In this paper, we propose a new smoothing method for removing moire patterns using analysis of halftone patterns interference. The proposed method can determine a strength of moire patterns by using gray values of pixels and the size of smoothing mask for moire region is adjusted adaptively according to the strength of moire patterns. Therefore it can remove moire patterns effectively and preserve meaningful high frequencies well, such as edges and textures. The proposed method only refer to predefined lookup table to determine the strength of moire patterns, so it is more efficient than a previous work based on FFT of subblock. It could be applied to field of various multimedia applications that deal with color prints.

In this paper, we proposed a content-based image retrieval algorithm using local binary patterns and HSV color histogram. Images are retrieved using image input in image retrieval system. Many researches are based on global feature distribution such as color, texture and shape. These techniques decrease the retrieval performance in images which contained background the large amount of image. To overcome this drawback, the proposed method extract background fast and emphasize the feature of object by shrinking the background. The proposed method uses HSV color histogram and Local Binary Patterns. We also extract the Local Binary Patterns in quantized Hue domain. Experimental results show that the proposed method 82% precision using Corel 1000 database.

The purpose of this study is to link traditional patterns to modern clothing. Of all the traditional patterns, the cloud pattern was chosen for use during the development of a modern one-piece dress design. This study is based upon document searches, including research papers. Through these searches, it investigates the symbolic meaning, historical change, and formation of the cloud pattern. Based on this investigation, the study attempts to modernize the cloud pattern and apply the modernized patterns to the design of a one-piece dress. The design procedure includes three sub-processes: selection, arrangement, and color-scheme. The selection process was divided in two: first, the original form of the cloud pattern was hand-drawn using tracing paper: second, the form of the pattern was edited using Adobe Photoshop. The arrangement of the pattern was made through the checklist conception method, containing the following functions: expand, reset, repeat, and overlap. For the color-scheme of the pattern, Roy Lichtenstein's(1923~1997) work was selected, and the colors in his work were adopted when dyeing the rest of the one-piece dress as well as the cloud features. In conclusion, six modern designs of the one-piece dress were created by using one of Korea's traditional patterns - the cloud pattern. Therefore, this study can offer invaluable suggestions for multifaceted research on how to come up with design concepts which apply Korea's traditional patterns to clothing design.

The evolution of intricate and striking patterns of suspended sediments (SS), which are created by certain physical dynamics in the East China and Yellow Seas, has been investigated using satellite ocean color imageries and vertical profiles of particle attenuation and backscattering coefficients. The structure of these patterns can reveal a great deal about the process underlying their formation. Sea surface temperature (SST) analyzed from the Advanced Very High Resolution Radiometer (AVHRR) thermal infrared data were used to elucidate the physical factors responsible for the evolution of suspended sediment patterns in the East China Sea. The concomitant patterns of suspended sediments were tracked from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) ocean color data. The detailed examination about these patterns gave birth to the definition of the evolution of suspended sediments (SS) into four stages: (1) Youth or Infant stage, (2) Younger stage, (3) Mature stage, and (4) Old stage. We describe about the three directional forces of the tidal currents, ocean warm currents and estuarine circulations that lead to occurrence of various stages of the evolution of suspended sediments that increase turbidity at high levels through out the water column of the inner and outer shelf areas during September to April. The occurrence of these four stages could be repeatedly observed. In contrast, vertical profiles of the particle attenuation ($c_{p}$) and backscattering ($b_{bp}$) coefficients displayed obvious patterns of the propagation of suspended sediment plume from the southwestern coastal sea that leads to eventual collision with the massive sediment plume originating from the Yangtze banks of the East China Sea.

This research was designed to study the Korean dress design trends and different kinds of ancient patterns applied to the Korean dresses in 2001. The trend sources were collected by the HANBOK monthly journal and the symbolism of patterns associated with these patterns being used the prevalent Korean dress collection in markets. The results of the research can be summarized as following; The most of Korean dress image was elegant of ancient mode. Main colors of the traditional Korean jacket were white, yellowish white and green. However, main color of the traditional Korean skirt was represented as red. A plant pattern was the most popular pattern in a practical purpose. It looks beautiful and it is also easily manufactured with open space. Copying other patterns definitely damage the elegance of the Korean dress. It is time for us to not only keep our own traditions but also study and develop new patterns. Designers must study to develop the image and patterns which are agreed with consumer's taste.

The significant role of colors in fashion design is not enough to emphasize in terms of one of the important design elements and its influences on the behaviors of the people. The purpose of this research is to examine the traditional Chinese colors and its ways of color combinations to appreciate the Chinese culture and its people. The Chinese traditional costume of Ching Dynasty were investigated through historic records, historic nobles, costume accessories and so on. The results of the study were summarized as follows： (1) The Blue was the most favoured color for clothing among men and women during Ching dynasty and various blues in terms of hue, value and intensities were used. (2) The bright Yellow which had been a symbol of Emperor were prohibited being used among people. Though, the late period of Dynasty, the regulation became not to strict and various shades of yellow families were adapted among People. (3) The Red which had been preferred during Ming Dynasty were constantly favoured for the formal wears of auspicious events such as weddings. (4) Dark color groups were loved for the clothing which were used as a ground colors against the flamboyant patterns revealing strong visual effects through value contrast or primary color combinations. (5) The White had a symbol of mourning and there were some intentions to adopt pale color groups such as mint, jade, gray, moon whit,. silver white to make up for white. (6) Contrast color combinations were one of the basic ways of color combination in Chinese traditional costume. Therefore Chinese color combinations has a strong visual effect and easy to draw attention of people by the contrast of the hue, value or intensity of color. (7) Multi-color combinations were another characteristics of Chinese costume in the formal wears which bears many surface designs. The surface decorated with full of motifs, were appreciated by the people expressing their longings and hopes through the auspicious meanings of patterns and striking visual effects of color combinations.

Elytra of Harmonia axyridis exhibit varied color patterns. In the present study, we deciphered the genetic basis for intraspecific diversity of elytra color patterns in H. axyridis, using amplified fragment length polymorphism (AFLP). Twenty-eight AFLP reactions were performed to generate a total of 2,741 bands. Of these, 20 bands were polymorphic for each color pattern. The polymorphic bands showed differences of genetic character among different color patterns of H. axyridis. Among them, ten candidate AFLP markers were color-linked. S1, S2, and S20 markers were detected in Succinea 1 and 2 variants of H. axyridis, whereas S3 and S5 were specifically detected in the Conspicua variant. S15, S18, and S19 were specific to the Succinea 2 variant. Polymerase chain reaction (PCR) products of these ten AFLP markers were sequenced. BLAST analysis of these sequences against the GenBank database revealed their homology to DNA fragments of unknown function. Based on the color-linked AFLP markers, sequence characterized amplified region (SCAR) markers were designed for PCR amplification of genomic DNA. Of the ten AFLP markers, five were successfully converted into SCAR markers, which could discriminate elytra color polymorphism in H. axyridis.

This paper investigates the color rank system of the Wonsam, ceremonial topcoat, worn as a court formal costume of the Joseon dynasty by analyzing the court costume system and the actual examples of wearing. The research shows that there were some discrepancies of the color rank of the Wonsam between the court costume system and the actual wearing examples. There were red, purple, blue, green, and black Wonsam in the Joseon dynasty. The color rank of the Wonsam is as follows: the Queen's color was red, the Crown Princess's was green and purple, the royal concubine's was usually green and blue, but they could wear purple when they won the King's favor. A prince's wife's was usually green, but she wore blue and purple if she became the mother of the King. The princess's was green, and the court lady's was green, blue, and black. In most cases, the textiles of Wonsam were made by silk with patterns, even though Joseon dynasty was ordered to use silks without patterns in court weddings and funeral ceremonies to avoid extravagance.
