I'm trying a simple thing like detector = cv2.SIFT() and get this bad error detector = cv2.SIFT() AttributeError: 'module' object has no attribute 'SIFT' I do not understand that because cv2 is installed. cv2.__version__ is $Rev: 4557 $ My system is Ubuntu 12.04. Maybe someone has got the same problem and could help me. EDIT: Long story short, testypypypy.py : import cv2 detector = cv2.SIFT() ERROR: Traceback (most recent call last): File "testypypy.py", line 3, in <module> detector = cv2.SIFT() AttributeError: 'module' object has no attribute 'SIFT If I take SURF it works because SURF is in

How to use SIFT algorithm to compute how similar two images are?

问题 I have used the SIFT implementation of Andrea Vedaldi, to calculate the sift descriptors of two similar images (the second image is actually a zoomed in picture of the same object from a different angle). Now I am not able to figure out how to compare the descriptors to tell how similar the images are ? I know that this question is not answerable unless you have actually played with these sort of things before, but I thought that somebody who has done this before might know this , so I posted
