Problems solved by technology

These methods all start from the perspective of geometric space layout, and form different symmetrical or asymmetrical layout results by systematically repeating, transforming or cross-combining the basic geometric elements representing pattern instances, so the outer contours of the printed patterns are all Fixed, mostly rectangular, not able to generate decal layouts with more uniform instance distribution for user-defined non-rectangular pattern outlines

Embodiment

[0088] In this example, for Figure 2a and Figure 2b The input image set consists of two printed images, Figure 2c and Figure 2d The mask image generated after object segmentation, in which each white area represents a foreground object, iteratively performs pairwise matching similarity and finds Figure 3a The repeating object. In this embodiment, a total of 7 different types of repeated objects were found, which were rabbits, deer and five-pointed stars in five different forms. Figure 3b for Figure 3a The repeated objects correspond to the mask image. Figure 4a based on Figure 3b A template mesh composed of the resulting quadrilateral mesh. Figure 4a The outline of the target printing pattern input by the user is generated by performing quadrilateral mesh division on it Figure 4c the grid, and based on the quadrilateral grid and Figure 4a The template is generated by discrete compact layout solving Figure 4d For the optimal solution of the layout, a tota...

Abstract

The invention discloses a repeat mode discovery-based printed pattern generation method. The method comprises the following steps of: carrying out repeat mode discovery on an input printed image set so as to discover an object-class image mode which repeatedly emerges in the image set; constructing a layout template for a repeat object, carrying out multi-granularity quadrilateral mesh generation and optimum layout solution on the profile of an input printed pattern through iterative loop, and calculating an object optimum layout which satisfies a printed pattern constraint condition; and calculating affine transformation of living example of the object and a hierarchical relationship between the living examples during the splicing according to the position and dimension of the template in the layout, so as to carry out living example drawing to realize the synthesis of the printed pattern.

Description

technical field [0001] The invention relates to a printing pattern generation method, which belongs to the technical field of computer-aided design, in particular to a printing pattern generation method based on repeated pattern discovery. Background technique [0002] With the rapid development of the textile printing and dyeing industry, buyers and users have more and more diversified demands on printing patterns, the popular cycle of printing and dyeing products is getting shorter and shorter, printing patterns are changing faster and faster, and the importance of printing pattern design is becoming more and more important. higher. At present, through digital printing technology, the textile printing and dyeing industry can realize the printing and dyeing of small batches of printing patterns customized by users, which not only reduces the threshold for ordering batches, but also gives users the feasibility of creating printing patterns by themselves. However, the intent...
