我们将从另一个图像中减去一个图像并取差值的绝对值。 # Calculate the difference between the imagesdiff=cv2.absdiff(gray1,gray2) 阈值差异图像 为了更好地可视化两个图像之间的差异,我们将阈值差异图像。我们将使用cv2 库中的threshold() 函数来阈值图像。 # Threshold the difference image_,thresh=cv2.thresh...

Then we are converting both images to grayscale format. gray1 = cv2.cvtColor(img1, cv2.COLOR_BGR2GRAY) gray2 = cv2.cvtColor(img2, cv2.COLOR_BGR2GRAY) Now it's time to find the absolute difference between the two images (arrays). diff = cv2.absdiff(gray1, gray2) cv2.imshow("diff...

The latter aims to check whether two operands contain the same data. Note: To learn more about the difference between identity and equality, check out Python ‘!=’ Is Not ‘is not’: Comparing Objects in Python. Here’s a summary of Python’s identity operators. Note that x and y are...
The difference between is and ==is operator checks if both the operands refer to the same object (i.e., it checks if the identity of the operands matches or not). == operator compares the values of both the operands and checks if they are the same. So is is for reference equality ...
