Embodiment Construction

[0038] Please refer to the attached figure 1 to attach Figure 7 Shown, the present invention is a kind of fabric printing cycle pattern primitive segmentation method based on self-adaptive template matching, and it comprises following several steps:

[0039] (1) Adaptive template selection: automatically determine a template image with an adaptive size in an image containing a printing cycle pattern;

[0040] (2) Template matching: use the template pattern in step (1) as a template, carry out template matching with the original image, and find the region similar to the template pattern in the original image;

[0041] (3) cycle size determination: according to the positional relationship between the regions similar to the template pattern found in step (2), determine the size of the pattern cycle;

[0042] (4) Cyclic pattern primitive segmentation: According to the loop size determined in step (3), the original image is traversed to segment a complete pattern primitive that ...

Abstract

The invention relates to a segmentation method of fabric printing cycle pattern primitives based on adaptive template matching, comprising the following steps: 1. the adaptive template selection: automatically determining an adaptive size template image in an image containing the printing cycle pattern; 2. template matching: template pattern in the step 1 is the most template, template matching iscarried out with the original image, and regions similar to the template pattern in the original image are found; 3, determining the size of the cycle: determining the size of the pattern cycle according to the positional relationship between the regions similar to the template pattern found in the step 2; 4. cyclic pattern primitive segmentation: according to the cyclic size determined in step (3), the original image is traversed and a complete pattern primitive conforming to human visual perception is segmented. The invention can automatically segment a complete pattern primitive from an image with a circulating pattern, avoids the shortcomings of slow manual segmentation speed, low efficiency and poor segmentation precision, and accelerates the flow of printing pattern development anddesign.

Description

【Technical field】 [0001] The invention relates to a method for segmenting fabric printing cycle pattern primitives based on adaptive template matching, so that a complete pattern can be automatically segmented from the printing fabric cycle pattern, and belongs to the technical field of digital image processing. 【Background technique】 [0002] Repetition is an important feature of printed fabric patterns, and most of the printed patterns on the market now have this feature. Now when most printing factories make printing patterns, they first scan the sample fabrics with cyclic patterns brought by customers into digital images; then use drawing software to manually intercept a minimum pattern cyclic base Then the designer draws the intercepted pattern cyclic primitives into a high-definition pattern suitable for plate making in the drawing software; finally, according to the customer's requirements, the drawn high-definition cyclic pattern primitives are combined into the cust...
