# Makes tilted objects in image appear straight
import cv2 as cv
import numpy as np

image = cv.imread("perspective1.jpeg")

# the coordinates of the object of interest inside the image (use Paint):
topleft, topright, bottomleft, bottomright = [74,296],[215,167],[519,425],[525,232]

w, h = 600, 600 # width and height of the image to generate

# Sets the coordinates of the object and the output frame:
input_coord = np.float32([topleft, topright, bottomleft, bottomright])
output_coord = np.float32([[0,0],[w,0],[0,h],[w,h]])

Matrix = cv.getPerspectiveTransform(i_coord, o_coord)
output = cv.warpPerspective(image, Matrix, (w,h))
cv.imwrite("perspective1_output.jpeg", output)

''' 
cv.imshow("output", output)
cv.waitKey(0)
cv.destroyAllWindows()
