I tried to match several images containing buildings using SIFT & SURF. The results I obtained were that SIFT was more accurate and gave a true match. By contrast SURF did not give me any match. I think the reason is that the building tiles/textures are the same. Can someone explain these results when it is generally said that SURF approximately equals SIFT in accuracy ?
Here's the test results:

I have another test but I cannot create more than 2 links. Also how would one recognize if the two images are matched?
