Problems solved by technology

The pattern synthesized by this method has partial overall similarity with the sample, but because the spatial position relationship of various pattern elements is not considered, this method is only suitable for pattern synthesis without clear internal structural features

Embodiment Construction

[0032] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0033] figure 1 Given a typical hand-painted pattern example, the flow of the hand-painted pattern synthesis method is as follows figure 2 As shown, it is divided into three modules: sample drawing, sample analysis and pattern synthesis. The process has the following steps in sequence:

[0034] 1. Sample drawing module: Use the digital tablet to draw pattern samples, monitor and obtain drawing tablet information through the Wintab interface. The pattern sample is described by the three-level structure of point, stroke and pattern element.

[0035] 1) Whenever the tablet returns a message, extract the three data items of abscissa, ordinate, and pressure sensitivity in the message and record them as a sampling point.

[0036] 2) All the sampling points recorded during the process from when the pen tip falls on the digital board to when the pen tip ...

Abstract

The invention provides a synthesis method of a hand painted pattern, relating to a pattern synthesis technology and providing a synthesis method of a hand painted pattern according to human vision mechanism features. The synthesis method comprises the following steps of: painting a pattern sample by using a digitizer; inputting the size of a synthesis pattern; clustering pattern elements in the pattern sample, and classifying each pattern element in the pattern sample into an element category; analyzing distribution features of the pattern elements; placing seed points to generate a seed drawings; constructing a mapping relation; mapping each seed point to one element category; and displacing each seed point into one pattern element to synthesize the pattern. The synthesis method can obtain the large-scale synthesis pattern similar to the pattern sample on the visual perception and overcomes the defects of the hand painted pattern. Compared with the pure hand painting method, the synthesis method can greatly improve the painting efficiency. The synthesized pattern has not periodic repeat on the structure. Compared with the traditional square continuous method, the synthesis effect is more vivid. Compared with a texture synthesis method, the synthesized pattern is more accordant with the human vision cognition low.

Description

technical field [0001] The invention relates to a pattern synthesis technology, in particular to a pattern synthesis method for generating large-scale new patterns by using hand-painted decorative pattern samples. Background technique [0002] In recent years, with the continuous development of multimedia technology, the computer drawing environment has become more and more perfect. Drawing equipment such as digital boards, digital screens and stylus pens, which are convenient for art designers to create, have been widely used, and a large number of pattern creation and design work has begun to be completed on computers. . Texture synthesis technology can mosaic and synthesize a large-scale texture similar to the specified texture sample through color matching of adjacent regions (Zhu Wenhao, Wei Baogang. A review of sample-based texture synthesis technology. Chinese Journal of Image and Graphics, 2008.13(11 ):2063-2069), but this technique does not treat the perceptual ele...
