摘要：

为解决黑白单层提花织物对特定明度基调图像的灰度仿真设计问题,提出一种采用聚集态网点进行图像处理的提花织物设计方法。以3幅不同明度基调的图像为仿真对象,采用6种图像加网线数和2种织物间丝方法,进行聚集态网点结构提花织物样品的设计与织造。对原图像与提花织物图像的颜色特征进行比较与分析,结果表明:高、中、低3种明度基调图像分别适合采用24、14、10线/cm 3种加网线数;局部间丝方法可以提升网点织物图像的明度对比度;与影光组织提花织物图像相比,网点结构提花织物图像在灰度均值和方差2方面均较前者更接近原图,证明其具有更为稳定的灰度仿真性能。

Abstract:

In order to determine the grayscaling for black and white single-layer jacquard fabric in simulation with specific brightness tone image, a design method using the cluster-dotted method for image processing was proposed. Adopting three different brightness tone images as the simulation objects, the jacquard fabric samples were produced based on six screen frequency parameters and two float binding methods. According to the comparative analysis of the color characteristics of the original images and the figured fabrics, the results show that the high, medium and low brightness toned images are suitable for the ruling number of halftone screen that are 24, 14 and 10 lines/cm, and the local float blinding method can improve the lightness contrast of the fabric image with the cluster-dotted structure. In both mean and variance of the gray values,the cluster-dotted jacquard fabric images are closer to the original images than the shaded weave fabric images, demonstrating more stable grayscale simulation performance.

Key words: cluster-dotted, jacquard fabric, grayscale simulation, color feature, gray mean, fabric image
