This paper proposes a low-cost method for counting people based on blob detection and blob tracking. Here background subtraction is used to detected blob and then the blob is classified with its width and height to specify that the blob is a person. In this system we first define the area of entry and exit point in the video frame. The counting of people starts when midpoint of the people blob crosses the defined point. Finally, total number of people entry and exit from the place is displayed. Experiment result of this proposed system has high accuracy in real-time performance.

In this paper the situation requiring emergency rescue team from the endangered person, using the structure of the signal with a transmitter that provides the service. Given real-time map information based on a directional antenna to the transmitter of the received value, and moving the location of the forecast to move the tracker to the location of the transponder, the algorithm offers. Location tracking algorithm implemented in the simulator to actually do the verification report which will show whether the performance of the show.

기존의 명화를 인터랙티브화하여 관람자에 반응하는 영상을 제작 하였다. 명화와 자신이 함께한다는 새로운 개념을 시도하였으며 동시에 관람자의 색을 인지하여 명화가 바뀌는 시스템을 기획 하였다. 샤갈(Marc Chagall)의 작품 속에 관람자가 투영되고 동시에 작품의 정체성에 맞는 다른 BGM으로 상황을 연출한다. 관람자가 움직이면 작품에 모션이 투영되지만 움직임이 없는 상황엔 자연스럽게 작품만이 보여 진다. 영화 4작품은 '칼라트랙킹'에 의해 관람자의 레드(Red), 그린(Green), 블루(Blue)에 각각 반응 하도록 제작 하였다.

Radio frequency identification(RFID) is a system of technology that transmits digitally coded identity information in the form of a unique serial number of an object or person wirelessly, using radio waves. The primary use of RFID has been in asset tracking. This makes it highly useful across various industries for effective and efficient conduct of different business processes like supply chain management (SCM). As the use of RFID expands, the use of this technology is observed in such industries as transportation, traffic payment, hospital and medical care, education, and retail. Although this technology offers immense potential, it faces multifarious roadblocks, particularly in developing countries like India. Under this backdrop, this paper attempts to present an overview of the use and application RFID technology in India with a highlight on business-ecosystem for RFID in India. We also present various technical and non-technical challenges in the implementation of RFID in India.

This paper presents an active assisted-living system in wireless sensor and actor network (WSAN) in which the mobile robot roles an actor. In order to provide assisted-living service to the elderly people, position recognition of the sensor node attached on the user and localization of the mobile robot should be performed at the same time. For the purpose, we use received signal strength indication (RSSI) to find the position of the person and ubiquitous sensor nodes including ultrasonic sensor which performs both transmission of sensor information and localization like global positioning system. Active services are moving to the elderly people by detecting activity sensor and visual tracking and voice chatting with remote monitoring system.

Door to door service is a typical method for individual parcel deliveries. In the current delivery information system, a delivery person manually input the information of many delivery results, which causes inefficiency and difficulties of tracking deliveries. This study suggests an enhanced delivery information system which has the following two characteristics. Firstly, a tagged RFID transmits the delivery result information to the main server by just collecting RFID at a place of destination. Secondly, with the characteristics of rewritable method, the collected RFID is to be input new information and tagged to other parcels.

The aim of applying Functional Electrical Stimulation (FES) is to restore a person's motor function by directly supplying the controlled electrical currents to the site of the paralyzed muscles. However, most clinically utilized FES systems have adapted an open-loop control scheme. Recently the closed-loop control scheme has been considered for setting up the FES system, but due to the inherent nonlinearities in the musculoskeletal system, the nonlinearities were not fully compensated and it caused the oscillatory responses for tracking the output variables. In this study, a nonlinear controller model that has two inverse compensation units is proposed with the compromising feedback linearization method and this will eventually be used to design the FES control system for stimulating a knee joint musculoskeletal system.

In recent years the space where a robot works has been expanding to the human space unlike traditional industrial robots that work only at fixed positions apart from humans. A human in the recent situation may be the owner of a robot or the target in a robotic application. This paper deals with the latter case; when a robot vision system is employed to monitor humans for a surveillance application, each person in a scene needs to be identified. Humans, however, often move together, and occlusions between them occur frequently. Although this problem has not been seriously tackled in relevant literature, it brings difficulty into later image analysis steps such as tracking and scene understanding. In this paper, a probabilistic neural network is employed to learn the patterns of the best dividing position along the top pixels of an image region of partly occlude people. As this method uses only shape information from an image, it is simple and can be implemented in real time.

Recently, in Korea the birthrate is declining and the average life span has been increasing. Thus, compared to the previous periods nowadays, older people are required to work. Even elderly people are rejoining the workforce. Korean companies set the retirement age between 55 and 60 years of age, however, accidents occur frequently. Thus, it becomes necessary to evaluate the ability of the elderly person. Since the required function of the worker varies from job to job the evaluation of the capability must also be conducted according to the desired functions. One of the methods used in this study is the continuous control knob to evaluate the tracking control ability to investigate the relationship of manual dexterity and age. The result of the study Indicates that the manual dexterity decreases with age. However, there are differences among individuals. The individuals lifestyle affected the manual dexterity of that individual. As a result, a company may use the manual dexterity as an measure to evaluate the elderly persons work ability.

The purpose of this paper is to develop simulations that can be used for virtual education in dentistry. This development goal is to allow dental students to learn the necessary surgical techniques at the point of their choice, not going into the operating room, away from time, space, and physical limits. In this paper configuration, the optimization method is applied convergent, and when the operation of the VR contents is performed, the content data is extracted from the interaction analysis formed in the VR engine, and the data is processed by the content algorithm. It also computes events and dental operations generated within the 3D engine programming and generates corresponding events through data processing according to the input signal. The visualization information is output to the HMD using the rendering information. In addition, the operating room environment was constructed by studying lighting and material for actual operating room environment. We applied the ratio of actual space to virtual space and the ratio between character and actual person to create a spatial composition at a similar rate to actual space.
