Article No.: 20
DOI: 10.1145/2423636.2423638

This study proposes an efficient localization scheme in wireless sensor networks. The proposed scheme utilizes mobile anchors and is based on ring overlapping. In a wireless sensor network, the nodes that know their locations are called reference...

Data embedding in image-media using weight-function on modulo operations
Hung-Min Sun, Chi-Yao Weng, Shiuh-Jeng Wang, Cheng-Hsing Yang
Article No.: 21
DOI: 10.1145/2423636.2423639

Multimedia hiding system is to embed message behind the specified media, but it is still kept normal in media representations via human sensitive organizations without causing imperceptibility. In this article, we propose a data hiding system by...

Artistic image generation for emerging multimedia services by impressionist manner
Sanghyun Seo, Seungtaek Ryoo, Kyunghyun Yoon
Article No.: 22
DOI: 10.1145/2423636.2423640

In this article, we propose the rendering framework for painting-like image generation and general system architecture for mobile device. Especially, we focused on a color division method for generating neo-impressionist images. The French...

ENFFiS: An enhanced NAND flash memory file system for mobile embedded multimedia system
Sang Oh Park, Sung Jo Kim
Article No.: 23
DOI: 10.1145/2423636.2423641

Since the typical erase cycle limit of a NAND flash memory's block is about 1,000,000, flash memory should be erased as evenly as possible; otherwise, file system hot spots will soon be worn out. This forces a NAND flash memory file system to scan...

Thermal-aware task scheduling in 3D chip multiprocessor with real-time constrained workloads
Jiayin Li, Meikang Qiu, Jian-Wei Niu, Laurence T. Yang, Yongxin Zhu, Zhong Ming
Article No.: 24
DOI: 10.1145/2423636.2423642

Chip multiprocessor (CMP) techniques have been implemented in embedded systems due to tremendous computation requirements. Three-dimension (3D) CMP architecture has been studied recently for integrating more functionalities and providing higher...

Video search and indexing with reinforcement agent for interactive multimedia services
Anand Paul, Bo-Wei Chen, Karunanithi Bharanitharan, Jhing-Fa Wang
Article No.: 25
DOI: 10.1145/2423636.2423643

In this study, we present a video search and indexing system based on the state support vector (SVM) network, video graph, and reinforcement agent for recognizing and organizing video events. In order to enhance the recognition performance of the...

Physical activity recognition using multiple sensors embedded in a wearable device
Yunyoung Nam, Seungmin Rho, Chulung Lee
Article No.: 26
DOI: 10.1145/2423636.2423644

In this article, we present a wearable intelligence device for activity monitoring applications. We developed and evaluated algorithms to recognize physical activities from data acquired using a 3-axis accelerometer with a single camera worn on a...
