  • 재생기에서 MP4 파일을 재생하기 위해서는 Drawing 정보와 Routing 정보가 필요하다. 기존의 저작도구에서의 객체 Naming은 그 객체와는 상관없이 단순히 문자열과 숫자의 조합으로 되어 있고 실제 화면상에 기술되는 객체의 ID값을 부여하는 방법이었다. 객체 Naming을 구현하는 객체 ID 설정이 이러한 방법이었기 때문에 재생기에서 객체 정보를 구하려면 Scene 그래프를 반복해서 검색하는 load가 발생한다. 본 논문에서는 이러한 load를 줄이기 위해서 비트 연산을 이용한 각 객체의 ID를 부여함으로써 각 객체에 속하는 Attribute의 ID가 자신의 실제 객체의 ID를 추론할 수 있는 방법으로 객체에 대한 Naming을 구현하였다. 이러한 객체 Naming 기법으로 설정된 객체의 ID값은 비트 연산과 시프트 연산을 이용해서 객체 정보를 구할 수 있기 때문에 Scene 그래프 탐색 load를 줄일 수 있다.

  • Recently, Construction business is changing from on the ground to underground space because of deficit of developing space, creation of green space and of incremental of land compensation expenses. Meanwhile, 3D Topographic, Marine and Cadastral maps need to have Spatial Interrelation. Also, understanding of the information is also needed. Spatial information object registration system is impossible to contact and understanding intelligence mutually because the former one is managed as automatic ID system. Therefore, 3D Object information ID System of underground space is managed based on Object Identifier. Construction of Spatial information integration ID System is required and it will offer Division Code (Ground, Index, Underground) and depth information. We are defined and classified Under Spatial Information in this paper. Moreover, we developed the integration ID System based on UFID for cadastral information Construction. We supposed underground spatial information DB Construction and a developed the way of exploiting 3D cadastral information system through the study. The research result will be the base data of Standard ID system, DB Construction and system Development of National spatial data which is considered together with spatial interrelation.

  • 다중 객체 추적 기술은 스포츠, 문화 예술 공연, VR 등 여러 방송 콘텐츠에서 자주 사용되고 있다. 방송 영상 안에 등장하는 여러 객체들은 객체간 상호작용에 의해 가려짐, 사라짐 (Occlusion) 등의 현상이 빈번하게 발생하고, 이 경우 기존에 추적되어온 객체들의 ID 가 소실되거나 교환되는 문제가 발생한다. 본 논문에서 더 강인한 다중 객체 추적을 위해, 주 개체 뿐만 아니라 주 개체에 종속되는 하위 개체 또한 함께 추적하는 개체-쌍-추적 기법을 제안한다. 한 쌍으로 묶인 주 개체와 종속 개체의 추적 정보와 매칭 정보는 상호보완적으로 사용되어, 소실 및 교환된 ID 도 복원할 수 있는 가능성을 높일 수 있다. 본 논문에서는 재인지 성능 향상을 위한 개체 쌍 추적 기법을 기술하였고, 성능 평가를 통해 제안 방법이 재인지 성능 향상에 기여할 수 있음을 확인하였다.

  • As computing paradigm of the next generation, Ubiquitous Computing has emerged owing to growing of the Internet and computer networking technologies, and RFID (Radio Frequency Identification) which is the core technology to achieve(realize,actualize) the Ubiquitous Computing environment, is being noticed. MIT's Auto-ID Center has proposed PML(Physical Markup Language) which is based on XML (Extensible Markup Language), is a standard language for describing physical objects, in order to interchange of data between each of these RFID application systems. The PML defines only core parts to describe physical objects, but on the other hand the other parts to be needed in practical application have to be defined with extended definitions separately. In this paper, therefore, the object information data model was designed, which defines the type of the object in order. to process electronic tag information in the RFID application service based on PML Core of Auto-ID Center and is applicable to the distribution service parts.

  • 유비쿼터스 환경의 도래와 함께, 사용자는 자신이 가입한 서비스별로 또는 사용자와 연관된 객체별로 서로 다른 ID(가명)를 사용할 수 있다. 기존의 ID 기반 암호 스킴은 하나의 ID에 하나의 독립된 복호키가 부여되기 때문에, ID의 개수가 증가하면 상대적으로 복호키의 개수도 증가한다 그러나 ID 별로 별도의 복호키를 생성 관리하는 것은 비밀키의 유지 관리에 따른 효율서의 저하를 가져오므로, 서로 다른 ID를 사용하되, 하나의 복호키를 사용하여 ID를 이용한 정보의 기밀성을 제공할 수 있는 방법이 요구된다. 본 논문에서는 사용자가 복수의 ID를 생성하여 사용하되, 각각의 서로 다른 ID로 암호화된 암호문을 단 하나의 복호키를 이용하여 복호할 수 있는 새로운 pairing 기반 암호 스킴을 제안한다.

  • Recently, the amount of video data collected from smartphones, CCTVs, black boxes, and high-definition cameras has increased rapidly. According to the increasing video data, the requirements for analysis and utilization are increasing. Due to the lack of skilled manpower to analyze videos in many industries, machine learning and artificial intelligence are actively used to assist manpower. In this situation, the demand for various computer vision technologies such as object detection and tracking, action detection, emotion detection, and Re-ID also increased rapidly. However, the object detection and tracking technology has many difficulties that degrade performance, such as re-appearance after the object's departure from the video recording location, and occlusion. Accordingly, action and emotion detection models based on object detection and tracking models also have difficulties in extracting data for each object. In addition, deep learning architectures consist of various models suffer from performance degradation due to bottlenects and lack of optimization. In this study, we propose an video analysis system consists of YOLOv5 based DeepSORT object tracking model, SlowFast based action recognition model, Torchreid based Re-ID model, and AWS Rekognition which is emotion recognition service. Proposed model uses single-linkage hierarchical clustering based Re-ID and some processing method which maximize hardware throughput. It has higher accuracy than the performance of the re-identification model using simple metrics, near real-time processing performance, and prevents tracking failure due to object departure and re-emergence, occlusion, etc. By continuously linking the action and facial emotion detection results of each object to the same object, it is possible to efficiently analyze videos. The re-identification model extracts a feature vector from the bounding box of object image detected by the object tracking model for each frame, and applies the single-linkage hierarchical clustering from the past frame using the extracted feature vectors to identify the same object that failed to track. Through the above process, it is possible to re-track the same object that has failed to tracking in the case of re-appearance or occlusion after leaving the video location. As a result, action and facial emotion detection results of the newly recognized object due to the tracking fails can be linked to those of the object that appeared in the past. On the other hand, as a way to improve processing performance, we introduce Bounding Box Queue by Object and Feature Queue method that can reduce RAM memory requirements while maximizing GPU memory throughput. Also we introduce the IoF(Intersection over Face) algorithm that allows facial emotion recognized through AWS Rekognition to be linked with object tracking information. The academic significance of this study is that the two-stage re-identification model can have real-time performance even in a high-cost environment that performs action and facial emotion detection according to processing techniques without reducing the accuracy by using simple metrics to achieve real-time performance. The practical implication of this study is that in various industrial fields that require action and facial emotion detection but have many difficulties due to the fails in object tracking can analyze videos effectively through proposed model. Proposed model which has high accuracy of retrace and processing performance can be used in various fields such as intelligent monitoring, observation services and behavioral or psychological analysis services where the integration of tracking information and extracted metadata creates greate industrial and business value. In the future, in order to measure the object tracking performance more precisely, there is a need to conduct an experiment using the MOT Challenge dataset, which is data used by many international conferences. We will investigate the problem that the IoF algorithm cannot solve to develop an additional complementary algorithm. In addition, we plan to conduct additional research to apply this model to various fields' dataset related to intelligent video analysis.

  • P&ID((Piping and Instrument Diagram) is a key drawing in the engineering industry because it contains information about the units and instrumentation of the plant. Until now, simple repetitive tasks like listing symbols in P&ID drawings have been done manually, consuming lots of time and manpower. Currently, a deep learning model based on CNN(Convolutional Neural Network) is studied for drawing object detection, but the detection time is about 30 minutes and the accuracy is about 90%, indicating performance that is not sufficient to be implemented in the real word. In this study, the detection of symbols in a drawing is performed using 1-stage object detection algorithms that process both region proposal and detection. Specifically, build the training data using the image labeling tool, and show the results of recognizing the symbol in the drawing which are trained in the deep learning model.

  • Various kinds of data broadcasting services can be offered using a return-channel in digital broadcasting TV compared to analog services. In these data broadcasting environments, several data(associated with TV broadcasting programs, or not) are provided to the TV audiences except for audio/video broadcasting data. In this paper, a structure of data manager for data/object carousel, based on data broadcasting protocols, was proposed for data broadcasting services using a return-channel, and were supported to the production technologies of DTV contents. These contents application techniques for DTV will be implemented with this data manager in MPEG2-TS data broadcasts using PID(Packet ID).

  • 지속적인 딥러닝 기반의 영상처리 기술의 발전으로 객체분류나 객체검출 문제에 대해서 뛰어난 성능 보이고 있다. 하지만 객체추적 문제에서는 성능이 좋은 추적기는 실시간 동작이 불가능하고 딥러닝 기반의 객체추적도 단일 객체에만 고려한 기법이 많기 때문에 개선할 필요가 있다. 전처리로 검출된 객체영역과 kalman filter를 통해 예측된 추적영역 간의 embedding feature 비교를 통해 동일인물인지 판단하여 고유 ID를 부여하고 추적한다. 객체끼리 교차하거나 가려지는 상황에서 추적을 실패하게 되는데 이 후에 지속적인 추적을 위해 IoU 비교를 통해 후보 추적기로 남겨두는 과정을 거친다. 실험 결과 실시간 동작여부와 객체끼리 교차하거나 프레임 밖으로 나갔다가 다시 나타나는 경우에도 추적이 가능함을 확인하였다.
