Efficient adaptive non-maximal suppression algorithms for homogeneous spatial keypoint distribution

This is the implementation of the paper "Efficient adaptive non-maximal suppression algorithms for homogeneous spatial keypoint distribution" that is published in Pattern Recognition Letters (PRL). Alternatively, see TL;DR version.

Algorithm Overview

While competing ANMS methods have similar performance in terms of spatial keypoints distribution, the proposed method SSC is substantially faster and scales better:

Retrieve 10% Retrieve 40% Retrieve 70%

Here is how proposed ANMS method visually compares to traditional methods: TopM | Bucketing | SSC (proposed)

TopM Bucketing SSC

Related algorithms that are implemented in this repository are:

  • "Visual Odometry based on Stereo Image Sequences with RANSAC-based Outlier Rejection Scheme" - bucketing
  • "Multi-Image Matching using Multi-Scale Oriented Patches" - original ANMS
  • "Efficiently selecting spatially distributed keypoints for visual tracking" - more efficient ANMS

For more details about the algorithm, experiments as well as the importance of homogeneously distributed keypoints for SLAM please refer to the paper.
