Question

Write a program that asks the user for the name of an image, the name of an output file. Your program should then save the upper right quarter of the image to the output file specified by the user. A sample run of your program should look like: Enter image file name: hunterLogo.png Enter output file: logOUR.png which would have as input and output: HUNTER ITER The City University of New York Hint: See sample programs from Lectures 3 and 6. Note: before submitting your program for grading, remove any commands that show the image (i.c. the ones that pop up the graphics window with the image). The program is graded on a server on the cloud and does not have a graphics window, so, the plt.show() and plt.imshow) commands will give an error. Instead, the files your program produces are compared pixel-by-pixel to the answer to check for correctness.

Answer 1

#inbuild modules are imported
import cv2
import numpy as np

#reading image from the pc
image = cv2.imread('hunterLogo.png')

#making a copy of the readed image
image_copy = np.copy(image)

#finding height and width of the image
height = image_copy.shape[0]
width= image_copy.shape[1]
half_width = (int)(width/2)
half_height = (int)(height/2)

#cropping the image using slicing
cropped_image = image_copy[0:half_height, half_width:width]

#saving the image using cv2 with 'logoUR.png'
cv2.imwrite('logoUR.png',cropped_image)
