white noise, Gaussian colored noise and pink noise have been processed to verify the validity of the algorithm. we also compared the proposed method with the correlation coefficient method and wavelet soft threshold noise reduction methods. the results show that the proposed method can be performed on a variety of signal noise reduction, which is better than the correlation coefficient method and wavelet soft threshold noise reduction methods.)

matlab在工程数学中的应用，适合初学者学习(matlab application of mathematics in engineering, suitable for beginners to learn)

egion growing approach is the opposite of the split and merge approach: An initial set of small areas are iteratively merged according to similarity constraints. Start by choosing an arbitrary seed pixel and compare it with neighbouring pixels. Region is grown from the seed pixel by adding in neighbouring pixels that are similar, increasing the size of the region. When the growth of one region stops we simply choose another seed pixel which does not yet belong to any region and start again.
