This study is concerned with an assistive technology which reduces color blinds´s confusion when they access electronic documents including color objects in their computers. In this study, 1 restrict the assistive technology would apply to windows operating system, 256 color mode and implement to minimize color distortion which occurs in multi window environments because of color approximation process. As a basic palette, I use a 216 colors web safe palette which the Christine proposed as a standard for color blind, expand it to 256 colors to apply all computer displays using Microsoft Windows as its operating system and implement it as windows application. To test its effectiveness, I use a simulator for dichromats, as results of the test, the developed color vision deficiency correction S/W is effective to reduce the confusion. It is more effective to use the implemented S/W in both of design and client process for electronic documents.

The French neo-impressionist painter, George Seurat, introduced pointillism under the theory that the individual pigments of colors on the canvas are reconstructed on the human retina. Pointillism is a painting technique in which many small brush strokes are combined to form a picture in the canvas. When such a painting is seen from a far, the individual stroke color are unnoticeable and they are seen as intermixed colors. This is called juxtaposed color mixture. In this paper, we present a painterly rendering method for generating the pointillism images. For expressing countless separate dots which shown in the pointillism works, we propose a hierarchical points structure using Wang The method. Also a user defined palette is constructed based on the usage that Neo-Impressionist painter works on his palette. Lastly, based on this, a probability algorithm will be introduced, which divides the colors in the image(sampled by hierarchical point structure) into juxtaposed colors. A hierarchical points set which undergone juxtaposed color division algorithm is converted into brush strokes.

To produce deep, entertaining mobile content, a large number of images must be included. But because of the limits on runtime memory for mobile phones, images cannot be used as easily in a mobile environment as they are in a computer. Therefore in this paper, I propose several different methods for efficiently using images in a mobile environment. The various methods I propose for using images are: Creating images using compression/decompression and rotation/symmetry Creating images of several different colors by changing the palette index of a bitmap Creating images through image combination Creating background images by using tile maps Creating new images through effects.

In this paper, we present a non-static color histogram method to retrieve clothing images that are similar to a query clothing. Given clothing area, our method automatically extracts major colors by using the octree-based quantization approach[16]. Then, a color palette that is composed of the major colors is generated. The feature of each clothing, which can be either a query or a database clothing image, is represented as a color histogram based on its color palette. We define the match color bins between two possibly different color palettes, and unify the color palettes by merging or deleting some color bins if necessary. The similarity between two histograms is measured by using the weighted Euclidean distance between the match color bins, where the weight is derived from the frequency of each bin. We compare our method with previous histogram matching methods through experiments. Compared to HSV cumulative histogram-based approach, our method improves the retrieval precision by 13.7 % with less number of color bins.

For the students who specialize in interior design irrespective of their color susceptibility, it is prerequisite to precede a systematic curriculum in the first place on how to put the color theory to practical use. Therefore, this curriculum has its purpose to let the students study on how to put to practical use of their understanding of color as one of the finishing materials for interior design. The 16-weekschool days has been segmented into a theoretical study and practical training, This thesis has summed up the basic instance of the color theory, the first of the three basicpractical courses and presented its results to the students. In due course of this curriculum, the students were recommended to pick up one photo image of their selection out of which they could make out color palette based on their analysis of the photo image, so that they could study on how to apply their color palette to a three dimensional space. Firstly, through this course, they could experience the process for a color image that they had so far sensed subjectively and vaguely to become an objective inevitable result. Secondly, they studied on the process of how a two-dimensionalcolor image could be applied for a three-dimensional space. It is significant of this curriculum in the sense that the students become prepared through this study course with essential knowledge applicable to various interior designs in their future.

제품의 LIFE CYCLE이 짧아지고 있는 추세에 이미 출시된 제품에서 칼라 변경만을 통해 신제품과 같은 효과를 볼 수 있는데 칼라변경은 기능추가나 금형 수정에 비해 상대적으로 비용이 적게 들어가기 때문에 그 효용성은 더욱 크다고 할 수 있다. 본 연구는 현재 판매되고 있는 A사의 가습기를 Trend 분석을 통해 칼라와 그래픽 요소의 변경만으로 신 제품화하여 가습기 칼라 변경에 대한 경쟁력을 높이기 위한 디자인 사례연구이다.

대부분의 컬러 영상들은 코드북의 일부분만으로 표현할 수 있는 영상의 영역이 상당히 크므로 이러한 특징을 이용하는 효율적인 Reversible 워터마킹 기법을 제안한다. 팔레트(컬러맵) 영상에서의 워터마킹 기술에 대한 연구는 많이 있지만 Reversibility에 대한 관심은 상대적으로 낮았다. 제안하는 기법은 가상적으로 확장한 코드북에 의한 압축 영역에서 동작한다. 확장된 코드북은 높은 Payload 용량을 가진다. Reversibility를 구현하면서 왜곡(Distortion)과 삽입용량(Embedding capacity)사이의 절충점을 실험을 통해 보인다.

본 논문에서는 한국어 입력 텍스트의 의미를 반영하는 색상 팔레트를 생성하는 방법을 제안한다. 기존 영문 모델에서 한국어의 특수성을 고려하여 입력 방법과 형태소 분석, 임베딩 등 여러 조건을 달리한 접근을 시도하고 최종적으로 두개의 모델을 선정하여 평가를 진행한다. 정량적 평가인 단일 팔레트 다양성 평가와 정성적 평가인 사용자 평가를 진행하였으며 결과 기존 영문 버전보다 다양성이 높았고 사용자가 실제 팔레트 보다 생성된 팔레트를 선호하는 비율도 향상되었다. 이번 연구로 한국어 임베딩을 활용하여 팔레트를 생성하였을 때 보다 다양한 색상과 의미적으로도 적합한 색상을 선정함을 확인할 수 있었다.

It is safe to say that color is among the most important elements in design. Thus, most designers give much thought about color while finishing their works. However, it is not easy to use the color interface of computer graphics programs, which makes it difficult for designers to apply the color theory and color scheme theory they've learned at school into the real design works. In fact, the same color systems as those of Adobe's first version of Photoshop or other illustration programs are still being used. Despite the advancement of digital equipment and development of printing technology, color palettes haven't changed accordingly, making it difficult to find a proper color coordination. Based on surveys and color scheme theories and taking designers' convenience into consideration, I will suggest in this paper a new color interface with which the color system and color scheme theories can be easily applied. However, its use in reality is not dealth with in this paper since it requires more practical discussions and studies.
