Appropriation is of considerable significance in a cultural trend of thought, as one of the means of realizing the post-modernism period. With the increasing use of appropriation techniques in modern fashion, it is necessary to study the external performance and internal aesthetic value of appropriation in fashion. In the book of cultural appropriation, American scholar James o young divides into three categories of appropriation in culture, namely: object appropriation, content appropriation, and subject appropriation. Based on James O Young's three types of appropriation techniques summarized in the theory of the cultural appropriation, the purpose of this study is through the appropriation of the poncho of traditional Mexican clothing in modern fashion as an example; analyzing the external appropriation characteristics and internal aesthetic significance of different appropriation type. The results are as follows. First, designers take the Originality in modern fashion by expressing Mexican Poncho's form, color, pattern, and material as it is through object appropriation technique. Second, through the Mexican folk poncho's style, designers used these to show the similarity produced by content appropriation in modern fashion. Third, designers used the poncho's design concept or poncho's culture, blending the theme of the collection, adding different color, pattern or materials such as fur, lace, and wool, and presenting a new image different from folk costumes through creative subject appropriation technique.

This paper describe an interactive video object segmentation tool which can be used to generate MPEG-4 video object planes for multimedia broadcasting and enables content based functionalities. In order to apply these functionalities, each frame of video sequence should be represented in terms of video objects. Semiautomatic segmentation can be thought of as a user-assisted segmentation technique. A user can initially mark objects of interest around the real object boundaries. Then the user-guided and selected objects are continuously separated from the unselected areas though time evolution in the image sequences. We proposed method shows very promising result and this encourages the development of object based video editing system.

본 논문에서는 연속적인 입력화상에서 움직임을 나타내는 객체(Object)를 적은 연산량을 사용하여 추출해 내는 알고리즘을 소개한다. 본 알고리즘은 두 가지 단계로 이루어진다. 첫번째 단계로, 이전의 영상과 현재의 영상을 비교하여 움직임의 변화를 보이는 영역을 찾는다. 이 단계에서는 영상을 비교하여 움직임을 추출하기 위하여 창조영상과 현재의 영상, 그리고 영상의 데이터로서 edge정보를 사용한다. 두 번째 단계에서는, 첫번째 단계에서 움직임으로 판단된 Object mask(변화를 가지는 영역)를 가지고 background 제거 및 Object의 정확한 shape을 만들기 위한 post-processing과정을 가지게 된다. 이 두 단계를 거친 후 입력영상에서 background를 떼어낸 최종적인 Object의 shape정보가 추출되게 된다. 이 알고리즘은 object를 기반으로 부호화함으로써 데이터의 압축률을 극대화 시키는 MPEG-4뿐만 아니라, video database, 무선 통신등과 같은 다양한 범위의 application에 적절하게 사용될 수 있을 것이다.

Indoor localization is one of the basic elements of Location-Based Service, such as indoor navigation, location-based precision marketing, spatial recognition of robotics, augmented reality, and mixed reality. We propose a Voxel Labeling-based visual positioning system using object simultaneous localization and mapping (SLAM). Our method is a method of determining a location through single image 3D cuboid object detection and object SLAM for indoor navigation, then mapping to create an indoor map, addressing it with voxels, and matching with a defined space. First, high-quality cuboids are created from sampling 2D bounding boxes and vanishing points for single image object detection. And after jointly optimizing the poses of cameras, objects, and points, it is a Visual Positioning System (VPS) through matching with the pose information of the object in the voxel database. Our method provided the spatial information needed to the user with improved location accuracy and direction estimation.

The most important reason for increasing web traffic and overloaded web servers is a dramatic growth of web users which leads to a great dissatisfaction of each individual user. For overcoming this situation, studies for an acceleration of web content have been conducted actively. We use web caching technology for reducing the load of the web system and traffic in the network. In this paper, we proposed a new web caching technology with the related web object which based on the unit of web processing and characteristics of the web object. Also we verified the availability of the proposed system with comparison and experiments.,

Video object segmentation is one of the core technologies for content-based real-time MPEG-4 encoding system. For real-time requirement, the segmentation algorithm should be fast and accurate but almost all existing algorithms are computationally intensive and not suitable for real-time applications. The MPEG-4 VM(Verification Model) has provided basic algorithms for MPEG-4 encoding but it has many limitations in practical software development, real-time camera input system and compression efficiency. In this paper, we implemented the preprocessing system for real-time camera input and VOP extraction for content-based video coding and also implemented motion detection to achieve the 180 : 1 compression rate for real-time and high compression MPEG-4 encoding.

This paper explores an image segmentation and representation method using Vector Quantization(VQ) on color and texture for content-based image retrieval system. The basic idea is a transformation from the raw pixel data to a small set of image regions which are coherent in color and texture space. These schemes are used for object-based image retrieval. Features for image retrieval are three color features from HSV color model and five texture features from Gray-level co-occurrence matrices. Once the feature extraction scheme is performed in the image, 8-dimensional feature vectors represent each pixel in the image. VQ algorithm is used to cluster each pixel data into groups. A representative feature table based on the dominant groups is obtained and used to retrieve similar images according to object within the image. The proposed method can retrieve similar images even in the case that the objects are translated, scaled, and rotated.

In this paper, we proposed a content-based image retrieval method using color and object's complexity for indexing of image database. Generally, the retrieval methods using color feature can not sufficiently include the spatial information in the image. So they are reduced retrieval efficiency. Then we combined object's complexity which extracted from chain code and the conventional color feature. As a result, experiments shooed that the proposed method which considers the shape feature improved performance in conducting content-based search.

A control system using fuzzy logic for a large capacity continuous dryer has been developed in order to minimize the damage of rice quality. The system has been verified in the case of 17% of object moisture content. With the initial input moisture contents of 20.46%(wb), 20.96%(wb) and 18.98%(wb), the final moisture contents of 17.99%(wb), 17.6%(wb) and 17.23%(wb) are obtained, respectively. The results show that the system controls the moisture content with the maximum error of 0.99% of the object moisture content.

The media facade technique requires the matching process of the content to the projection target. For this reason, each time the projection target is changed, the matching process of the same content must be performed again at each time. This problem can be solved by analyzing the elevation of the object and automatically performing matching process of the content in real time and projecting the matched content. In this paper, we propose and implement a new algorithm that can obtain the optimized matching content in real time by analyzing the elevation of the object to be projected. The proposed method processes the image matching by using the depth information of the elevation obtained by IR cameras.
