Feature descriptor comparison report

Feature descriptor comparison report
Sharing my research work of behavior of several types of feature descriptors. This article is an update of old "Comparison of feature descriptors" post. I've added a brand new ORB feature descriptor to the test suite, also SIFT descriptor included as well. And a new version of LAZY descriptor present in this test too.

A battle of three descriptors

I think developers and research guys who works with object recognition, image registration and other areas that uses keypoint extraction can find this post useful. Recently (from 2.4.2) a new feature descriptor algorithm was added to OpenCV library. FREAK descriptor is claimed to be superior to ORB and SURF descriptors, yet it's very fast (comparable to ORB). Also people in comments on my blog mentioned BRISK descriptor which is also new and more efficient than SURF. Well, finally i find a time to compare them and publish my research results.

Introduction

This post will be very similar to OpenCV comparison reports i made in past. Although those reports were published years ago, they are still somewhat actual. For this test i decided to rewrite the whole testing framework from scratch. The source code will be available soon. But for now, let me explain what i did to fi
