# To correct tilted images
import cv2 as cv
import numpy as np

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

# these points are related to the edges of the object in perspective[use Paint]
topL, topR, bottomL, bottomR = [74,296],[215,167],[519,425],[525,232]

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

input_coord = np.float32([topL, topR, bottomL, bottomR]) #the edges's points
output_coord = np.float32([[0,0],[w,0],[0,h],[w,h]]) # the image's borders

# transform from coordinates
Matrix = cv.getPerspectiveTransform(input_coord, output_coord) 

# warps the perspective of image outputting an image of size w,h 
output = cv.warpPerspective(image, Matrix, (w,h))

cv.imwrite("output.jpeg", output) # to save the image
cv.imshow("output", output)
cv.waitKey(0)
cv.destroyAllWindows()
