Generative adversarial networks based motion learning towards robotic calligraphy synthesis

Robot calligraphy visually reflects the motion capability of robotic manipulators.While traditional researches mainly focus on image generation and the writing of simple calligraphic strokes or characters,this article presents a generative adversarial network(GAN)-based motion learning method for robotic calligraphy synthesis(Gan2CS)that can enhance the efficiency in writing complex calligraphy words and reproducing classic calligraphy works.The key technologies in the proposed approach include:(1)adopting the GAN to learn the motion parameters from the robot writing operation;(2)converting the learnt motion data into the style font and realising the transition from static calligraphy images to dynamic writing demonstration;(3)reproducing high-precision calligraphy works by synthesising the writing motion data hierarchically.In this study,the motion trajectories of sample calligraphy images are firstly extracted and converted into the robot module.The robot performs the writing with motion planning,and the writing motion parameters of calligraphy strokes are learnt with GANs.Then the motion data of basic strokes is synthesised based on the hierarchical process of‘stroke-radicalpart-character’.And the robot re-writes the synthesised characters whose similarity with the original calligraphy characters is evaluated.Regular calligraphy characters have been tested in the experiments for method validation and the results validated that the robot can actualise the robotic calligraphy synthesis of writing motion data with GAN.

The Meaning Composition of Chinese Calligraphy Sign

This paper clarifies the composition of meaning in the art of Chinese calligraphy on the basis of American semiotician Charles Morris’s three divisions of sign,namely,“Syntactics,Semantics,Pragmatics”.The syntactical dimension of Chinese calligraphy sign is the artistic meaning of the form of Chinese character.“Semantical dimension”refers to semantic referents of linguistic signs and their literary significance,“pragmatical dimension”refers to the use and interpretation of calligraphy.The study of the three dimensions of meaning in Chinese calligraphy reveals a complex and unique composition of sign meaning.Chinese calligraphy deforms the structure and form of Chinese characters while retaining their semantic invariance.In this way,calligraphy acquires more practical semantic and symbolic meanings through the carrier of Chinese characters which are also linguistic symbols at the same time.Chinese calligraphy is dominated by the meaning of sign forms,taking into account the linguistic reference and the use of sign,and the three dimensions of meaning interact and promote each other,building a dynamic and multidimensional space of sign meaning.

Relationship between Calligraphy and Meteorology

Since ancient times,calligraphy and meteorology have had an inseparable relationship.Wang Xizhi s Prologue to the Collection of Poems Composed at the Orchid Pavilion records the beautiful scenery of mild wind and bright sun,as well as the relaxed and joyful mood of people in such weather.Su Shi s Cold Food Calligraphy Copybook records the scenery of solar terms and the author s psychological changes during these solar terms through calligraphy.The Quick Snow and Clear Time Calligraphy Copybook also reflects the grandeur of snowy days and the customs of literati recording weather and sharing it with friends.In Sun Guoting s Shupu,it is clearly stated that the third element of the"five harmony and five obedience"refers to the clear sky,humid air,and pleasant climate,and excellent climatic conditions are conducive to writing.

Application of Choquet Integral-Importance-Performance Analysis and TOPSIS Methods in Approaching the Preference Factors of Calligraphy and Seal Engraving Imagery

Classical Chinese characters,presented through calligraphy,seal engraving,or painting,can exhibit different aesthetics and essences of Chinese characters,making them the most important asset of the Chinese people.Calligraphy and seal engraving,as two closely related systems in traditional Chinese art,have developed through the ages.Due to changes in lifestyle and advancements in modern technology,their original functions of daily writing and verification have gradually diminished.Instead,they have increasingly played a significant role in commercial art.This study utilizes the Evaluation Grid Method(EGM)and the Analytic Hierarchy Process(AHP)to research the key preference factors in the application of calligraphy and seal engraving imagery.Different from the traditional 5-point equal interval semantic questionnaire,this study employs a non-equal interval semantic questionnaire with a golden ratio scale,distinguishing the importance ratio of adjacent semantic meanings and highlighting the weighted emphasis on visual aesthetics.Additionally,the study uses Importance-Performance Analysis(IPA)and Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)to obtain the key preference sequence of calligraphy and seal engraving culture.Plus,the Choquet integral comprehensive evaluation is used as a reference for IPA comparison.It is hoped that this study can provide cultural imagery references and research methods,injecting further creativity into industrial design.

The Aesthetic Connotation of Ancient Calligraphy

From the origin of writing to the formation of the writing system,the names and aesthetics of calligraphy have been evolving with time.Calligraphy has different mainstream writing styles across different eras and has been assigned different names,which also maps the aesthetic orientation of the times.Not only is calligraphy the evolution of the designation of successive generations but also in the continuous pursuit of“name”and“reality”of the unity of the ancient connotation of calligraphy and the era of aesthetic integration.This paper discusses the flavorful meaning behind the concept of ancient calligraphy,as well as its various forms of expression.

Contemporary Chinese Calligraphy Between Tradition and Innovation

Since the mid-1980s Chinese calligraphy art has undergone a radical change and has opened itself to experimentation. A vivid debate on CCC （Contemporary Chinese Calligraphy） （Zhongguo xiandai shufa） is involving art critics in China nowadays. WANG Dongling and the modernists think that, despite many changes and influences, we can still refer to the traditional calligraphic lexicon to describe the calligraphic production of contemporary Chinese art. They still remain deeply rooted in the signified system of Chinese writing, even if they break with the strict rules of Chinese classical aesthetic （contamination of Western elements and focus on the stylistic exploration）. WANG Nanming and the Avant-garde think that ＂contemporary calligraphy is not calligraphy yet＂： It is ＂anti-calligraphy＂, annihilates Chinese tradition, rejects the use of legible characters, experiments with new languages and new media within the idiom of international contemporary art. The result is the creation of works of art that could be assimilated to Abstract art, Abstract expressionism, Conceptual art, Performance art, Contemporary dance, Multimedia art, and even Street art. This paper aims at showing how still valid and extremely productive are both these two theoretical and creative/practical approaches to Chinese calligraphy in China nowadays. They turned the art of calligraphy into a medium for global comprehension and communication.

Chinese Calligraphy Word Spotting Using Elastic HOG Feature and Derivative Dynamic Time Warping

Chinese calligraphy is a very special style of handwriting and direct character recognition is very difficult. Content-based keyword spotting is more feasible than recognition-based retrieval for calligraphy document. In this paper,we propose a novel Elastic Histogram of Oriented Gradient( EHOG) descriptor for calligraphy word spotting. The presented feature is a modification of Histogram of Oriented Gradient( HOG), widely used in human detection. In our approach,the input word image is partitioned into non-uniform rectangular cells according to the calligraphy character pixel intensity,and then in each cell a histogram of orientation is accumulated dynamically. Moreover,we adopt Derivative Dynamic Time Warping( DDTW) for image feature matching,which achieves good performance in gesture recognition. Experiments demonstrate a very significant improvement when comparing our proposed feature with previously developed ones,and also show DDTW produces superior alignments between two calligraphy character feature series than DTW.

A Study on Quantitative Evaluation of Calligraphy Characters

In this study, a numerical method was proposed to evaluate the calligraphy work called calligraphy evaluation system. Four classical chirographies of ＂Kaisho＂, ＂Gyosho＂, ＂Sousho＂ and ＂Hiragana＂, and 47 characters for each chirography, were selected and analyzed by this system. The ＂Sumi＂ distribution of character was clarified from 12 directions and summarized into four parts of horizontal part, diagonal left part, vertical part and diagonal fight part. The character＇s contour line was converted to a signal data in order to calculate roundness index. The degree of character＇s radian was presented by roundness index. The smooth index was calculated at the same time. Additionally, width index, ＂Sumi＂ ratio, stability index also were calculated to contrast the features of each style. The main character points of four styles of ＂Kaisho＇, ＂Gyosho＂, ＂Sousho＂, ＂Hiragana＂ were extracted to compare each other, and provide a reference for learners. The learners could obtain the quantitative data to understand their work＇s characteristics. It can also be compared with other person＇s work by this system in order to improve learners＇ writing skill.

Body: A New Issue in Contemporary Calligraphy Aesthetics

With the development of new media, an important dimension of contemporary calligraphy has been highlighted, namely the body. One of the most intriguing phenomena of the body is the video of some calligraphy creations on the Internet. The exaggerated body movements and performances have caused heated discussion among the calligraphy circles and many netizens. However, the critics still lack deep and comprehensive thinking about the problems related to the body in calligraphy. We believe that the physical dimension of calligraphy refers to the appearance of the body in the practice of calligraphy in three ways: experience, imagery, and performance. Through the consideration of the body dimension of calligraphy, this article tries to put forward the general criticism of the calligraphy works and the creative practice of physical phenomena. It should be divided into the following parts. One of them is that this kind of physical phenomenon expresses the spirit of the times and expresses the individual "feeling";"sorrow and joy" is helpful;the second is the merits and demerits of the work itself, and the third is the relationship between the generation of the work and the body and the degree of harmony.
