Using OpenCV for Image Similarity

Python
11

I did that, but I’m getting an error after resizing the images. If I don’t resize them then nothing prints out like before.

import cv2

img1 = cv2.imread("Test\i1.png")
img2 = cv2.imread("Test\i2.png")

img1 = cv2.bitwise_not(img1)
img2 = cv2.bitwise_not(img2)

img1 = cv2.resize(img1, (100, 200))
img2 = cv2.resize(img2, (100, 200))

pts_a = cv2.findNonZero(img1)
pts_b = cv2.findNonZero(img2)

hd = cv2.createHausdorffDistanceExtractor()
d1 = hd.computeDistance(pts_a, pts_b)

print(d1)

Error:
line 12, in <module> pts_a = cv2.findNonZero(img1) cv2.error: OpenCV(4.5.4) D:\a\opencv-python\opencv-python\opencv\modules\core\src\count_non_zero.dispatch.cpp:160: error: (-215:Assertion failed) src.channels() == 1 && src.dims == 2 in function 'cv::findNonZero'
