Experimental Research On The Characteristics Of Freehand Chinese Signature Drawing Handwriting

This paper mainly focuses on the empirical research on the characteristics of freehand Chinese signature drawing handwriting.Among document inspection and identification,handwriting identification is a very important part,among which the handwriting identification cases of signature are most.Signature handwriting usually appears on debits,receipts,bills and contracts.The number of characters is relatively small,and it is easier to obtain.Therefore,illegal elements impersonate the signed handwriting for the purpose of seeking economic benefit and so on.But the ways of imitation are not the same.Gradually imitation signature handwriting has become the key difficulty of handwriting identification in recent years.Freehand Chinese signature drawing handwriting is a kind of imitation signature handwriting,that is,using the way of drawing to imitate Chinese signature.This kind of imitation signature handwriting is very commonly in handwriting identification cases.Imitators temporarily simulate others signature handwriting because of economic disputes,cover-up of criminal facts and other reasons.Experts of relevant specialties have done in-depth researches on different kinds of imitation signature handwriting,but at present there is still a lack of comprehensive and systematic analysis of the characteristics of freehand Chinese signature drawing handwriting.On the basis of the existing research results,the author wants to study the Characteristic of freehand Chinese signature drawing handwriting.In view of this,the author starts from the theoretical basis of freehand Chinese signature drawing handwriting,expounds the concept,classification,formation mechanism and scientific basis of freehand Chinese signature drawing handwriting identification.And then applies the method of experimental analysis,based on the design of experimental conditions,the experimental samples of different kinds of freehand Chinese signature drawing handwriting are counted and analyzed,including the similarity of freehand Chinese signature drawing handwriting,the comparative analysis of imitation characteristics and the analysis of the influencing factors of the experiment.Finally,according to the experimental results,the paper discusses the characteristics analysis,recognition method and key points of verification and identification of freehand Chinese signature drawing handwriting.This paper expects to be able to identify imitation modes,to provide a train of thought for improving imitation signature handwriting identification theory and provide a reference basis for freehand Chinese signature drawing handwriting identification practice.This paper consists of three chapters.The first chapter is primarily talking about the theoretical research of freehand Chinese signature drawing handwriting,which is divided into two sections.The first section discusses an overview of freehand Chinese signature drawing handwriting,mainly including the concept,classification,imitation characteristics and research status of freehand signature drawing handwriting;The second section describes the scientific basis on identification of freehand Chinese signature drawing handwriting,and expounds the formation mechanism of freehand Chinese signature drawing handwriting and scientific basis of this kind imitation handwriting identification.The second chapter discusses the experimental research and analysis of freehand Chinese signature drawing handwriting,which is divided into three sections.The first section is the experiment on freehand Chinese signature drawing handwriting,mainly elaborating the purpose and significance of experiment and experiment condition and method;The second section is about the statistics and analysis of the similar characteristics of different kinds of freehand Chinese signature drawing handwriting.First,collecting experimental samples and making the data statistics.Then,making an experimental analysis and discussion on the similarity of handwriting characteristics of different kinds of freehand Chinese signature drawing handwriting,and analyzing of experimental factors.The third section is related to the comparison and analysis of freehand drawing characteristics occurrence rates of different kinds of freehand Chinese signature drawing handwriting,discussing the difference of the occurrence rate of the freehand drawing characteristics of freehand Chinese signature drawing handwriting,analyzing the influencing factors of the experiment.The third chapter writes about a study on the identification of freehand Chinese signature drawing handwriting,which is divided into two sections.The first section is about the recognition of freehand Chinese signature drawing handwriting,which mainly includes the ways to make an accurate recognition and the identification conditions requirement of freehand Chinese signature drawing handwriting;The second section is talking about the verification and comprehensive evaluation of feature of the freehand Chinese signature drawing handwriting,and expounds the way to exam the characteristics of samples and discusses the comprehensive evaluation of handwriting characteristics.
