Repeatability experiment with real images

In this experiment we count the number of features extracted using the LB approach and compared them to the features extracted using SIFT. We use a real image and a pi/2 rotated version of this image. We count the number of points with a distance smaller than 2 pixels between the extracted features and the projection of the rotated points from the original image.
