Abstract: Distinctive Image Features from Scale-Invariant Keypoints

TLDR
The Scale-Invariant Feature Transform (or SIFT) algorithm, is a highly robust method to extract, and consequently match, distinctive invariant features from images that can then be used to reliably match objects in diering images.
Abstract
The Scale-Invariant Feature Transform (or SIFT) algorithm, is a highly robust method to extract, and consequently match, distinctive invariant features from images. These features can then be used to reliably match objects in diering images. The algorithm was rst proposed by Lowe [12] and further developed to increase performance, resulting in the classic paper [13] that served as foundation for SIFT, which has played an important role in robotic and machine vision in the past decade.

Localized contourlet features in vehicle make and model recognition

TL;DR: A novel localized feature detection method in Contourlet transform domain that is capable of increasing the classification rates up to 4%, as compared to the previously proposedcontourlet based vehicle MMR approach in which the features are non-localized and thus results in sub-optimal classification.

Distinctive Image Features from Scale-Invariant Keypoints

TL;DR: 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.

Object recognition from local scale-invariant features

TL;DR: Experimental results show that robust object recognition can be achieved in cluttered partially occluded images with a computation time of under 2 seconds.

A Combined Corner and Edge Detector

TL;DR: The problem the authors are addressing in Alvey Project MMI149 is that of using computer vision to understand the unconstrained 3D world, in which the viewed scenes will in general contain too wide a diversity of objects for topdown recognition techniques to work.

SURF: speeded up robust features

TL;DR: A novel scale- and rotation-invariant interest point detector and descriptor, coined SURF (Speeded Up Robust Features), which approximates or even outperforms previously proposed schemes with respect to repeatability, distinctiveness, and robustness, yet can be computed and compared much faster.
Journal ArticleDOI

A performance evaluation of local descriptors

TL;DR: 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.
