This paper presents the design and implementation of virtual aquarium by generating 3D models of fishes that are colored by viewers in an aim to create interaction among viewers and aquarium. The virtual aquarium system is composed of multiple texture extraction modules, a single interface module and a single display module. The texture extraction module recognize the QR code on the canvas to get information of the predefined mapping table and then extract the texture data for the corresponding 3D model. The scanned image is segmented and warp transformed onto the texture image by using the mapping information. The extracted texture is transferred to the interface module to save on the server computer and the interface module sends the fish code and texture information to the display module. The display module generates a fish on the virtual aquarium by using predefined 3D model with the transmitted texture. The fishes on the virtual aquarium have three different swimming methods: self-swimming, autonomous swimming, and leader-following swimming. The three different swimming methods are discussed in this paper. The future study will be the implementation of virtual aquarium based on storytelling to further increase interactions with the viewer.

이 논문에서는 각기 다른 스케일에서 각각의 구조를 띤 텍스처를 합성하는 기법을 제안한다. 우리의 기법은 GPU로 실시간으로 수행되는 병렬 텍스처 합성 기법에 기반을 두었다. 새로 도입된 좌표 변환 연산자를 이용하면 이미 합성된 좌표 맵을 다른 스케일의 입력 텍스처로의 좌표 공간으로 변환할 수 있다. 이 연산자는 작은 룩업 테이블로 미리 연산될 수 있기 때문에 본 기법을 도입함으로써 생기는 오버헤드는 매우 적다. 우리의 업샘플 기법은 텍스처가 두드러전 이미지의 해상도를 높일 때 특히 유용하다. 그리고, 우리의 기법을 이용하여 저해상도 컨트롤 이미지를 이용한 텍스처 디자인도 가능하다. 이 디자인 툴은 지형을 특정한 스타일로 디자인하는 데에 유용하며 일반적인 높낮이 조절 브러시를 이용할 수 있으므로 직관적이다.

Texture mapping is the process of covering 3D models with texture images in order to increase the visual realism of the models. For proper mapping the coordinates of texture images need to coincide with those of the 3D models. When projective images from the camera are used as texture images, the texture image coordinates are defined by a camera calibration method. The texture image coordinates are determined by the relation between the coordinate systems of the camera image and the 3D object. With the projective camera images, the distortion effect caused by the camera lenses should be compensated in order to get accurate texture coordinates. The distortion effect problem has been dealt with iterative methods, where the camera calibration coefficients are computed first without considering the distortion effect and then modified properly. The methods not only cause to change the position of the camera perspective line in the image plane, but also require more control points. In this paper, a new iterative method is suggested for reducing the error by fixing the principal points in the image plane. The method considers the image distortion effect independently and fixes the values of correction coefficients, with which the distortion coefficients can be computed with fewer control points. It is shown that the camera distortion effects are compensated with fewer numbers of control points than the previous methods and the projective texture mapping results in more realistic image.

The purpose of this study was to analyze the effect of the structural properties, the color characteristics and the texture of sight and touch on the tactile preferences for the black fabrics. Male and female university students were asked to evaluate the texture of sight and touch and tactile preference to the nine different black fabrics which were selected on the basis of the previous research results. Data were analyzed by using frequency analysis, mean, factor analysis, t-test, F-test, correlation and regression analysis. The texture of sight and touch for black fabrics was classified into four factors: smoothness, bulkiness, extensibility, firmness. This texture of sight and touch factors showed a significant correlative relationship to the structural properties and color characteristics of the black fabrics. There were significant differences according to black fabrics on the point of texture of sight and touch. The velvet was evaluated the most smooth fabric, while the velvet and fake leather were evaluated the most bulky fabrics. Also, the jersey and lace fabrics were evaluated the most extensible fabrics, while the melton was evaluated as the most firm fabrics. There were significant correlative relationships not only between the structural properties and the texture of sight and touch but also between the color characteristics and the texture for black fabrics. Also, among the structural properties, the color characteristics and the texture of sight and touch of black fabrics, major variable factor of influencing on the tactile preference was turned out to be the texture of sight and touch.

고유의 텍스쳐 성분에만 최적 반응을 하는 최적 필터(optimal filter)는 다중 텍스쳐 영상으로부터 원하는 텍스쳐 성분을 추출하기 위한 가장 뛰어난 기술이다. 그러나 기존의 최적필터 설계 방법들은 영상에 내재된 텍스쳐 정보가 사전에 주어지는 교사적 방법이 대부분이며, 내재된 텍스쳐 인식을 기반으로 하는 완전 비교사적인 방법에 관한 연구는 거의 이루어지고 있지 않은 실정이다. 따라서 본 논문에서는 효율적인 텍스쳐 분석을 위한 비교사 학습 방법과 가버필터의 주파수 대역 통과형 특징을 이용한 새로운 최적 필터 설계 방법을 제안한다. 제안한 방법은 자기조직형 신경회로망에 의해서 영상에 내재된 텍스쳐 영역을 블록 단위로 군화(clustering)하며, 가버필터의 최적 주파수는 인식된 텍스쳐 오브젝트(texture objects)의 공간 주파수를 분석한 최적 주파수에 동조(turning)한다. 그리고 설계된 최적 가버필터의 성능 평가를 위해서는 다양한 형태의 다중 텍스쳐 영상을 생성하여 내재된 텍스쳐 오브젝트를 추출함으로써 성공적인 결과를 보인다.

The relationship between the product design and product image can be defined using human sensibility. If there is a way to grasp the product value or product design that people want most, it could be possible to make and sell user-oriented products. In human sensibility ergonomics, the categories of design factor can be broken into shape and color of the design. Although, the color is the major factor of the design, however, texture were is also an important factor for the shape. In this study, wall-papers that have various shapes of texture were used for the experiment. The purpose of this study was to conduct a sensibility estimation experiment for the product image, and to estimate the parameters of various textures for creating new textures that could be more suitable for human sensibility.

다시마를 Vibrio sp.로 분해하여 제조한 SCD를 modified distance design의 최적 배합 비율에 따라 기능성 국수를 제조하였다. 밀가루의 함량이 증가할수록 다시마 SCD 국수의 texture parameter논 증가하였고, 물의 함량이 증가할수록 texture parameter는 반대로 감소하였으며 SCD의 함량이 증가할수록 texture parameter는 감소 후 증가하였다. 밀가루와 SCD의 함량이 증가할수록, 물의 함량이 감소할수록 L 값과 b 값은 증가하였으며, a 값은 밀가루의 함량이 증가할수록 감소하였고 물의 함량이 증가할수록 감소 후 증가하였다. Constraint coefficient 값의 분석 결과 SCD는 건면과 조리면의 texture parameter와 색도의 L(명도) 및 b(황색도) 값, 물은 a(적색도) 값에 가장 큰 영향을 주었으며, hardness를 제외한 texture parameter와 색도에서 원료간의 상호작용이 있었다. Modified distance design에 의해 결정된 최적 배합비율은 밀가루, 물, SCD의 함량이 각각 63.3, 31, 3.7%이었다. 관능검사 결과 잔해수로 처리한 SCD 국수는 시중제품보다 모든 면에서 점수가 약간 떨어지나, 전해수 미처리 SCD 국수보다는 월등히 높은 점수를 받아 전해수의 처리는 본 SCD 국수의 품질향상에 기여할 것으로 판단된다.

Knit is classified into two such as basic texture and applied one according to knitting principle, and the basic texture of weft knitting consists of single knit. rib knit, purl knit and interlock knit. The basic texture of warp knitting consists of double knit texture, double code knit texture and double vandyke knit texture. Fourteen costumes were produced with eighteen (18) different types and twenty four (24) raw materials, and we were trying to show a wide range of costumes produced with knitting by making two different brands at random and making different designs depending on four seasons. Knitting technique is very important element in that it allows special surface effectiveness and decides the characteristic of knitting materials. Knit designer plays very important roles such as selection of raw thread, deciding knitting technique and type of knitting machine in designing the knit. Therefore, the knit designer requires the ability to utilize the function of knitting machine to the maximum, the effort to acquire the variety of knitting technique, develop the new knitting technique and for the improvement of knitting design.
