WebOpenCV has an algorithm called SIFT that is able to detect features in an image regardless of changes to its size or orientation. This property of SIFT gives it an advantage over other feature detection algorithms which fail when you make transformations to an image. Here is an example of code that uses SIFT: 1. 2. WebIt can be seen from Figure 10 that point feature extraction and matching takes 30 ms if SURF and FLANN algorithms are adopted, which has little impact on real-time performance of the system but has better positioning accuracy and stability (see Figures 13 and Figure 14).
