Problems solved by technology

In the existing design research, a certain amount of basic elements are provided to reduce the workload of the designer, but the overall composition and layout still needs to be completed manually. In addition, the natural communication gap between the designer and the user makes it difficult for the design to meet diverse, complex, and individual needs. Customized customer psychological needs
In short, complex ethnic patterns such as batik are difficult to express with mathematical models, and cannot meet the changing, vague and personalized needs of customers

Embodiment

[0038] 1. Parametric pattern design based on shape grammar

[0039] Computer-aided systems based on shape grammars have high-quality properties in automatic design, but the bottlenecks in initial shape matching, replacement shape recognition, and shape transformation control cause disadvantages in the implementation of design systems. According to the characteristics of batik pattern, its generation process can be described by shape grammar.

[0040] 1.1 Analysis and extraction of batik pattern features

[0041] 1.1.1 Pattern composition feature analysis and functional information acquisition

[0042] Traditional batik is a wax-resistant dyeing technique applied to a whole piece of cloth, or cloth made using this technique. The pattern is traced in pencil and then redrawn with a wax knife and hot wax. Batik in Guizhou has strong national cultural characteristics in terms of shape, color, and pattern. It generally has different functions and meanings such as praying for bles...

Abstract

The invention discloses a pattern design method based on shape grammar and a neural network. The pattern design method comprises the following steps: step 1, carrying out pattern parameterization based on shape grammar: 1) feature analysis and extraction; 2) rule definition and coding method construction; 3) rule reuse and parameter evolution generation design; 4) detecting and visualizing of a rule reuse result; step 2, constructing a user visual cognition image space through acquisition of a pattern composition sample and quantification of a visual cognition image; and step 3, constructing aneural network-based design parameter and style imagination relationship model, optimizing the neural network relationship model by using a genetic algorithm to obtain an optimal pattern design parameter, and completing pattern design. The method has the advantages that the optimal design parameter solution meeting the imagination value can be provided, and the style imagination requirements of consumers are met.

Description

technical field [0001] The invention relates to the field of pattern design, in particular to a pattern design method based on shape grammar and neural network. Background technique [0002] Batik is one of the traditional handicrafts of ethnic minorities in Guizhou, China. It has distinct regional and ethnic characteristics and the value of artistic and cultural inheritance. Traditional batik patterns are mainly drawn by craftsmen using wax knives based on design experience. It is not easy to quickly generate patterns, and it is difficult to adapt to today's competitive market environment that requires individualization and differentiation. The combination of advanced technology and traditional art is a common idea of ​​modern design. Computer-aided digital printing and dyeing technology provides a new direction for traditional art pattern design, but there is a lack of related research in the field of batik. In the prior art, some scholars have proposed "imitation batik" ...
