看到的一个有关图像锐化的MATLAB代码(See a MATLAB code for the image sharpening)

this folder contain universal dataset for classification

学习Matlab的仿真工具，而且有丰富的例子供大家参考(learning Matlab simulation tool, but a wealth of examples for your consideration.)

快速计算一维信号的塔式谱峭度图，选择谱峭度最大值区间，方便确定所需滤波器中心频率及带宽。(Computes the fast kurtogram of signal x.This fast algorithm uses a pyramidal decomposition of the signal into a user-specified number of levels (a good choice is nlevel = 8). The first level is the classical kurtosis of the signal, the second level is the spectral kurtosis in 2 octaves, the third level the spectral kurtosis in 4 half-octaves, etc. Non-integer levels refer to divisions into third octaves. Here below is an illustration on how the frequency band is successively split when increasing the level)
