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.

The Implantation Application of Traditional Chinese Calligraphy in Book Cover Design under Contemporary Aesthetic Trend

In the information age, the public’s aesthetic consciousness of art has changed dramatically, showing a new trend of pursuing abstraction and personalisation of art works. In this context, Chinese traditional calligraphy, which carries deep oriental cultural heritage and artistic taste, and is highly flexible and adaptable in terms of artistic form, has great application value in the field of book cover design. This paper first analyzes the trend characteristics of the development and transformation of public artistic aesthetic consciousness from the industrial era to the information age, and then explores the artistic form characteristics of traditional Chinese calligraphy, and proposes that traditional calligraphy has great application value in book cover design. Finally, several innovative and clever cases of incorporating traditional calligraphy into book cover design were highlighted, providing inspiration for design ideas and methods.

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.

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.

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.

Human Machine Interface with Wearable Electronics Using Biodegradable Triboelectric Films for Calligraphy Practice and Correction

Letter handwriting,especially stroke correction,is of great importance for recording languages and expressing and exchanging ideas for individual behavior and the public.In this study,a biodegradable and conductive carboxymethyl chitosan-silk fibroin(CSF)film is prepared to design wearable triboelectric nanogenerator(denoted as CSF-TENG),which outputs of V_(oc)≈165 V,I_(sc)≈1.4μA,and Q_(sc)≈72 mW cm^(−2).Further,in vitro biodegradation of CSF film is performed through trypsin and lysozyme.The results show that trypsin and lysozyme have stable and favorable biodegradation properties,removing 63.1%of CSF film after degrading for 11 days.Further,the CSF-TENG-based human-machine interface(HMI)is designed to promptly track writing steps and access the accuracy of letters,resulting in a straightforward communication media of human and machine.The CSF-TENG-based HMI can automatically recognize and correct three representative letters(F,H,and K),which is benefited by HMI system for data processing and analysis.The CSF-TENG-based HMI can make decisions for the next stroke,highlighting the stroke in advance by replacing it with red,which can be a candidate for calligraphy practice and correction.Finally,various demonstrations are done in real-time to achieve virtual and real-world controls including writing,vehicle movements,and healthcare.

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.
