This data augmentation tool adds gaussian noise to the training images such the testing becomes robust against these noises.

Gaussian noise is a statistical noise having probability density function equal to normal distribution. Normal distribution is characterized by its mean and variance.

This defines the range of variance for the gaussian distribution. The amount of noise present in the image is directly proportional to the variance.

The mean of the gaussian distribution tells us the point at which the value of the distribution is highest.

Setting the mean to 0 means that the peak of the curve will be located at the origin.

```
import albumentations as albu
from PIL import Image
import numpy as np
transform =albu.GaussianNoise(var_limit=(10,50),mean=0,p=0.5)
image = np.array(Image.open('/some/image/file/path'))
image = transform(image=image)['image']
\# Now the image is transformed and ready to be accepted by the model
