Nowadays, digital content is widespread and simply redistributable, either lawfully or
unlawfully. For example, after images are posted on the internet, other web users can modify …

If a physical object has a smooth or piecewise smooth boundary, its images obtained by
cameras in varying positions undergo smooth apparent deformations. These deformations …

In the past decade, SIFT is widely used in most vision tasks such as image retrieval. While in
recent several years, deep convolutional neural networks (CNN) features achieve the state …

This note is devoted to a mathematical exploration of whether Lowe's Scale-Invariant
Feature Transform (SIFT)[21], a very successful image matching method, is similarity …

Efficiency is of great importance for image retrieval systems. For this pragmatic issue, this
paper proposes a fast image retrieval framework to speed up the online retrieval process. To …

Unsupervised near-duplicate detection has many practical applications ranging from social
media analysis and web-scale retrieval, to digital image forensics. It entails running a …

Most of current fingerprint indexing schemes utilize features based on global textures and
minutiae structures. To extend the existing technology of feature extraction, this paper …

Wireless Sensor Networks (WSNs) have enjoyed dramatic developments over the last
decade. The availability of CMOS cameras and microphones enlarged the scope of WSNs …

We propose a shot-based interest point selection approach for effective and efficient near-
duplicate search over a large collection of video shots. The basic idea is to eliminate the …

Among the vast numbers of images on the web are many duplicates and near-duplicates,
that is, variants derived from the same original image. Such near-duplicates appear in many …
