# 1. Open any image;
 
# 2. Build a kernel for sharpening an image
# (you will need to research this);
 
# 3. Apply this filter to the image.
 
import numpy as np
import cv2
from matplotlib import pyplot as plt
from matplotlib import image as image

I = cv2.imread("Lenna.png")
 
G = cv2.cvtColor(I, cv2.COLOR_BGR2GRAY)
 
k = np.array([[0,-1,0], [-1,5,-1], [0,-1,0]],
dtype=float)
 
F = cv2.filter2D(G,ddepth=-1,kernel=k)
 
cv2.imshow("image", F)
key = cv2.waitKey(0)

The second part of this lab was used to finish off our first modules .assignment.
