To work with OpenCV from python, you need to install it first:
pip install opencv-python
After we import cv2 we can directly work with images like so:
import cv2
img = cv2.imread("doc_brown.png")
The Normal Distribution
Diving deeper into data science I started to brush up my knowledge about math especially statistics.
The Mother of all Distributions
The normal distribution was formulated by Carl Friedrich Gauß in 18XX and can be implemented in Python like the following :
def normal_distribution(x, mu=0, sigma=1):
sqrt_two_pi = math.sqrt(2*math.pi)
return math.exp(-(x-mu)**2 / 2 / sigma**2) / sqrt_two_pi * sigma
