In general, background subtraction based methods are used to detect the moving objects in visual tracking applications. In this paper we employed background subtraction based scheme to detect the temporarily stationary objects. We proposed two schemes for stationary object detection and we compare those in terms of detection performance and computational complexity. In the first approach we used single background and in the second approach we used dual backgrounds, generated with different learning rates, in order to detect temporarily stopped object. Finally, we used normalized cross correlation (NCC) based image comparison to monitor and track the detected stationary object in a video scene. The proposed method is robust with partial occlusion, short time fully occlusion and illumination changes, as well as it can operate in real time.

Marketing communication is becoming a critical element in today's competive retail environment. Consumers are better educated and discriminating in their choices. Especially, now in the totally opened Korean market situation, establishing proper retail marketing strategy faces many challenge and require special attention. In this study, various promotion media application strategies are mentioned in order to help retailers who need to develop their own promotion plan. Among the media mix, xisual merchandising is becoming effective communication system for retail promotion. Because of its complex development process, retailers and professionals both need to understand the theoretical background of VMD and application method. As a guide in developing systems for each use, it might have some limitations due to the method of research and data related to researcher's choice. In spite of above mentioned limitations, this study will serve as a practical guide for the retailers who wishes to achieve marketing goals in order to survive in this competitive retail situation.

The recent advances in digital imaging and computing technology have resulted in a rapid accumulation of digital media in the personal computing and entertainment industry. In addition, large collections of such data already exist in many scientific application domains such as the geographic information systems (GIS), digital library, trademark imaging, satellite imaging and medical imaging. Thus, the need for content-based retrieval from visual media, such as image and video data, is ever increasing rapidly in many applications.

In this study, I would like to conduct a study on the design of chat UX between fandom and idol. The 1:多 form of message exposure method between idols and fandom was studied and the optimal exposure form and speed were tested. Based on the results of the experiment, 30 sentences were selected per second among various options, and based on this, the results were applied to the actual Universe platform to facilitate communication between idols and fans.

Deep learning has made rapid progress in recent years and is affecting various fields and industries. The art field cannot be an exception, and in this paper, we would like to explore and experiment and analyze research fields that creatively generate 2D images in 3D from a visual arts and engineering perspective. To this end, the original image of the domestic artist is learned through GAN or Diffusion Models, and then converted into 3D using 3D conversion software and deep learning. And we compare the results with prior algorithms. After that, we will analyze the problems and improvements of 2D to 3D creative generation.

지난호에서는 2012년 가을학기 Harvard GSD의 Digital Media and Material Practice 수업의 일환으로 진행되었던 Diffusion Limited Aggregation System에 대하여 이야기를 시작했습니다. 먼저 유한 확산 집합체가 무엇인지를 자연에서 쉽게 발견할 수 있는 눈 결정의 현미경 사진을 통하여 알아 보았고 이 현상이 어떻게 일어나는 지에 대한 고찰을 통하여 유한 확산 집합체를 디지털 모형으로 생성하기 위한 밑그림을 그려보았습니다. 이번 회에서는 이를 디지털 모형으로 재구성했던 방법을 Visual Basic 을 통하여 단계별로 알아보도록 하겠습니다.

The purpose of this paper is to consider how the Korean major broadcasts employs their broadcasting human resources and makes use of them in connection with broadcasting education as media education in universities. The problems deals with broadcasting education in universities, particularly with regard to the point of broadcasts view, with the training & reeducation systems and with the academic-industrial cooperation. By using depth interview with experts(directors of personnel management of the broadcasts), this paper explores meaning of media education for the training of broadcasting human resources. In the opinions of the responsible officers for personnel management, it distinctly exists different points of view between the related academic circle and the broadcasting on-site. The related academic circle criticizes the chronic invariability of broadcasts, and the broadcasts the impractical broadcasting education of the academic circle.

To overcome the weakness of the image retrieval system using the existing Ontology and the distributed image based on the database having a simple structure, HERMES was suggested to ensure the self-control of various image suppliers and support the image retrieval based on semantic, the mentioned framework could not solve the problems which are not considered the deterioration in the capacity and scalability when many users connect to broker server simultaneously. In this paper the tables are written which in the case numerous users connect at the same time to the supply analogous level of services without the deterioration in the capacity installs Broker servers and then measures the performance time of each inner Broker Component through Monitoring System and saved and decides the ranking in saved data. As many Query performances are dispersed into several Servers User inputted from the users Interface with reference to Broker Ranking Table, Load Balancing system improving reliability in capacity is proposed. Through the experiment, the scheduling technique has proved that this schedule is faster than existing techniques.

In this paper, an investigation of weapon tracking performance is shown in regard to improving individual weapon performance of aiming objects. On the battlefield, a battle can last only a few hours, sometimes it can last several days until finished. In these long-lasting combats, a wide variety of factors will gradually lower the visual ability of soldiers. The experiments were focusing on enhancing the degraded aiming performance by applying visual tracking technology to roof mounted sights so as to track the movement of troops automatically. In order to select the optimal algorithm among the latest visual tracking techniques, performance of each algorithm was evaluated using the real combat images with characteristics of overlapping problems, camera's mobility, size changes, low contrast images, and illumination changes. The results show that VTD (Visual Tracking Decomposition)[2], IVT (Incremental learning for robust Visual Tracking)[7], and MIL (Multiple Instance Learning)[1] perform the best at accuracy, response speed, and total performance, respectively. The evaluation suggests that the roof mounted sights equipped with visual tracking technology are likely to improve the reduced aiming ability of forces.
