A new scale invariant feature detector and modified SURF descriptor
- Computer Science2010 Sixth International Conference on Natural Computation
A new scale invariant octagonal center-surround detector, named OCT, and a modified SURF descriptor named I-SURF descriptor are introduced, which have better performance than SURF and SIFT.
An Evaluation of Open Source SURF Implementations
- Computer ScienceRoboCup
Different SURF implementations written in C++ are evaluated and it is found that some implementations produce up to 33% lower repeatability and up to 44% lower maximum recall than the original implementation, while the implementation provided with the software Pan-o-matic produced almost identical results.

C-SURF: Colored Speeded Up Robust Features
- Computer ScienceISCTCS
The built C-SURF (Colored Speeded Up Robust Features) is more robust than the conventional SURF with respect to rotation variations and uses 112 dimensions to describe not only the distribution of Harr-wavelet responses but also the color information within the interest point neighborhood.
Fast Feature Matching by Coarse-to-Fine Comparison of Rearranged SURF Descriptors
- Computer ScienceIEICE Trans. Inf. Syst.
A fast matching method that rearranges the elements of SURF descriptors based on their entropies, divides SURF descriptorors into sub-descriptors, and sequentially and analytically matches them to each other is proposed.
Unbiased evaluation of keypoint detectors with respect to rotation invariance
- Computer ScienceIET Comput. Vis.
The most computationally complex detector, i.e. the SIFT performs best under rotation transformation of images, but the FAST and ORB detectors, while being less computationally demanding, perform almost equally well and can be viable choices in image processing tasks for mobile applications.
A fast, robust and low bit-rate representation for SIFT and SURF features
- Computer Science2011 IEEE International Symposium on Safety, Security, and Rescue Robotics
This work investigates low bit-rate representations based on a binarisation of SIFT and SURF features and is able to reduce the descriptor length by a factor of 8–32 and lifts the curse of dimensionality.
KPB-SIFT: a compact local feature descriptor
- Computer ScienceACM Multimedia
The produced KPB-SIFT descriptor is more compact as compared to the state-of-the-art, does not require pre-training step needed by PCA based descriptors, and shows superior advantages in terms of distinctiveness, invariance to scale, and tolerance of geometric distortions.
RSD-HoG: A New Image Descriptor
- Computer ScienceSCIA
A novel local image descriptor called RSD-HoG is proposed that performs better than many state of the art descriptors such as SIFT, GLOH, DAISY and PCA-SIFT and has rich, discriminative set of local information related to the curvature of the image surface.

Distinctive Image Features from Scale-Invariant Keypoints
- Computer ScienceInternational Journal of Computer Vision
This paper presents a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene and can robustly identify objects among clutter and occlusion while achieving near real-time performance.
PCA-SIFT: a more distinctive representation for local image descriptors
- Computer ScienceProceedings of the 2004 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2004. CVPR 2004.
This paper examines (and improves upon) the local image descriptor used by SIFT, and demonstrates that the PCA-based local descriptors are more distinctive, more robust to image deformations, and more compact than the standard SIFT representation.
A performance evaluation of local descriptors
- Computer ScienceIEEE Transactions on Pattern Analysis and Machine Intelligence
It is observed that the ranking of the descriptors is mostly independent of the interest region detector and that the SIFT-based descriptors perform best and Moments and steerable filters show the best performance among the low dimensional descriptors.
Multi-scale phase-based local features
- Computer Science2003 IEEE Computer Society Conference on Computer Vision and Pattern Recognition, 2003. Proceedings.
The results show that the phase-based local features lead to better performance than the other two approaches when dealing with common illumination changes, 2D rotation, and sub-pixel translation.
Indexing based on scale invariant interest points

This paper presents a new method for detecting scale invariant interest points. The method is based on two recent results on scale space: (1) Interest points can be adapted to scale and give…
Invariant Features from Interest Point Groups
- Computer ScienceBMVC
This work introduces a family of features which use groups of interest points to form geometrically invariant descriptors of image regions to ensure robust matching between images in which there are large changes in viewpoint, scale and illumi- nation.
Fast Approximated SIFT
- Computer ScienceACCV
A considerably faster approximation of the well known SIFT method by using efficient data structures for both, the detector and the descriptor and an analysis of the computational costs.
Object recognition from local scale-invariant features

Experimental results show that robust object recognition can be achieved in cluttered partially occluded images with a computation time of under 2 seconds.
Rapid object detection using a boosted cascade of simple features
- Computer ScienceProceedings of the 2001 IEEE Computer Society Conference on Computer Vision and Pattern Recognition. CVPR 2001
A machine learning approach for visual object detection which is capable of processing images extremely rapidly and achieving high detection rates and the introduction of a new image representation called the "integral image" which allows the features used by the detector to be computed very quickly.
