In this paper, we present an active sampling method to speed up conventional pixel-wise background subtraction algorithms. The proposed active sampling strategy is designed to focus on attentional region such as foreground regions. The attentional region is estimated by detection results of previous frame in a recursive probabilistic way. For the estimation of the attentional region, we propose a...
To solve the problem of real-time object tracking under partial occlusions and non-rigid deformations, we propose a tracking method based on sequential Bayesian inference. The proposed method is mainly consisted of two parts: (1) modeling the target object using elastic structure of local patches for robust performance; and (2) efficient hierarchical sampling method to obtain an acceptable solution...
This paper introduces an integrated operational simulation framework designed for a virtual test-bed in Smart Grid, which has been under development in our research group. It can support an open access from remote side over Internet and simulate various scenarios for the development of operational policies. It consists of 4 components for testing (i) service operation policy and strategy, (ii) optimization...
Embedded software should be correctly developed so that it is be compliant with not only functional requirements but also real-time and resource constraints. However, those constraints are often dependent on execution environments that are sometimes revealed in late development phases. In this paper, we propose Timed and Resource-oriented Statecharts (TRoS) to analyze the time and resource-constrained...
In order to make the methods suitable to complex real-time systems (CRS), it is necessary to reduce the complexity of CRS with a large number of heavily interacting mobile agents over spatial-temporal space. To demonstrate the necessity of the reduction, this paper presents a new formal method, namely, calculus of real-time distribution, mobility, and interaction (CARDMI). In CARDMI, the spatial requirements...
