As time goes on, that becomes an issue still more for truth from error of a seal in electronic settlement , or in important document in the field of image recognition. But on the other hand image treatment method of a seal have has the weakness until now. It makes indistinct distinction of part that light and darkness is changed sharply as the edge of things. So it has difficult that edge detection is extracted. In this paper, I investigated the pixel in a specific area by using enhanced smothing method and searched a value of frquent occurrence. The value of pixel is substituted and edge detection is extracted. After then it could be classified rightly according as viligence test is dynamically changed. I applied conventional of Yager's generated intersection operator among fuzzy logic operator in ART1 learning Algorithm. Application of suggested ART1 learning algorithm, it results in improved image recognition rate than a case of using the conventional ART1 algorithm

The pixel art style evolved from the shortcomings of computer image display technology has gradually transformed from a technical limitation into a widely recognized form of artistic expression since development in the early 20th century. This study analyzes the application and characteristics of the expandability of pixel art style design content in sub industries such as physical goods, environmental design, website design, digital art and illustration in the design field. It aims to explore the visual expression and sustainable development form of pixel art style under the development of new media technology that contradicts traditional technological concepts. The research results show that although the pixel art style generally pursues external visual features such as pixelated visual effects, sawtooth and matrix arrangements, its expansion in the art field shows a unique diversity of visual expressions. It has become an important means to convey nostalgic emotions and cultural values. Through this research, we hope to inspire more academic researchers and technology practitioners to explore the development potential of the pixel art style in emerging fields and promote its innovative application in design practice.

시간이 부족한 현대인과 보살핌이 부족한 고령화 인구의 증가로 인해 비교적 가벼운 질병을 방치해 더 큰 고통을 겪는 경우가 발생하여 직접 병원에 가지 않고 자신의 건강 상태를 파악할 수 있는 시스템의 개발이 필요하게 되었다. 하지만 질병의 특성상, 증상의 차이와 구분에 의해 같은 질병이라도 다른 치료와 예방이 필요하고 다른 질병으로 세부 도출될 가능성이 있다. 따라서 증상의 차이를 고려하지 않고 단순한 증상의 선택만으로 도출된 결과는 상황을 더욱 악화시킬 가능성이 있다. 본 논문에서는 ART2 알고리즘을 이용하여 질병을 도출하고 증상의 차이를 구분하기 위해서 애매한 증상의 정도를 퍼지 소속 함수로 표현하고 퍼지 추론 방법을 적용하여 더욱더 정확한 질병 상세를 도출 할 수 있는 개선된 자가진단 시스템을 제시한다. 본 논문에서 제안한 방법을 전문의에게 분석을 의뢰한 결과, 본 논문에서 제안된 자가진단 시스템 방법이 이전의 방법보다, 지능형 자가 보조 진단 시스템으로서 사용자에게 더욱 효과적인 도움을 줄 수 있다는 가능성을 확인하였다.

In this paper, we propose a portable art therapy content. The proposed content makes counseling clients get a psychical cure at least cost regardless of time and place Counseling clients express their psychological state as pictures through the proposed content. And Counselors analyze and interpret the figures based on the database which is built into the server system. Due to the development of advanced technologies, various adjustment disorders and addictions have increased in the rapidly changing modern society. This causes the increase of counseling clients who want a psychical cure. And also counseling time, counseling place and counseling cost are emerging as a social issues. Psychotherapy specialists use the proposed content at the stage of the psychoanalysis which needs a lot of time and effort. The proposed content exploits the sever system to make the right decisions quickly and accurately. Counseling clients who are the medical underprivileged get visit consultation and online consultation can detect a psychological high-risk in an early stage and prevent this psychological high-risk. Preventive treatment service using the proposed content will make the social and medical cost savings.

본 논문에서는 충치 환자의 진단을 위해 구강 영상에서 충치를 추출하는 방법을 제안한다. 먼저 구강은 붉은색을 띄고 치아는 흰색을 띈다는 특징이 있기 때문에, 구강 영상을 YCbCr 컬러모델로 변환한다. YCbCr 컬러모델에 임계치를 설정하여 붉은 영역을 검출해내고, 검출된 붉은 영역에 대해 이진화하여 치아 영역을 추출한다. 그 후, 모폴로지 기법을 이용하여 잡음 제거 및 치아의 빈 공간을 채운다. 치아 영역 추출 시 영상에 따라 치아 사이를 잇는 모서리 부분이 손실된 경우가 발생할 수 있기 때문에 치아 사이의 손실된 부분을 연결 한다. 치아 영역에 ART2 알고리즘을 적용하여 클러스터링하고 충치 후보 영역을 추출한다. 충치 후보 영역에 8방향 윤곽선 추적 기법을 적용하여 충치를 분석 및 추출한다. 실험 결과 81%의 추출 성공률을 보였고 다양한 형태의 충치를 효과적으로 추출할 수 있는 것을 확인하였다.

Clustering plays an indispensable role for data analysis. Many clustering algorithms have been developed. However, most of them suffer poor performance of learning. To archive good clustering performance, we develop a hybrid neural network model. It is the combination of Multi-Layer Perceptron (MLP) and Adaptive Resonance Theory 2 (ART2). It inherits two distinct advantages of stability and plasticity from ART2. Meanwhile, by combining the merits of MLP, it improves the performance for clustering. Experiment results show that our model can be used for clustering with promising performance.

The Post-clustering algorithms, which cluster the results of Web search engine, have several different requirements from conventional clustering algorithms. In this paper, we propose the new post-clustering algorithm satisfying those requirements as many as possible. The proposed Concept ART is the form of combining the concept vector that have several advantages in document clustering with Fuzzy ART known as real-time clustering algorithms. Moreover we show that it is applicable to general-purpose clustering as well as post-clustering

Stage lighting system is very important in theater. Because basic of performing art. Recently, The stage lighting system is very close with a performing arts. The performance arts is to have an easy communication between actors and audience. All activities related to performance art take place between the stage light and auditorium. Therefore, when constructing theater the best conditions of the stage light system should be considered for the smooth progress of play. It will be method of solution that basically facility in the performance art hall. The results of this study can be used for suggesting an operation and system improvement for stage lighting system in performance art hall. Recently, changes in the progress of plays have required the perfect stage light system. As a result, performance art hall are the most advanced stage lighting system technology of changed. The following procedures were taken for this research-the literature on the development of stage lighting system and equipment, structure, and the dimmer and computer console system has been reviewed theoretically Most of all, Cheonan City Hall Bongseo Hall and CMB EXPO art hall is important a sample of lighting system. The result of this study presents operation and system improvement stage lighting system in theater, below to operation and system improvement at stage lighting system local self-government corporation performance art hall are inconsistent stage.

Generative Art (also called as the art of the algorithm) creates unexpected results, moving autonomously according to rules or algorithms. The evolution of digital media in art, which tries to seek novelty, increases the possibility of new artistic fields; subsequently, this study establishes the basis for new design approaches by analyzing visual cases of Generative Art that have emerged since the 20th century and characteristics expressed on fashion. For the methodology, the study analyzes fashion designs that have emerged since 2000, based on theoretical research that includes literature and research papers relating to Generative Art. According to the study, expression characteristics shown in fashion, based on visual properties of Generative Art, are as follows. First, abstract randomness is expressed with unexpected coincidental forms using movements of a creator and properties of materials as variables in accordance to rules or algorithms. Second, endlessly repeated pattern imitation expresses an emergent shape by endless repetition created by a modular system using rules or 3D printing using a computer algorithm. Third, the systematic variability expresses constantly changing images with a combination of system and digital media by a wearing method. It is expected that design by algorithm becomes a significant method in producing other creative ideas and expressions in modern fashion.
