Real-time marker-less hand tracking is of increasing importance in human-computer
interaction. Robust and accurate tracking of arbitrary hand motion is a challenging problem …

Pattern lock is widely used for identification and authentication on Android devices. This
article presents a novel video-based side channel attack that can reconstruct Android …

This study presents a smart homecare surveillance system, which utilizes sound-steered
cameras to identify behavior of interest. First of all, to detect multiple source locations, a new …

With the irruption of inexpensive depth sensor devices, hand gesture tracking has become a
topic of great interest. Two main problems to face respect other tracking algorithms are the …

Hand gestures are an important type of natural language used in many research areas such
as human-computer interaction and computer vision. Hand gestures recognition requires the …

A new vision-based framework and system for human–computer interaction in an
Augmented Reality environment is presented in this article. The system allows the users to …

A sketch-based image retrieval often needs to optimize the tradeoff between efficiency and
precision. Index structures are typically applied to large-scale databases to realize efficient …

This paper presents an analysis of the design of classifiers for use in a hierarchical object
recognition approach. In this approach, a cascade of classifiers is arranged in a tree in order …

The visual analysis of human manipulation actions is of interest for eg human-robot
interaction applications where a robot learns how to perform a task by watching a human. In …

Performance on tests in which there is control over reporting (eg, cued recall with the option
to withhold responses) can be characterized by four parameters: free-and forced-report …
