error while using FREAK

Question

I'm trying to create Descriptor extractor using FREAK. but at the following line: freakExtractor = cv2.DescriptorExtractor_create('FREAK')

I get an error saying: freakExtractor = cv2.DescriptorExtractor_create('FREAK') AttributeError: 'module' object has no attribute 'DescriptorExtractor_create'

can someone tell me what is the exact problem and why i'm getting this error?

I'm using ubuntu 12.10 with opencv 2.4.3 and python 2.7.

Answer 1

I think,

cv2.DescriptorExtractor_create('FREAK') 

is not a part of python interface, just use the latest opencv for that then it will work or you simply can write the code in c++ which is availabe in that version in c++.
