摘要: 羊毛衫织物组织的密度识别目前还未有成熟算法。本文就此展开研究,提出了一套基于极值簇的密度自动识别方法。首先计算任意识别区域的实际尺寸,采用线性方法对图像进行增强处理;进一步提出极值簇融合算法,抽取图像中线圈圈柱及空隙部分产生的灰度峰值簇及谷值簇,并将同一位置的同类极值簇融合,以绘制能显现图像变化规律的横向及纵向灰度极值簇融合图;最后给出了通过灰度极值簇融合图计算羊毛衫织物组织横纵密的公式。通过MATLAB7.0编程验证本文算法,得出其对纯色平纹、罗纹组织识别准确率大于98%的结论。

Abstract: here is not a mature algorithm for density recognition of sweater texture at present. This paper carries out reseach with this problem, and an automatic recognition method based on extreme cluster is proposed. Firstly, actual size of any recognition areas is calculated, image is made enhancement processing with linear method. Then a fusion algorithm of extreme is proposed. With this algorithm, gray peak cluster and valley cluster generated by loop column and void part in image are extracted, same extreme clusters in same position are fused, and fusion graph of gray extreme cluster for image change law is drew. Finially, calculation formula of lateral and longitudinal density of sweater texture is given. The algorithm in this paper is verificated by Matlab 7.0 and result is concluded that recognition accuracy is more than 98% for jersey and rib texture.
