Locating a Defined Area Edge Detection

Hey there,

I would like to know where the cropped parts from a cropped picture coincide in the original picture. I think one of the best way is based on edge detection. I have 3 RGB image.

1- Orijinal Image

2-Cropped Image

3-Croppedd and Rotated Image

What i have done:

1- I change the color space RGB to HSV

2- I applied the edge detection using edge function with Canny method

3- Now i have 3 image.

What i am looking for

1- How to find my cropped images in original image
