Local Image Features for Shoeprint Image Retrieval [PDF]

open access: yesProcedings of the British Machine Vision Conference 2007, 2007
This paper deals with the retrieval of scene-of-cri me (or scene) shoeprint images from a reference database of shoeprint images by using a n ew local feature detector and an improved local feature descriptor. Our approach is based on novel modifications and improvements of a few recent techniques in this area: (1) the scale a dapted Harris detector ...

Feature semantic alignment and information supplement for Text-based person search

open access: yesFrontiers in Physics, 2023
The goal of person text-image matching is to retrieve images of specific pedestrians using natural language. Although a lot of research results have been achieved in persona text-image matching, existing methods still face two challenges.

Automatic discovery of image families: Global vs. local features [PDF]

open access: yes, 2009
Gathering a large collection of images has been made quite easy by social and image sharing websites, e.g. flickr.com. However, using such collections faces the problem that they contain a large number of duplicates and highly similar images.

Image-Based Localization Using Hybrid Feature Correspondences [PDF]

open access: yes2007 IEEE Conference on Computer Vision and Pattern Recognition, 2007
Where am I and what am I seeing? This is a classical vision problem and this paper presents a solution based on efficient use of a combination of 2D and 3D features. Given a model of a scene, the objective is to find the relative camera location of a new input image.

DC-image for real time compressed video matching [PDF]

open access: yes, 2014
This chapter presents a suggested framework for video matching based on local features extracted from the DC-image of MPEG compressed videos, without full decompression. In addition, the relevant arguments and supporting evidences are discussed.

Flexible Spatial Configuration of Local Image Features [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2007
Local image features have been designed to be informative and repeatable under rigid transformations and illumination deformations. Even though current state-of-the-art local image features present a high degree of repeatability, their local appearance alone usually does not bring enough discriminative power to support a reliable matching, resulting in
