Data Set Used
Local spatio-temporal features and bag-of-features representations have become popular for action recognition. A recent trend is to use dense sampling for better performance. While many methods claimed to use dense feature sets, most of them are just denser than approaches based on sparse interest point detectors. In this paper, we explore sampling with… (More)
—This paper discusses a 2(1/2)-D tracking method allowing real-time recovery of the three-dimensional (3-D) position and orientation of a head moving in its image plane. The described method uses a two-dimensional (2-D) elliptical head model, region-and edge-based matching algorithms, and a linear Kalman filter estimator. The resulting motion tracking… (More)
—This paper discusses a neuro-fuzzy controller for sensor-based mobile robot navigation in indoor environments. The control system consists of a hierarchy of robot behaviors.
—This paper proposes a new approach to solve the problem of real-time vision-based hand gesture recognition with the combination of statistical and syntactic analyses. The fundamental idea is to divide the recognition problem into two levels according to the hierarchical property of hand gestures. The lower level of the approach implements the posture… (More)
—Extrapolating the von Neuman's random-pulse machine concept, the paper discusses the multibit random-data representation and shows how it can be used for the modular design of robust instrumentation for real-time statistical parameter estimation and especially of hardware neural networks.
The recent advances in technology and mobile computing led to the rapid growth of networked 3D streaming applications. Due to the limited network bandwidth of the client server approach, research works are now turning toward mobile ad-hoc networks (MANET)-based streaming. MANET-based streaming is considered challenging due to the limitation of the wireless… (More)
—Digital watermarking is becoming more and more important for protecting the authenticity of multimedia objects as they become easier to copy, exchange, and modify. Several watermarking schemes have been proposed in recent years, but most of them deal with still images, only some being extended over to the temporal domain for video watermarking. But again… (More)
Digital signage is a very attractive medium for advertisement and general communications in public open spaces. In order to add interaction capabilities to digital signage displays, special considerations must be taken. For example, the signs' environment and placement might prevent direct access to conventional means of interaction, such as using a… (More)
