## Introduction | ||
|
||
This is yet another Python implementation of Empirical Mode | ||
Decomposition (EMD). The package contains many EMD variations and | ||
intends to deliver more in time. | ||
|
||
### EMD variations: | ||
* Ensemble EMD (EEMD), | ||
* Image decomposition (EMD2D), | ||
* "Complete Ensemble EMD" (CEEMDAN) | ||
* different settings and configurations of vanilla EMD. | ||
|
||
*PyEMD* allows to use different splines for envelopes, stopping criteria | ||
and extrema interpolation. | ||
|
||
### Available splines: | ||
* Natural cubic [default] | ||
* Pointwise cubic | ||
* Akima | ||
* Linear | ||
|
||
### Available stopping criteria: | ||
* Cauchy convergence [default] | ||
* Fixed number of iterations | ||
* Number of consecutive proto-imfs | ||
|
||
### Extrema detection: | ||
* Discrete extrema [default] | ||
* Parabolic interpolation | ||
|
||
## Installation | ||
|
||
### Recommended | ||
|
||
Simply download this directory either directly from GitHub, or using | ||
command line: | ||
|
||
> \$ git clone <https://github.com/laszukdawid/PyEMD> | ||
Then go into the downloaded project and run from command line: | ||
|
||
> \$ python setup.py install | ||
### PyPi | ||
|
||
Packaged obtained from PyPi is/will be slightly behind this project, so | ||
some features might not be the same. However, it seems to be the | ||
easiest/nicest way of installing any Python packages, so why not this | ||
one? | ||
|
||
> \$ pip install EMD-signal | ||
## Example | ||
|
||
More detailed examples are included in the | ||
[documentation](https://pyemd.readthedocs.io/en/latest/examples.html) or | ||
in the | ||
[PyEMD/examples](https://github.com/laszukdawid/PyEMD/tree/master/example). | ||
|
||
### EMD | ||
|
||
In most cases default settings are enough. Simply import `EMD` and pass | ||
your signal to instance or to `emd()` method. | ||
|
||
```python | ||
from PyEMD import EMD | ||
import numpy as np | ||
|
||
s = np.random.random(100) | ||
emd = EMD() | ||
IMFs = emd(s) | ||
``` | ||
|
||
The Figure below was produced with input: | ||
$S(t) = cos(22 \pi t^2) + 6t^2$ | ||
|
||
 | ||
|
||
### EEMD | ||
|
||
Simplest case of using Ensemble EMD (EEMD) is by importing `EEMD` and | ||
passing your signal to the instance or `eemd()` method. | ||
|
||
```python | ||
from PyEMD import EEMD | ||
import numpy as np | ||
|
||
s = np.random.random(100) | ||
eemd = EEMD() | ||
eIMFs = eemd(s) | ||
``` | ||
|
||
### CEEMDAN | ||
|
||
As with previous methods, there is also simple way to use `CEEMDAN`. | ||
|
||
```python | ||
from PyEMD import CEEMDAN | ||
import numpy as np | ||
|
||
s = np.random.random(100) | ||
ceemdan = CEEMDAN() | ||
cIMFs = ceemdan(s) | ||
``` | ||
|
||
### EMD2D | ||
|
||
Simplest case is to pass image as monochromatic numpy 2D array. As with | ||
other modules one can use default setting of instance or more explicitly | ||
use `emd2d()` method. | ||
|
||
```python | ||
from PyEMD import EMD2D | ||
import numpy as np | ||
|
||
x, y = np.arange(128), np.arange(128).reshape((-1,1)) | ||
img = np.sin(0.1*x)*np.cos(0.2*y) | ||
emd2d = EMD2D() | ||
IMFs_2D = emd2d(img) | ||
``` | ||
|
