In this paper, multiple pedestrians tracking system using Histogram of Oriented Gradient and occlusion detection is proposed. The proposed system is applicable to Intelligent Surveillance System. First, we detect pedestrian in a image sequence using pedestrian's feature. To get pedestrian's feature, we make block-histogram using gradient's direction histogram based on HOG(Histogram of Oriented Gradient), after that a pedestrian region is classified by using Linear-SVM(Support Vector Machine) training. Next, moving objects are tracked by using position information of the classified pedestrians. And we create motion trajectory descriptor which is used for content based event retrieval. The experimental results show that the proposed method is more fast, accurate and effective than conventional methods.

Terrestrial digital multimedia broadcasting (TDMB) is a method of bringing multimedia images, radio, internet, and television to portable devices through terrestrial digital radio transmissions. TDMB related educations being carried out in colleges are focusing on developing firmware which enables users to choose a wanted service. TDMB transmission frame is made up of synchronization channel (SC), fast information channel (FIC), and main service channel (MSC). Services such as video, audio and date are transmitted in the form of subchannel in the MSC. FIC carries information related to each services and subchannels. This paper presents a TDMB frame analysis simulator for analyzing and displaying FIC data on PC. TDMB frame analysis simulator contains functions such as controlling TDMB receiver through USB, establishing the frequency, bringing FIC to PC, displaying ensemble ID and levels, and displaying informations related to services and subchannels. In addition to that, this simulator has a function of being able to store FIC date and subchannel data. This simulator being developed with C++ is expected to be used to view those data visually so that it helps students to understand the TDMB system better and bring about the educational motivation.

Growing worldwide interest in software and spread awareness of the need for education. A software-driven society realization strategy will achieve mandatory training on software. This policy will be applied from middle school students in 2015. Students who are interested in computers, like many positive responses, student learning may seem hard to have a negative reaction. Thus, the present obligation as simple in practice education only and discarded before actually lost interest awarded a systematic education does not work properly, but rather that education could happen to entirely discard turn our attention. Accordingly, what you need is to have a systematic training from the basics that I need to worry about software that can recognize easy and fun. In this paper, we propose a hardware and basic software that allows you to proceed software training more easy and efficient as it can be modified and applied to the program in the production unit to learn programming tools and programming languages.

폭력의 발생 원인은 다양하고 그 표현 방식도 여러 가지 양상으로 나타나지만 인간의 기저에 갖고 있는 일반적 원인은 욕구불만이다. 욕구불만의 해소가 이루어지지 않은 상태에서의 인간은 항상 폭력성이 잠재되어있는 상태가 된다고 볼 수 있다. 윌리엄 맥두걸은 본능이 인간행동에 동기를 부여하는 가장 중요한 요인이며, 지각과 정서보다 동기의 힘을 강조했다. 사람은 본능이 동기를 부여해 준 것을 지각하고 적절한 대상이 지각되면 그 대상은 행동을 자극하는 감정변화를 일으킨다. 이러한 검정변화를 충동이라 할 수 있는데 지그문트 프로이드는 인간의 많은행동이 불합리한 본능적 충동에 바탕을 둔다고 보고 있다. 충동은 대개 생리적인 긴장, 결핍,또는 불균형상태에 뿌리는 두며 충족되어야 할 절박한기본 욕구로 유기체에 행동을 강요한다. 충동은 선천적이며, 기본적인 생리적 욕구와 직접적으로 관련된 충동과 학습을 통한 모방충동, 약물복용의 반복적으로 인한 양물중독이 있고, 성취, 활동, 친화, 호기심, 배설, 탐구, 조작, 모성애, 고통회피, 성애, 수면 등 인간의 생활에 반영되는 거의 모든 욕구를 포함한다. 따라서 욕구의 해소를 위해 무엇인가를 해야만 하는 인간은 욕구의 억압상태나 좌절상태에서 심한 분노와 폭력의 충동을 느끼게 된다. 현대 심층심리학은 어린이들이 말을 충분히 자유자재로 구사하기 전에 겪고 억누르게 된 무시무시한 분노의 환상을 가지고 있는데,. 공포예술의 무시무시한 영상들이 결부되어있다는 것이 밝혀졌다. 픽카드(P.M. Pickard)에 의하면 어린아이는 그들의 내적 현실을 외적 현실을 적응시키려는 힘겨운 투쟁 속에 근친상간적 갈등, 흡혈귀, 살인, 식인 등 끔찍한 환상을 겪는 것 간다고 한다. 청소년기는 사회적 부적응기로서 현실과 어릴 적 꿈꿔왔던 이상과의 괴리감에서 오는 당혹과 분노가 발생되는데, 이 시기에 많은 청소년들이 극단적인 선정적인 폭력성에 탐닉하게 되는 경향이 있다. 현실은 결코 아름답지 못하고, 행복하게 살 수 없다는 것에 대한 깨달음에서 기인한다. 욕구불만의 강도가 심해질수록 폭력성은 더욱 강하게 나타나는데 개인에게서 뿐만 아니라 가족, 동료, 사회 단체나 종교, 국가간에도 집단적으로도 발생하게 된다. 사회적으로 볼 때 폭력은 용인되는 것이 아니므로 도덕적으로 절제를 하거나 상대방과 적절한 타협과 조정을 필요로 한다. 그러나 절제의 한계를 넘어선다고 생각되거나, 조정의 노력이 불가능하거나, 실패했을 때 폭력적인 행동으로 나타나게 된다. 리차즈(I.A Richards)는 분노와 공포는 일단 겉잡을 수 없는 경향이 있다고 하면서 오늘날 폭력에 대한 요구가 일상의 정서 생활에 있어, 억압을 통한, 빈곤함을 반영하고 있지 않은지 생각해봐야 할 것이라고 충고한다.

We present a new biometric identification system based on multi-view features of teeth using principal components analysis(PCA). The multi-view features of teeth consist of the frontal view, the left side view and the right side view. In this paper, we try to stan the foundations of a dental biometrics for secure access in real life environment. We took the pictures of the three views teeth in the experimental environment designed specially and 42 principal components as the features for individual identification were developed. The classification for individual identification based on the nearest neighbor(NN) algorithm is created with the distance between the multi-view teeth and the multi-view teeth rotated. The identification performance after rotating two degree of test data is 95.2% on the left side view teeth and 91.3% on the right side view teeth as the average values.

In this paper, we design a ubiquitous home automation system for Korean domestic 33-Pyung Apartment based on USN environment. The core of this home automation system is to give Home the 'Intelligence' so that the house can analyze and memorize the occurrences and react spontaneously on the user requirements by means of the World Model, USN, and LBS etc. Ultimately, the resident of this intelligent home might access all of these ubiquitous environments without any feelings about the equipments and peripherals. The methods of user identification, image recognition, and the ultrasonic sensors locations have been applied to Korean domestic 35-Pyung Apartment, but they will be easily generalized to be an extended model because of the flexibility of the World Model. which are confirmed by the imaginary scenario presented at the end of the main left.

This paper is concerned with development of system to detect an obstructive vehicle which is an essential prerequisite for autonomous driving system of ASV(Advanced Safety Vehicle). First, the boundary of driving lanes is detected by a Kalman filter through the front image obtained by a CCD camera. Then, lanes are recognized by regression analysis of the detected boundary. Second, parameters of road curvature within the detected lane are used as input in error-BP algorithm to recognize the driving direction. Finally, an obstructive vehicle that enters into the detection region can be detected through setting detection fields of the front and lateral side. The experimental results showed that the proposed system has high accuracy more than 90% in the recognition rate of driving direction and the detection rate of an obstructive vehicle.
