###Importing the OpenCV library
##import cv2
##from matplotlib import pyplot as plt
##
###Reading the image using imread() function
##image = cv2.imread('image.png')
##cv2.imshow("Amna",image)
### Extracting the height and width of an image
##h, w= image.shape[:2]
### Displaying the height and width
##print("Height = {}, Width = {}".format(h, w))

#####Reading the image using imread() function
##image = cv2.imread('image.png')
##### Extracting RGB values. Here we have randomly chosen a pixel by passing in 100, 100 for height and width.
##(B, G, R) = image[100, 100]
####
##### Displaying the pixel values
##print("R = {}, G = {}, B = {}".format(R, G, B))

###Importing the OpenCV library
##import cv2
#####Reading the image using imread() function
##image = cv2.imread('image.png')
### We will calculate the region of interest by slicing the pixels of the image
##roi = image[100 : 500, 200 : 700]
##cv2.imshow("roi",roi)

###Importing the OpenCV library
##import cv2
#######Reading the image using imread() function
##readimg = cv2.imread('image.png')
### resize() function takes 2 parameters, the image and the dimensions
##resize_IMG = cv2.resize(readimg, (800, 800))
##cv2.imshow("RESIZE",resize_IMG)

### Using the rectangle() function to create a rectangle.
##rectangle = cv2.rectangle(reading, (1500, 900), (600, 400), (70, 56, 0), 4)

## cv2.addWeighted is applied over the
## image inputs with applied parameters
##weightedSum = cv2.addWeighted(image1, 1, image2, 1, 0)
##
## the window showing output image
## with the weighted sum
##cv2.imshow('Weighted Image', weightedSum)
