At 3-D vision measuring, the camera calibration is necessary to calculate parameters accurately. Camera calibration was developed widely in two categories. One is that establishes reference points in space, and the other is that uses the grid type frame and statistical method. But, the former has difficult to setup reference points and the latter has low accuracy. In this paper we present an algorithm for camera calibration using perspective ratio of the grid type frame with different line widths. The advantage of this algorithm is that it can estimate position, pose and distance between camera and object ...

This study analyzed the montage pattern of e-book in a bid to include e-book in the film language system. To this end, this study targeted three pieces of e-books which reproduced the animation for theater use of Disney Company. This study did research on characteristics of montage in films, and kinds of film vectors, and defined it as 'Montage of Experience' according to media characteristics of e-book. This study deducted the montage pattern of 3 sorts of classification, and 10 sorts of detailed classification by doing research on the analysis object. This study has a significance in that it pioneers a new perspective in e-book research which has been biased towards a functional perspective. Analysis of the point of contact where the existing visual media, and new media meet with each other could be a driving force promoting the growth of the relevant industry, and this study thinks that the analysis of the point of contact is the research which is helpful to working out qualitative improvement of e-book contents.

High-resolution satellite imagery are used in various application field such as generation of DEM, orthophto, and three dimensional city model. To define the relation between image and object space, sensor modelling and generation of the epipolar image is essential processes. As the header information or physical sensor model becomes unavailable for the end users due to the national security or commercial purpose, generation of epipolar images without these information becomes one of important processes. In this study, epipolar geometry is generated and analysed by applying two generalized sensor models; parallel and parallel-perspective model Epipolar equation of the parallel model has linear property which is relatively simple; Epipolar geometry of the parallel-perspective model is non-linear. This linear property enable us to generate epipolar image efficiently.

Picasso and Chanel were the most famous artists of modern art & fashion area in 20th century. It is well known that they have deeply influenced to the current fashion and art. This study is aimed to analyze Channel's works based on the aspects of Picasso's from 1900's to 1930's. There are five common, distinct and formative aspects - flatness, geometry, transparency based on multi-perspective, volume, variety of objects. Their works are based on the simplicity which is expressed by the analyzation, organization, deconstruction influenced by cubism. It is reconfirmed that they gave the general public the new value-functionality-by using the ready-made materials. Nowadays artists model themselves after Picasso and Chanel who made attempt to conversion of ideas, the steady style, the long view, the interchange of other fields and popularization.

본 연구는 수학과목 학습이 부진하고, 특히 함수식과 그래프의 관계에 대한 이해가 부족한 특성화 고등학생들을 대상으로 학생들에게 친숙한 엑셀 프로그램을 사용하여 지도한 효과를 살펴보았다. 엑셀의 식, 표, 그래프를 한 화면에 담을 수 있는 기능과 스크롤바를 이용하여 그래프를 움직이는 기능이 주로 사용되었다. 함수개념을 과정관점과 대상관점으로 나누고, 함수 표상을 표, 식, 그래프로 나누었을 때 학생들이 지도를 통하여 표상 내에서 또는 관점 간 유연한 전환이 일어나는 것을 목표로 지도하였고 긍정적인 효과가 나타났다. 실험은 특성화 고등학교 2학년 학생 5명을 대상으로 5일간 컴퓨터실에서 실시되었다. 학생들에 대한 진단평가를 토대로 중학교 수준의 함수와 그래프를 엑셀을 이용해서 지도하였다. 학생들에게는 엑셀파일이 제공되었고, 학생들은 수업 중에 실제 조작해보고 조작결과를 배포된 활동지에 적고 함께 토론하는 방식으로 수업을 진행하였다.

Due to multidisciplinary characteristic of the Interior Design field, it has developed into complex interdisciplinary field. Therefore Interior Design field has grown and established its major trends dependent upon other related field of study. With this perspective in mind, esthetics on Interior Design has to be treated in similar manner. In modem architects or artists have defined the terminology 'object' theoretical principle where by unable to distinguish between 'object's type' and 'objects', Presently, the term 'object' became a trend word. In order to confront misconception of the idea of 'Objectification', some people definition as reflection of this complex society. In this paper, it will establish a solid groundwork for a discussion on Objectification. The initial approach will deal with Le Corbusier and esthetics, which is the center of argument. By reviewing theoretical background of the related modern art, the paper discusses about the relationship between Le Corbusier and esthetics. Subsequently, the discussion about the criterions necessary to define object is provided. This paper only suggests a methodology of analyzing a trend in Interior Design. The condition to define Objectification in Interior Design, which is a result of the reviewing process on esthetics, can be concluded as 'modeling form(transformation of morphological meaning with change wrought by causing a visual reaction)', 'mixtures and modification of materials(transformation and spontaneity through mixing materials)' and 'elements greatly influence space' of the Interior Design.

Language is the method for communication. Semantician, G. Leech categorized the function of language as informational, expressive, directive, aesthetic and phatic one. Therefore, language can be defined as the social symbol system and the media for communication. Space, also, performs the role of symbol, information and communication. Space can be the media for the communication and the design can be logical construction process by it's arbitrary interpretation. The researcher considered the common points between verbal language and visual language as the tools for the mutual communication, tried to transit them into the 'space' as object language after analyzing 'image of poetry' as meta language, so that the old perspective of space design as function can be renewed as information system of the significant meaning delivery in the context of language's multiplicity, expandibility and changeability.

An object tracking system, which uses an omni-directional camera, is proposed in this work. First, we construct a mapping table, which describes the relationships between image coordinates and omni-directional angles Then, we develop a surveillance system to detect unexpected objects automatically from omni-directional images. Finally, we generate perspective views for detected objects by using the mapping table. Simulation results demonstrate that the proposed algorithm provides efficient performances.

A core technology for implementation of Augmented Reality is to develop a merging algorithm between interesting 3-D objects and real images. In this paper, we present a 3-D object recognition method to decide viewing direction toward the object from camera. This process is the starting point to merge with real image and 3-D objects. Perspective projection between a camera and 3-dimentional objects defines a plane in 3-D space that is from a line in an image and the focal point of the camera. If no errors with perfect 3-D models were introduced in during image feature extraction, then model lines in 3-D space projecting onto this line in the image would exactly lie in this plane. This observa...

A limitation is assumed that In this paper, a generalized method is proposed to extract a period of a motion of on object. To detect a periodic motion, we put restrictions on a stationary camera and on a motion of an object. We ca derive the necessary and sufficient condition that an image sequence consists of the projection of the periodic motion by the affine transformation that is a reasonally good approach to the perspective projection. The difficulty of detecting its periodic motion is to select its have period in sequence and to define its width.
