This paper propose an adaptable block-based background modeling and real time image object detection algorithm. In training step, we present adaptable block-based background model that uses major color number to determine the block size. This background model can reduce the memory consumption, efficiently. In detection step, we use one pixel to compare with background model. Then, it can reduce processing...
The high development of medicine causes the world's population aging quickly. To resolve the problem with limited medical resources, constant monitoring of elders' activity of daily living is important. We propose an activity recognition system for smart home, so elders can live alone and their children can monitor their parents' living activity to achieve the concept of "Aging in Place"...
As a new computing model cloud computing provide users with services subversive with the aid of the vast resources on the Internet system. Cloud computing has been used in network storage, web search, e -mail application and other fields. In order to achieve the fairness of data distribution and improve the throughout and transmission rate, the cloud computing model based on multiservice access dynamic...
In this paper, we describe a novel 3D shape retrieval method based on new features. The features are extracted for 3D points based on a 2D attribute space which consists of two bidirectional 3D shape attributes, one of which along the shape surface direction and the other along the shape content direction perpendicular to the former. We define this features as Point Bidirectional Features (PBFs),...
Based on the Technology Acceptance Model (TAM) developed from the theory of reasoned action (TRA) and social psychology research by Davis (1989), this study models the use of the Internet-based modular object-oriented dynamic learning environment (Moodle) by students of the computer science department at Ming Chuan University (MCU), Taiwan. Apart from student demographics and background information...
Coordination refers to agents that coordinate their own behavior in an environment of finite resources to conform to individual benefits or group goals. Dependent agents use effective information connections for coordinating and adjusting resource distribution, thereby reaching agreements between dependent agents. However, during the process of coordination, an effective method of assessment is necessary...
OpenFlow is a new type of switch model in rapid development. This model supports the control of external policies to network process. Multi-table and multi-item group matching is the challenge in Openflow platform. Three-layer implementation model of Openflow switch is proposed in this paper. Openflow multi-table switching technique based on TCAM is studied, Iincluding the model of the multi-table...
Network Learning is becoming increasingly popular today. It is getting important to develop adaptive learning by social network that can be applied in intelligent e-learning systems, and provide learners with efficient learning paths and learning orders for learning objects. Therefore, we use the Rule-Space Model to infer reasonable learning effects of Blue-Red trees and their definitions through...
Background construction is the base of object detection and tracking for the machine vision system. Traditional background modeling methods often require complicated computations and are sensitive to illumination changes and shadow interference. In this paper, we propose a block-based background modeling method, which fully utilizes the color and texture characteristics of each incoming frame. The...
The Industrial Ethernet is promising for the implementation of a Cloud Computing based control system. However, numerous standard organizations and vendors have developed various Industrial Ethernets to satisfy the real-time requirements of field devices. This paper presents a real-time reconfigurable protocol stack to cope with this challenge, by introducing the architecture with a core of dynamic...
In this paper, we propose a Gaussian mixture model (GMM) based voice conversion method using explicit feature transform models. A piecewise linear transform with stochastic bias is adopted to present the relationship between the spectral features of source and target speakers. This explicit transformations are integrated into the training of GMM for the joint probability density of source and target...
