Butterworth-hpf

Code for simulation of Fermi Pasta Ulam problem

基于Matlab 平台根据反馈数字逻辑给出了m 序列的计算机生成源程序和m 序列的基本性质的考察代码。可根据输入的八进制 本原多项式系数生成相应的m 序列。上机结果验证了程序的正确性和有效性(Matlab-based platform based on feedback digital logic m-sequence are given computer-generated source code and the basic properties of m-sequence code visits. According to the octal input primitive polynomial coefficients generate the m-sequence. The machine results validate the correctness and effectiveness of the program)

Compression Denoising enhanced procedures for your reference. Include: digital image data display matrix and its Fourier transform two-dimensional discrete cosine transform image compression method using gray-scale transformation of the contrast-enhanced images using two-dimensional median filter function by medfilt2 of salt and pepper noise image filtering using MATLAB The function affected by noise interference filter2 images mean filter Adaptive Image Filtering Wehner use five kinds of different gradient method to enhance image sharpening images of high-pass filtering and mask treatment using Butterworth (Butterworth) low pass filter noise by smoothing the images deal with the use of Butterworth (Butterworth) high-pass filter for sharpening images treatment
