基于统计模型的书法创作模拟

人们对抽象思维与形象思维的认识极不平衡,对形象思维过程的研究尚属阙如.书法创作是典型的形象思维过程.文中给出基于带参数的统计模型(X=M(b))的书法笔划变形方法,通过调节参数可生成新风格的笔划.其过程包括从笔划轮廓获得训练点集、利用广义Procrustes分析法对齐、由主成分分析法得到特征等,并以隶书中典型的"一"划为例,讨论模拟创作结果.要实现人工智能,形象思维的模拟、模式和模型是逐步要考虑的问题.目前的工作只是第一步.

Statistic Model-Based Simulation on Calligraphy Creation

Calligraphy is classic course of imagery thinking.The authors manage to create new stroke shape of calligraphy character based on a statistical model with parameter:X=M(b).Where X is target stroke with new styles and parameter b is a vector to adjust the stroke features(e.g.long or short of the stroke).When the parameter is changed with some specific values,new style could be generated.Therefore,some samples are selected in order to form a training set.Each of them is marked with several points,including the points on the contour and the control points which will be used by generating the consecutive contour curve later.After that,the training set is aligned by using Generalized Procrustes Analysis and the primary features of these samples are extracted by Principal Components Analysis.Later on,a few characteristic features in the training set are extracted and represented by the form of several eigenvectors.With the extracted features,new styles of strokes can be generated.Then,stroke one(Horizontals)in "Li" style of Chinese calligraphy is illustrated with simulation results.Simulation of intelligence,patterns of imagery thinking and model of cognition are key issues here.Current work is only the first step.
