The purpose of this study was to investigate the relationship between Chanel design and her Costume jewelry in 1920's-1930's through documentary studies. According to the study the result was as follows: 1. Chanel's esthetic in the field of Fashion Design bore the double stamp of "elegance" and 'simplicity' 2. Chanel changed the concept of costume jewelry. Chanel's great innovation was that she let 'fake' jewels always keep the intrinsic value of 'real' ones. 3. The simplicity of her perfectly tailored suit was Paradoxically overwhelmed by a fan-tastic array of jewels. The relationhship be-tween Chanel design and her costume jewelry was not able to be seperated. Chanel was a fashion leader fifty years ago and the name "Chanel" will be at the forefornt of fashon fifty years from now. The image of quality will always remain the same in the futures.

This paper aims to give a quick view on denoising without comprehensive details. Denoising can be understood as removing unwanted parts in signals and images. Noise incorporates intrinsic random fluctuations in the data. Since noise is ubiquitous, denoising methods and models are diverse. Starting from what noise means, we briefly discuss a denoising model as maximum a posteriori estimation and relate it with a variational form or energy model. After that we present a few major branches in image and signal processing; filtering, shrinkage or thresholding, regularization and data adapted methods, although it may not be a general way of classifying denoising methods.

The repeatability of fabric drape was studied. Two methods for draping were used and the relation between node distributions was investigated using statistical analysis. With this, the relationship between node distribution and fabric mechanical properties was studied. The repeated measurements showed that there was no evidence that fabric has intrinsic node number and the mechanical properties influence on the number of nodes.

We present a GUI-based interactive Python program, VIMAP, which generates radio spectral index maps of active galactic nuclei (AGN) from Very Long Baseline Interferometry (VLBI) maps obtained at different frequencies. VIMAP is a handy tool for the spectral analysis of synchrotron emission from AGN jets, specifically of spectral index distributions, turn-over frequencies, and core-shifts. In general, the required accurate image alignment is difficult to achieve because of a loss of absolute spatial coordinate information during VLBI data reduction (self-calibration) and/or intrinsic variations of source structure as function of frequency. These issues are overcome by VIMAP which in turn is based on the two-dimensional cross-correlation algorithm of Croke & Gabuzda (2008). In this paper, we briefly review the problem of aligning VLBI AGN maps, describe the workflow of VIMAP, and present an analysis of archival VLBI maps of the active nucleus 3C 120.

Among the diverse apartment brand TV Ads, KCC Switzen uses a unique advertising strategy. Unlike their competitors, KCC Switzen uses a strategy without fancy rhetoric such as luxury, premium or high-tech to enhance the value of their housing. In order to define the value of contemporary housing this paper analyses the socio-cultural messaging of KCC Switzen's television advertisements using Qualitative content analysis and Floch's Semiotic Square of Consumption Values method. As a result of this analysis, KCC Switzen's advertisements are shown to contain both intrinsic values of housing and cultural humanism by asking ablout the daily lives of real families and their relationships with neighbors. This directly contrasts with the standard advertisements that focus on the investment value of residential housing. The unique KCC Switzen advertising strategies are expected to change the paradigm of residential housing.

Digital media technology is gradually developing with the development of convergence quaternary industrial technology and mobile devices. The combination of deep learning and augmented reality can provide more convenient and lively services through the interaction of 3D virtual images with the real world. We combine deep learning-based pose prediction with augmented reality technology. We predict the eight vertices of the bounding box of the object in the image. Using the predicted eight vertices(x,y), eight vertices(x,y,z) of 3D mesh, and the intrinsic parameter of the smartphone camera, we compute the external parameters of the camera through the PnP algorithm. We calculate the distance to the object and the degree of rotation of the object using the external parameter and apply to AR content. Our method provides services in a web environment, making it highly accessible to users and easy to maintain the system. As we provide augmented reality services using consumers' smartphone cameras, we can apply them to various business fields.

The sensor system to measure the distance precisely from the center of the sensor system to the obstacle is needed to recognize the surrounding environments, and the sensor system is to be calibrated thoroughly to get the range information exactly. This study covers the calibration of the active range sensor which consists of camera and laser slit emitting device, and provides the equations to get the 3D range data. This can be possible by obtaining the extrinsic parameters of laser slit emitting device through image processing the slits measured during the constant distance intervals and the intrinsic parameters from the calibration of camera. The 3D range data equation derived from the simple geometric assumptions is proved to be applicable to the general cases using the calibration parameters. Also the exact 3D range data were obtained to the object from the real experiment.

Our study explores the connection between the Pythagorean theorem and the Fixed-point theorem in metric spaces. Both of which center around the concepts of distance transformations and point relationships. The Pythagorean theorem deals with right triangles in Euclidean space, emphasizing distances between points. In contrast, fixed-point theorems pertain to the points that remain unchanged under specific transformations thereby preserving distances. The article delves into the intrinsic correlation between these concepts and presents a novel study in Euclidean metric spaces, examining the relationship between contraction mapping and Pythagorean Right Triangles. Practical applications are also discussed particularly in the context of image compression. Here, the integration of the Pythagorean right triangle paradigm with contraction mappings results in efficient data representation and the preservation of visual data relation-ships. This illustrates the practical utility of seemingly abstract theories in addressing real-world challenges.

전자기록물은 그 특성상 휘발성과 불안정성이 높으며, 이를 장기간 이용할 수 있도록 유지하는 것은 중요하다. 국가기록원은 이를 위해 전자기록물 보존포맷 선정체계를 수립하였으나, 현재 보존포맷 선정체계는 문서 유형의 전자기록물만을 그 범위로 하고 있어 시청각기록물 등 다른 유형의 기록물에 적용하기에 적합하지 않다. 본 논문은 이미지 유형 전자기록물을 중심으로 기존 체계의 적용 범위 확장과 이미지 유형 전자기록물의 보존에 대한 기초적인 가이드라인 구축을 목적으로 한다. 국내에서 이미지 유형 전자기록물은 문서 유형 전자기록물 다음으로 가장 많은 수량을 가진 유형이다. 이미지 유형은 시청각기록물의 가장 기본적인 형태로, 이에 대한 연구는 향후 다른 시청각기록물에 관한 논의의 기반을 마련한다. 이에 본 연구는 이미지 유형 전자기록물에 대한 보존포맷 선정체계를 구축하였다. 이를 통해 향후 새로운 이미지 포맷의 등장에도 해당 체계를 활용하여 보존포맷의 적합성을 신속하고 효율적으로 평가할 수 있다. 이를 검증하기 위해 연구에서 제안된 보존포맷 선정체계를 실제 이미지 포맷에 적용하여 평가를 진행하였으며, 그 결과로 TIFF, JFIF, PNG 포맷이 보존포맷으로 선정되었다. 이러한 결과는 향후 포맷 평가의 실질적인 참고 자료로써 활용될 수 있다.

본 논문에서는 광각 카메라로 촬영한 영상에서 생기는 영상의 왜곡 문제를 해결하기 위하여, 카메라 모델의 추정과 검증을 통하여 광각 카메라 영상에서의 방사형 왜곡을 보정하는 방법을 제안한다. 먼저, 교정 패턴으로부터 렌즈의 초점 거리와 주점의 위치 등으로 구성된 내부 파라미터와 회전과 위치 정보로 구성된 외부 파라미터를 찾음으로써 카메라의 왜곡 모델을 추정한다. 다음으로, 추정된 카메라 모델로부터 역으로 코너점을 다시 추출하여 검증하고, 마지막으로, 검증된 카메라 모델을 이용하여 영상의 왜곡을 보정한다. 일반 웹 카메라와 광각 카메라로부터 격자 모양의 교정 패턴을 촬영한 영상을 이용하여 방사형 왜곡을 보정하는 실험을 수행한 결과, 제안된 방법이 80% 이상의 개선 성능을 보임을 확인하였다.
