Hi

i need to evaluate SIFT and SURF with some criteria that mentioned on these papers "A comparison to SIFT PCA-SIFT and SURF" which can be found here : http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.301.7041

and "Evaluation of Local Detectors and Descriptors for Fast Feature Matching" which you can download it from miksik.co.uk/papers/miksik2012icpr.pdf .

i noticed that each paper defined repeatibility differently. in first paper it has been defined

and in second paper

which one should i use for SIFT and SURF evaluation?

and also in OpenCV i found a function named evaluateFeatureDetector. (simple code: cv::evaluateFeatureDetector(img_1c, img_2c, h12, &key_points_1, &key_points_2, repeatability, corrCounter);)

i want to know that which formula OpenCV use for finding repeatibility. also how can i find Precision-recall in OpenCV.

Best Regards

Edited : find evaluateGenericDescriptorMatcher method which can be used for finding recalls. don't know how to use it. also couldn't find any documentation for it.
