在opencv 2.4 for python中缺少冲浪

Question

I'm trying to instantiate a SURF object in python using OpenCV as described here 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 1

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
