In this paper, the purpose is to create a standard of AI training dataset type for commercial space design. As the market size of the field of space design continues to increase and the time spent increases indoors after COVID-19, interest in space is expanding throughout society. In addition, more and more consumers are getting used to the digital environment. Therefore, If you identify trends and preemptively propose the atmosphere and specifications that customers require quickly and easily, you can increase customer trust and conduct effective sales. As for the data set type, commercial districts were divided into a total of 8 categories, and images that could be processed were derived by refining 4,009,30MB JPG format images collected through web crawling. Then, by performing bounding and labeling operations, we developed a 'Dataset for AI Training' of 3,356 commercial space image data in CSV format with a size of 2.08MB. Through this study, elements of spatial images such as place type, space classification, and furniture can be extracted and used when developing AI algorithms, and it is expected that images requested by clients can be easily and quickly collected through spatial image input information.

디지털 기술의 급속한 발전에 힘입어 사용자에게 유용한 디지털 영상들이 지수적으로 증가함에 따라, 내용 기반 영상 검색(CBIR ; Content-based Image Retrieval)은 가장 활발한 연구 분야 중 하나가 되었다 다양한 영상 검색 방법은 입력 질의 영상이 주어졌을 때, 질의와 유사한 영상들이 칼라(color)나 질감(texture) 같은 저 수준 특징을 기반으로 영상 데이터베이스에서 검색되도록 제안되어져 왔다. 그러나, 기존 검색 방법의 대부분은 부분 정합에 필요한 복잡도(complexity) 때문에 데이터베이스 내 전체 영상의 부분 영상을 입력 질의 영상으로 했을 경우를 고려하지 않았다. 이 논문에서 우리는 두 영상 사이의 칼라 히스토그램 관계를 이용함으로써 부분 영상 정합에 대한 효율적인 방법을 제시한다. 제안된 접근 방법은 두 단계로 구성되어 있다. 첫 번째 단계는 검색 공간을 pruning시키는 것이고 두 번째 단계는 부분 영상 정합을 통해 후보 영상들의 순위를 정하는 블록 기반 검색을 수행한다. 실험 결과는 pruning없이 부분 영상 정합만 사용하여 검색했을 때 시스템의 응답 시간이 높다고 가정을 하고 제안된 알고리즘의 실현 가능성을 보여준다.

This research deals with a problem of reconstructing 3D surface structures from their 2D projections, which is an important research topic in computer vision. In order to provide robust reconstruction algorithm, that is reliable even in the presence of uncertainty in the range images, we first present a detailed model and analysis of several error sources and their effects on measuring three-dimensional surface properties using the space encoded range imaging technique. Our approach has two key elements. The first is the error modeling for the space encoding range sensor and its propagation to the 3D surface reconstruction problem. The second key element in our approach is the algorithm for removing outliers in the range image. Such analyses, to our knowledge, have never attempted before. Experimental results show that our approach is significantly reliable.

The latest university makes the use of exhibition hall bring into relief a specific character and identity. This purpose of this design is to induce interest the exhibition plan, that is useful to appreciation of audience according to space structure. The concept of this design is to design continual circulation plan and to give correctness Information of the exhibit. Because to this exhibition hall is too small space, this design focus is continual circulation plan. The exhibit is classified to according to the character of that, which is distinguished according to the colour plan. The center of the hall is main image hall of university. The right space of the main hail is university history exhibition hall and the left space of the hall is a founder memorial hall. The main colour is light cream. An image object colour plan is point colou, which is bluish green colour.

The solution way of color difference in display device is using a device profile recorded with color dimension, color properties of each device and is using sRGB color space. The color matching is better sRGB than RGB color space. The sRGB is independent device color space and based on the monitor characteristice. An accurate characterization of the display device is essential for color matching. The calibration and characterization process in display device is needed to transform the device dependent color to the device independent color. The process of characterization performs a linerizaiton and transforms the linearized values into the CIE XYZ tristimulus values. The purposes of this paper is to estimate color reproduction using device profile and to explain the propriety of transformation method using variable.

The Intelligent Space(ISpace) provides challenging research fields for surveillance, human-computer interfacing, networked camera conferencing, industrial monitoring or service and training applications. ISpace is the space where many intelligent devices, such as computers and sensors, are distributed. According to the cooperation of many intelligent devices, the environment, it is very important that the system knows the location information to offer the useful services. In order to achieve these goals, we present a method for representing, tracking and human following by fusing distributed multiple vision systems in ISpace, with application to pedestrian tracking in a crowd. And the article presents the integration of color distributions into particle filtering. Particle filters provide a robust tracking framework under ambiguity conditions. We propose to track the moving objects by generating hypotheses not in the image plan but on the top-view reconstruction of the scene. Comparative results on real video sequences show the advantage of our method for multi-object tracking. Also, the method is applied to the intelligent environment and its performance is verified by the experiments.

While hyperspectral data are very rich in information, their processing poses several challenges such as computational requirements, noise removal and relevant information extraction. In this paper, the application of advanced scale-space filtering to selected hyperspectral bands was investigated. In particular, a pre-processing tool, consisting of anisotropic diffusion and morphological leveling filtering, has been developed, aiming to an edge-preserving smoothing and simplification of hyperspectral data, procedures which are of fundamental importance during feature extraction and object detection. Two scale space parameters define the extent of image smoothing (anisotropic diffusion iterations) and image simplification (scale of morphological levelings). Experimental results demonstrated the effectiveness of the developed scale space filtering for the enhancement and smoothing of hyperspectral remote sensing data and their advantage against watershed over-segmentation problems and edge detection.

Spaceborne cryocoolers produce undesirable micro-vibration disturbances during their on-orbit operation, which are a primary source of image-quality degradation for high-resolution observation satellites. Therefore, to comply with the strict mission requirement of high-quality image acquisition, micro-vibration disturbances induced by cooler operation have always been subjected to an isolation objective. However, in this study, we focused on the applicability of energy harvesting technology to generate electrical energy from micro-vibration energy of the cooler and investigated the feasibility of utilizing harvested energy as a power source to operate low-power-consumption devices such as micro-electromechanical system (MEMS) devices. A tuned mass damper (TMD)-type electromagnetic energy harvester combined with a conventional passive vibration isolator was proposed to achieve this objective. The system performs the dual functions of electrical energy generation and micro-vibration isolation. The effectiveness of the strategy was evaluated through numerical simulations.
