In this paper, we propose a method to improve JBIG2 compression ratio which can be applied to Hangul text. Hangul character is composed of a few symbols which is called JASO, which needs inevitable increase of position information to be transmitted. To reduce this disadvantage, we have proposed an algorithm that generate aggregated symbol in combination of JASO symbols. Proposed algorithm shows better performance in Huffman coding than in arithmetic coding. In lossless coding, proposed algorithm showed 4.5∼16.7(%) improvement for Huffman coding and 2.9∼10.4(%) improvement for arithmetic coding. In lossy coding, proposed algorithm showed 3.7∼17.0(%) improvement for Huffman coding and 2.1∼10.5(%) improvement for arithmetic coding.

본 논문에서는 지도 정보를 자동으로 분석하여 등고선과 숫자, 기호를 추출해 내는 알고리즘에 대해 연구하였다. 이를 위해 우선 지도를 이진 영상으로 변환한 후 세선화 작업을 거친다. 세선화된 영상으로부터 등고 성분들을 분리시킨 후, 비등고 성분에 대한 특징분석 후 숫자와 기호를 자동으로 분리한다. 마지막으로 복원 알고리즘을 이용하여 손실 부분을 복원한다. 여러 종류의 등고선 지도영상을 대상으로 모의실험을 수행하여 제안한 알고리즘의 성능을 검증하였다.

Recognition systems for scanned or printed music scores that have been implemented on personal computers have received attention from numerous scientists and have achieved significant results over many years. A modern trend with music scores being captured and played directly on mobile devices has become more interesting to researchers. The limitation of resources and the effects of illumination, distortion, and inclination on input images are still challenges to these recognition systems. In this paper, we introduce a novel approach for recognizing music scores captured by mobile cameras. To reduce the complexity, as well as the computational time of the system, we grouped all of the symbols extracted from music scores into ten main classes. We then applied each major class to SVM to classify the musical symbols separately. The experimental results showed that our proposed method could be applied to real time applications and that its performance is competitive with other methods.

In this paper we embody a system that recognizes printed alphabet, numeral figures and symbols written on the keyboard for the recognition of English sentences. The image of the printed sentences is inputted and binarized, and the characters are separated by using histogram method that is the same as the existing character recognition method. During the abstraction of the individual characters, we classify one group that has not numerical information by the projection of the vertical center of the character. In case of another group that has the longer width than the height, we assort them by normalizing the width. The other group normalizes the height of the images. With the reverse application of the basic principle of the Japanese Puzzle to a normalized character image, the proposed system classifies and recognizes the printed numeral figures, symbols and characters, consequently we meet with good result.

본 논문에서는 신경회로망 알고리즘 중 하나인 backpropagation network을 이용한 악보인식 기법과 그에 필요한 악보 영상에 대한 전처리 기법을 제안한다. 전처리과정으로 이진화, 기울기 보정, 오선제거 등의 과정을 수행하여 인식에 필요한 음악 기호와 음표를 분리한다. 분리된 음악 기호와 음표들은 backpropagation 알고리즘을 사용하여 구성된 음표 인식 신경망과 비음표 인식 신경망을 통해 각각 음표와 비음표 인식과정을 거친다. 다양한 복잡도를 가진 악보를 대상으로 한 실험 및 분석 결과를 통해 제안한 악보 인식 기법의 정확도를 기술하였다.

This study studied the seasons in the novel Snowy Read and the archetypal characteristics in natural phenomena. Summer and winter are the main seasons of Snowy Road. The cycle of the day is the time of dawn and early morning, evening, or night. It is summer now, and memory day is winter. In Snowy Road, 'I' is in sharp conflict with my mom during the summer season. This conflict is resolved and resurfaced with the feeling of 'love' as the story of the day is told in the mother's memory. It was a long time of conflict and trials for winter in the memory of me and my mother. As a result of examining the circular symbols in the Snowy Road, each symbol represents the 'I' and 'the mother's feelings'. 'I' and 'Mom's Emotions' collide, but they confirm each other's sincerity and rebuild their feelings of conflict with 'love'. In Snowy Road, the mother and son's 'love' shows that the mother's son is deeply in love, but the son's mother's love is also very deep.

The purpose of this paper is to summarize the cursive script of traditional calligraphy and develop further possibilities based on the study of the painting and postscript of Ink bambooo, which was painted by wu zhen(吳鎮) during the Yuan Dynasty. The second section in this paper provides a summary of wu zhen(吳鎮)'s life, in addition to "Ink bambooo" and its painting postscript. The third and fourth sections are focused on analyzing the cursive script in the painting postscript of Ink bambooo, including the left-and-right structure, head prefix symbols, and bottom prefix symbols. The aim of this paper is the study of cursive script, and the theories and methods of the characters proposed by Dr. Cai Yonggui (from Fujian Normal University) and Dr. Liu Dongqin (from Southeast University) will be used to provide a summary. The presentation of the research results of this paper is designed to develop further possibilities for this type of traditional calligraphy.

As a new marketing tool, gamification design has been used in marketing practice by e-commerce platforms, aiming to motivate consumers to participate. Based on this, by sorting out relevant domestic and foreign literature, analysis of actual business cases, in-depth interviews with users, experiments and data analysis, this study extracts and describes in detail the elements of the e-commerce platform gamification incentive mechanism. Draw conclusions through research: (1) The incentive mechanism of gamification design of e-commerce platform contains four main dimensions : The richness of symbols, The fun of gamification, The contagiousness of Social and The seduction of achievement. (2) The four elements are closely related, and these can work on a system at the same time and have significant mutual effects. (3) Achievement and fun can bring intrinsic motivation to consumers, while sociability and symbols can bring external motivation to consumers and promote internal motivation through external motivation. (4) The seduction of achievement and the richness of symbol are most closely related.

In this paper, we design a Circle dot Code, In our scheme, we design a dot patterns for increasing maximum capacity and also for increasing robustness to Affine Transformation. Our code Can be extended according number of data circle. We use three data circle vision code. In this type code, after acquiring camera images for the Circle dot Codes, and perform error correction decoding using four position symbols and six CRC symbols. We perform graph based dot code analysis which determines the topological distance between dot pixels. Our code can be bridged the real world and ubiquitous computing environment.

This article explores religious responses to significant cultural and social change in a northern Vietnamese delta village from 1996 to 2008-the second decade after de-collectivization. Drawing upon extensive fieldwork in both the village and surrounding religious networks, the article teases out the meanings of the new religious movements for northern rural people in the new era of market economy; the symbols, language, and metaphoric resources people used in response to their uncertainty and mistrust of the new social landscape; and the unintended consequences of rapid societal development such as marginalization, tensions, and social disintegration. The article argues that as in milleniarism elsewhere, new religious movements in northern rural Vietnam embody unorthodox syncretism between world religious and local traditions, thus linking past, present, and future. However, when drawing upon a common reservoir of memories and experiences to cope with risks and challenges of the new market world, local people not only drew on the power and imperial metaphor of deities in their traditional religion and belief, but became more creative to recuperate meanings, standards, and symbols from revolutionary discourse to reorient themselves, and overcome alienation and marginalization.
