Surf missing in opencv 2.4 for python
Question: I'm trying to instantiate a SURF object in python using OpenCV as described
[here](http://docs.opencv.org/modules/nonfree/doc/feature_detection.html#surf)
but this happens:

    
    
    >>> import cv2
    >>> cv2.__version__
    '2.4.0'
    >>> cv2.SURF()
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    AttributeError: 'module' object has no attribute 'SURF'
    

Does anyone know why this happens or if SURF is missing from the Python
version of OpenCV?


Answer: It is a regression which should be fixed in the next library update.

But SURF is not really absent. You still can access it via the generic
wrappers:

    
    
    surf_detector = cv2.FeatureDetector_create("SURF")
    surf_descriptor = cv2.DescriptorExtractor_create("SURF")

**Update:** `cv2.SURF()` is restored in OpenCV 2.4.1
