  • This paper presents a method of object classification from dynamic image based on fuzzy inference algorithm which is suitable for low speed such as, conveyor, uninhabited transportation. At first, by using feature parameters of moving object, fuzzy if - then rule that can be able to adapt the wide variety of surroundings is developed. Secondly, implication function for fuzzy inference are compared with respect the proposed algorithm. Simulation results are presented to testify the performance and applicability of the proposed system.

  • In this paper, we analyze the delay phenomenon that can occur when controlling an unmanned aerial vehicle using a camera and describe a solution to solve the phenomenon. The group of pictures (GOP) value is changed in order to reduce the delay according to the frame data size that can occur in the moving image data transmission. The appropriate GOP values were determined through experimental data accumulation and validated through camera self-test, system integration laboratory (SIL) verification test and system integration test.

  • Among the compression methods of moving picture information, a motion estimation method is used to remove time-repeating. The Block Matching Algorithm in motion estimation methods is the commonest one. In recent days, it is required the more advanced high quality in many image processing fields, for example HDTV, etc. Therefore, we have to accomplish not by means of Partial Search Algorithm, but by means of Full Search Algorithm in Block Matching Algorithm. In this paper, it is suggested a structure that reduce total calculation quantity and size, because the structure using Bit Plane select and use only 3bit of 8bit luminance signal.

  • Since Cubists represented a way of expressing image moving away from traditional illusion effect, new realities represented by collage and assemblage. Furthermore, Marcel Duchamp, a French Dadaist, suggested the concept of ready-made that everyday objects exhibited in an odd way in a gallery. These early fine art cases highly influenced to furniture design in the second half of the twentieth century. The use of objects in contemporary furniture is closely related to the emergence of Pop Art in the late 1950s and that of Postmodernism. After the 1970s the use of found objects were frequently utilized in furniture design of all over the countries. As an ecological issue became a new consideration to furniture designers, found objects also gave a chance to use recycled materials. Even in studio furniture area which is considered wood as a major material at the early stage, many studio furniture designers began to adapt found objects in their designs as a new source of Inspiration after the 1970s. This study explored various examples of found objects in furniture design and examined the meaning of the use in different designers and regions.

  • 수많은 CCTV에서 기록 보관되는 영상 데이터가 폭발적으로 증가하면서, 빅데이터 환경에 적합한 CCTV 영상 데이터의 처리와 응용이 큰 이슈가 되고 있다. 본 논문에서는 대규모 CCTV 영상 데이터를 하둡 기반으로 병렬처리하고, 이를 활용한 VRT(Vehicle Route Tracking) 시스템을 설계 구현한다. VRT 시스템은 대규모 차량 번호판 인식 시스템의 특성을 가지며, 구글 맵을 통해 특정 차량의 이동경로를 빠른 시간 내에 추적 가능케 한다. 그리고 VRT 시스템의 성능 평가를 위한 실험을 통하여 단일 PC와 하둡 환경에서 대규모 CCTV 영상 데이터의 번호판 인식 시간을 비교 분석한다.

  • It is very important to share tactical information such as video, images, and text messages among soldiers for situational awareness. Under the wireless environment of the battlefield, the available bandwidth varies dynamically and is insufficient to transmit high quality images, so it is necessary to minimize the distortion of the area of interests such as targets. A natural operating method for soldiers is also required considering the difficulty in handling while moving. In this paper, we propose a natural ROI(region of interest) setting and image compression method for effective image sharing among soldiers. We verify the proposed method through prototype system design and implementation of eye gaze detection and ROI-based image compression.

  • In general, the swing motion of the crane is controlled and suppressed by activating the trolley motion. In many papers reported by us, we suggested a new type of anti-sway control system of the crane. In the proposed control system, a small auxiliary mass(moving-mass) is installed on the spreader and the swing motion is controlled by moving the auxiliary mass. The actuator reaction against the auxiliary mass applies inertial control forces to the container in order to reduce the swing motion in the desired manner. Futhermore the measuring systems based on image sensor have been proposed also. To obtain the robustness for our control system, $H_{\infty}$ based control techniques and other approach have been applied to suppress swing motion. As well known, the robust control technologies based on $H_{\infty}$ control need complicated and difficult process. In the result, the obtained closed-loop system becomes to high order system which may give us many difficulties to apply it to the real plants. Therefore, we introduce an easy approach which is based on LQ control theory. In this approach, we introduce the frequency dependent weighting matrices which give the system filters to shape frequency characteristics of the controlled system and guarantee the control performance.

  • 관람객 자신이 보고 있는 영상 콘텐츠의 공간속에 있는 느낌이나 심리적 경험을 프레즌스라고 한다. 본 논문에서는 (1) 어떤 영상 이미지와 형태에 따라 향상 또는 증강되는지, (2) 관람자의 개개인의 특성에 따른 프레즌스의 변화, (3) 인터랙티브가 가미된 영상작품에서 인터랙티비티가 프레즌스 향상에 어떠한 영향을 미치는지에 대하여 분석하고자 한다. 실험영상으로는 본인이 제작한 "The Light"를 사용하였다. 본 연구에서는 실험영상을 대상으로 연구를 진행하였으며, 실험영상의 주요한 시각적 구성요소인 색상과 형태를 분류하여 프레즌스를 측정하였다. 실험을 통하여 실험영상에 인터랙티브가 가미된 영상을 제작하는 것이 본인의 작품에 프레즌스를 높인다는 결과를 얻었다. 실험영상과 인터랙티브가 가미된 영상의 프레즌스를 측정하기 위해 기존 프레즌스 측정연구를 토대로 새로운 설문지를 작성하였으며, 측정도구로는 설문지 조사형태인 PQS와 뇌파측정 방법인 EEG 측정을 결합하여 실험하였다. 실험 결과에서, 뇌파 측정에 따른 알파파와 베타파의 변화는 프레즌스 증감에 따라 결과치가 달라짐을 확인하였다.

  • We present the design and implementation of a unique sensing and actuation application -- the Illuminator: a sensor network-based intelligent light control system for entertainment and media production. Unlike most sensor network applications, which focus on sensing alone, a distinctive aspect of the Illuminator is that it closes the loop from light sensing to lighting control. We describe the Illuminator's design requirements, system architecture, algorithms, implementation and experimental results. The system uses the Illumimote, a multi-modal and high fidelity light sensor module well-suited for wireless sensor networks, to satisfy the high-performance light sensing requirements of entertainment and media production applications. The Illuminator system is a toolset to characterize the illumination profile of a deployed set of fixed position lights, generate desired lighting effects for moving targets (actors, scenic elements, etc.) based on user constraints expressed in a formal language, and to assist in the set up of lights to achieve the same illumination profile in multiple venues. After characterizing deployed lights, the Illuminator computes optimal light settings at run-time to achieve a user-specified actuation profile, using an optimization framework based on a genetic algorithm. Uniquely, it can use deployed sensors to incorporate changing ambient lighting conditions and moving targets into actuation. Experimental results demonstrate that the Illuminator handles various high-level user requirements and generates an optimal light actuation profile. These results suggest that the Illuminator system supports entertainment and media production applications.

  • Detecting of the object in image processing is substantial but it depends on the object itself and the environment. An object can be detected either by its shape or color. Color is an essential for pattern recognition and computer vision. It is an attractive feature because of its simplicity and its robustness to scale changes and to detect the positions of the object. Generally, color of an object depends on its characteristics of the perceiving eye and brain. Physically, objects can be said to have color because of the light leaving their surfaces. Here, we conducted experiment in the aquarium fish tank. Different color of fish robots are mimic the natural swim of fish. Unfortunately, in the underwater medium, the colors are modified by attenuation and difficult to identify the color for moving objects. We consider the fish motion as a moving object and coordinates are found at every instinct of the aquarium to detect the position of the fish robot using OpenCV color detection. In this paper, we proposed to identify the position of the fish robot by their color and use the position data to control the fish robot gathering in one point in the fish tank through serial communication using RF module. It was verified by the performance test of detecting the position of the fish robot.
