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.

Brian 2.1: A socially assistive robot for the elderly and cognitively impaired

TL;DR: The number of older adults who have difficulties performing self-care and independent-living activities increases significantly with the prevalence of cognitive impairment, and the total worldwide cost of dementia was estimated to be US$604 billion in 2010.

Efficient classification with sparsity augmented collaborative representation

TL;DR: It is shown that sparseness explicitly contributes to improved classification, hence it should not be completely ignored for computational gains and an efficient classification method is proposed based on combined representation based on dense and sparse representation.

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.

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.
