Embodiment

[0046] The present invention comprises the following steps:

[0047] Step 1: Obtain the image of the dyed fabric;

[0048] Step 2: convert the color-dyed fabric image from RGB color space to HSV color space and Lab color space respectively;

[0049] Step 3: Extract global color features and local texture descriptors of the mixed color space; including the following sub-steps:

[0050] Step 3.1: The global color feature extraction adopts the color aggregation vector method, which can not only effectively represent the color information, but also contain the spatial information of the color distribution. The color aggregation vector of the image is expressed as follows:

[0051] f=1 ,β 1 ),(α 2 ,β 2 ),…(α i ,β i )> Formula 3.1

[0052] In the formula, α i is the aggregation number of the i-th cluster, β i is the non-aggregate number of the i-th cluster, (α i ,β i ) is the ith aggregation vector pair;

[0053] Calculate the color aggregation vector f of the H componen...

Abstract

The invention belongs to the technical field of image processing, and relates to a colored textile fabric color difference degree detection method which is widely applied to the fields of artificial intelligence, color analysis, pattern recognition, intelligent detection and the like. According to the method, color space conversion is firstly carried out on an image, then global color features andlocal texture descriptors are extracted from HSV and Lab color spaces respectively, and finally corresponding features are fused to obtain mixed color space color representation features. According to the method, the defect that colors are described in a single color space is overcome, the color depicting capacity of the mixed color space is improved, the color difference degree is accurately detected, and the method has universality for different colored spun fabrics.

Description

technical field [0001] The invention relates to a method for detecting color difference of colored textiles, which belongs to the technical field of image processing. The established color characterization feature of mixed color space can effectively represent the color of colored textiles and further detect the color difference. Background technique [0002] Color-spun fabrics are made of two or more different dyed fibers mixed and spun through a specific process, which has a special color rendering effect. By adjusting the ratio of dyed fibers and the production process, color-spun fabrics with rich color levels can be obtained. In the production process of color-spun fabrics, it is difficult for enterprises to detect the target color, so scientific color characterization is needed to accurately detect the color difference between different colored fabrics. [0003] The commonly used color spaces have limitations in the representation of complex color models, and cannot ac...
