This paper presents a novel robust people counting system based on fusing the depth and vision data. Conventional algorithms utilize the monoscopic or stereoscopic vision data to count people. However, these vision-based people counting methods often fail due to occasional illumination change and crowded environment. In the proposed algorithm, both the top-view vision and depth images are captured...
In current world, the semantic Web is not just a medium for information and records carrying, but growing communities for people sharing knowledge. With rapid updating Webs, many Websites or pages died away due to lack for awareness of importance of Web archive. The demand of establishing Web archive system is pressing for. This paper is concerning the construction of an NTU (Nanyang Technological...
This paper proposes a novel multiple watermarking scheme for different purposes: to notify the copyright owner with a reversible visible watermark in the region of interest (ROI) of the original image, and to protect the copyright with an invisible watermark in the remaining part of the image. It can fully remove the visible watermark from the dual watermarked image and restore the ROI. The invisible...
The conventional SVD-based watermarking has been proved to be flawed by protocol attacks. An image watermarking algorithm is proposed based on media hash. Instead of using randomly Gaussian sequence as watermark, a meaningful text message modulated by media hash sequence is used. Theoretical analysis results show that the proposed algorithm solves the problem of protocol attack, while keeping all...
This paper is concerned with the problem of Hinfin filter design for a class of linear uncertain systems with time-varying delay. The uncertainty parameters are supposed to be time-varying, unknown, but bounded, which appear affinely in the matrices of system model. Our proposed robust Hinfin filter is a switching-type filter, in which the filter parameters are tuned in a switching manner via a switching...
An adaptive neural network control (ANNC) is proposed for a class of strict-feedback uncertain nonlinear systems with unknown system nonlinearities and unknown virtual control gain nonlinearities. Combining the dynamic surface control (DSC) technique with minimal-learning-parameters (MLP) algorithm, a systematic procedure for synthesis of ANNC is developed based on the universal approximation of neural...
Range query in Peer-to-Peer networks based on Distributed Hash Table (DHT) is still an open problem. The traditional way uses order-preserving hashing functions to create value indexes that are placed and stored on the corresponding peers to support range query. The way, however, suffers from high index maintenance costs. To avoid the issue, a scalable blind search method over DHTs - recursive partition...
