This paper proposes a modified slotted random anti-collision algorithm to improve the read efficiency of anti-collision algorithm for the EPC global UHF Class-1 Generation-2 RFID standard. In this standard, the slotted random anti-collision algorithm which is a dynamic frame slotted ALOHA algorithm is specified to solve this problem. Also, the Q-algorithm with a key parameter C is adopted to dynamically...
To improve the coding efficiency of intra frame, a quad tree-based variable block size coding structure which is flexible to adapt to various texture characteristics of images and up to 35 intra prediction modes are adopted in the latest High Efficiency Video Coding (HEVC) standard. To further alleviate the encoder computation load, this paper proposes a fast intra mode decision algorithm based on...
With the development of communications and network technologies, video streaming service is becoming increasingly important. However, in the transmission of high compressed video, bit-stream is easily damaged by channel errors which will lead to the decline of the video sequence. Error concealment is an effective approach to reduce the influence in error-prone network and notably improve the video...
Multi-target tracking is a complex problem including time-varying number of targets and their states in the presence of data association uncertainty and clutter. In this article, we develop a novel implementation of Sequential Monte Carlo filter with a new improved partial resampling strategy in random finite sets framework. This algorithm provides an approach to increase diversity of particles and...
Activity recognition with triaxial accelerometer embedded in mobile phone is an important research topic in pervasive computing field. The research results can be widely used in many healthcare or data mining applications. Numerous classification algorithms have been applied into the activity recognition tasks. Among these algorithms, ELM (Extreme Learning Machine) shows its advantages in generalization...
The latest High Efficiency Video Coding (HEVC) standard could achieve the highest coding efficiency compared with all existing video coding standards. However, the computational complexity is increased dramatically because all the possible combinations of the mode candidates are calculated in order to find the optimal rate distortion (RD) cost using Lagrange multiplier. In order to save the coding...
The purpose of this research is to investigate the factors influencing satisfaction on e-tax filing (e-Revenue) of SMEs in Thailand. The data were collected from 415 respondents using the service. The website service quality dimensions in this study consist of information quality, system quality and service quality. The related hypotheses were tested using structural equation modeling. The researcher...
Most current studies concerning appliance recognition focus on single appliance recognition, but for general home users, it is universal to simultaneously switch on and off multiple electric appliances. Therefore, this study discusses the recognition of a multi-appliance load, and aims to establish recognition sample data, while reducing the packet transmission quantity and computation complexity...
