title: Sift vs Surf. Which is more accurate?
body: <p>I am testing object to do <strong>Feature Matching</strong> with Sift and Surf with C++ &amp; OpenCV. </p>
  
  <p><strong>Surf</strong> claims to be faster and <strong>Sift</strong> claims can detect many keypoints than Surf. I want to determine which algorithm is the most accurate.</p>
  
  <p>But I am confused to determine the accuracy in terms of time, or the matching keypoint. Can someone explain to me how do I determine which algorithm is the most accurate? And from which factor I determine its accuracy ?</p>
