  • The image interpolation is one of an image preprocessing process to heighten a resolution. The conventional image interpolation used much to concept that it put in other pixel to select the nearest value in a pixel simply, and use much the temporal object interpolation techniques to do the image interpolation by detecting motion in a moving picture presently. In this paper, it is proposed the image interpolation techniques using the fuzzy wavelet base function. This is applied to embody a correct edge image and a natural image when expand part of the still image by applying the fuzzy wavelet base function coefficient to the conventional B-spline function. And the proposal algorithm in this paper is confirmed to improve about 1.2831 than the image applying the conventional B-spline function through the computer simulation.

  • Although image compression is one of the essential technologies to transmit image data on a variety of surveillance and mobile healthcare applications, it causes unnecessary compression artifacts such as blocking and ringing artifacts by the lossy compression in the limited network bandwidth. Recently, image restoration methods using convolutional neural network (CNN) show the significant improvement of image quality from the compressed images. In this paper, we propose Image Denoising Convolutional Neural Networks (IDCNN) to reduce the compression artifacts for the purpose of improving the performance of object classification. In order to evaluate the classification accuracy, we used the ImageNet test dataset consisting of 50,000 natural images and measured the classification performance in terms of Top-1 and Top-5 accuracy. Experimental results show that the proposed IDCNN can improve Top-1 and Top-5 accuracy as high as 2.46% and 2.42%, respectively.

  • This study examined recycled fashion design utilizing natural images for application to recent trends. This study is significant in that it presents the possibility of the development of recycled women's wear design by reflecting the characteristics and expressions of natural images and using denim material, which is the most common clothing material for everyday life. The results of this study are summarized as follows. First, five types of women's clothing was produced, pursuing a natural design with a soft and feminine silhouette. Second, the colors used were blue and white, which could represent nature. Third, as for materials, this study used clothing that was to be thrown away: four pairs of denim pants and two denim dresses. This study chose denim cloth, with its great value for reuse, because of the characteristics of the strong and durable fiber, because everyone has more than one article of clothing made from denim and because it can be easily sourced. Fourth, for textile motifs, this study expressed a peaceful natural scenery with tropical animals and plants. In addition, this study further emphasized natural images using transfer media printing. This study has significance in that it presented the possibility of recycled fashion design and expanded the range of utilization using transfer media printing, a dyeing treatment to reduce the environmental burden.

  • Biophilic design gives human beings positive and valuable experiences in nature. The experience in nature in the architectural environment is mainly symbolic and metaphorical, and is based on visual sensations such as color, form, and image. Recently, modern people living in a modern and simple style indoor space have a desire to pursue visual stimuli for interest or pleasure. This desire can be satisfied through color, lighting, and finishing plan. Therefore, the purpose of this study is to propose a biophilic design color palette based on the empirical characteristics and properties of biophilic design. The methods used in this study are as follows. First, the biophilic design factors and natural landscape preference criteria are examined. Second, based on the review results, natural landscape images are selected and color information for each biophilic design element is extracted according to the vertical and horizontal directions. Third, color information is converted to NCS color code and palette range and hue range are derived through the analysis of ratio and average values. Finally, based on the analysis results, biophilic design color palette is proposed for each element. The results of this study might be useful as basic data in establishing biophilic design strategies and applying them to architecture and interior construction.

  • The purpose of this study was to examined which the pursuing image, make-up and hair style desire on their wedding day and how the future brides managed their appearance for the wedding. This qualitative research was based on the data collected by in-depth interviews with 15 brides in their 20s, 30s and 40s who reside in Daegu and Gyeongbuk. The results of the study are shown follow: The images that the brides most pursued for the wedding day were elegant images and refine images. The favorite wedding-dress styles of brides were elegant, refine, lovely, classical, and natural style in order of preference. The design of the dress was top priority when selecting the wedding-dress and it was followed by the function that complements anyones' shape. The brides liked natural style wedding make-up most and refine and young one followed. They considered eye make-up most important after skin expression, that is, covering defects of their skin. Concerning wedding hair styles, an up-style which is typical for wedding is desired most and a natural flowing hair style second. Regarding fitness, they mainly took physical exercise and went on a diet which is not unreasonably harsh.

  • The characterization of the ozone oxidation for raw natural rubber (NR) was investigated under controlled conditions through image and fourier transform infrared (FT-IR) analysis. The ozone oxidation was performed on a transparent thin film of raw NR coated on a KBr window in a dark chamber at $40^{\circ}C$ under low humidity conditions to completely exclude thermal, moisture, or light oxidation. The ozone concentration was set at 40 parts per hundred million (pphm). Before or after exposure to ozone, the image of the thin film for raw NR was observed at a right or tilted angle. FT-IR absorption spectra were measured in the transmission mode according to ozone exposure time. The ozone oxidation of NR was determined by the changes in the absorption peaks at 1736, 1715, 1697, and $833cm^{-1}$, which were assigned to an aldehyde group (-CHO), a ketone group (-COR), an inter-hydrogen bond between carbonyl group (-C=O) from an aldehyde or a ketone and an amide group (-CONH-) of protein, and a cis-methine group ($is-CCH_3=CH-$, respectively. During ozone exposure period, the results indicated that the formation of the carbonyl group of aldehyde or ketone was directly related to the decrement of the double bond of cis-1,4-polyisoprene. Only carbonyl compounds such as aldehydes or ketones seemed to be formed through chain scission by ozone. Long thin cracks with one orientation at regular intervals, which resulted in consecutive chain scission, were observed by image analysis. Therefore, one possible two-step mechanism for the formation of aldehyde and ketone was suggested.

  • 자연영상에 내포되어 있는 문자는 다양한 내용을 표현하는 중요한 정보이다. 기존의 문자 검출 알고리즘은 영상의 복잡도와 주변의 조명, 문자와 유사한 배경색 등의 환경에서 문자영역을 검출하지 못하는 문제점이 있으므로 본 논문에서는 에지 및 형태학적 재구성에 의한 연결요소를 이용한 자연영상에 포함된 문자영역을 검출하는 방법을 제안한다. 첫 번째 단계로, 명암도 영상에서 캐니에지(Canny-Edge) 검출기를 이용한 에지 성분과 형태학적 연산에 의한 지역적 최소/최대값을 갖는 연결요소를 검출하고, 각각 검출된 연결성분을 레이블링하고, 레이블링 된 각 성분에 대해 문자가 갖는 특징을 이용한 후보 문자영역을 검출한다. 마지막으로 검출된 후보 문자 영역을 서로 합병하여 하나의 후보 문자 영역을 생성하고, 후보 문자 영역의 인접성과 유사성으로 후보 문자 영역을 검증하여 최종 문자 영역을 검출한다. 실험결과 제안한 에지 및 연결요소 성분을 이용한 방법은 문자영역 검출의 정확성이 개선되었다.
