摘　　要：纬编提花像景织物由于织物结构及织造工艺条件限制,只能使用少量颜色。为了将数字图像自动转换为纬编提花图案,减少细节损失,文章将图像从RGB空间转换到HSV空间,通过最大类间方差法将图像色相量化到2~3个,然后利用映射模板将2~3个不同的色调与纯黑和纯白结合,替换图像中不同的饱和度和亮度,呈现出原始图像中的不同颜色。最终生成仅包含2~3个颜色和黑、白两色的数字图像作为纬编伪彩色针织像景织物的花型意匠图,且其中的颜色数为4~5个,适合作为纬编提花意匠图。Weft knitted jacquard pattern can only include a few colors due to the limitations of fabric structure and knitting process conditions.For the purpose of transforming digital images into weft knitted jacquard patterns automatically with less detail losing,in this paper,the image was transferred from RGB space into HSV space,the hues of the image were quantified to 2-3 through maximum between-cluster variance method,and then the different saturations and values in the image were replaced by a mapping template,which was used to combine the 2 or 3 different hues with pure black and pure white to present variant colors in original image.Finally,a drafted notation for weft kntted jacquard fabric with pseudocolor image was generated,which contained only 2-3 different hues'colors and black and white,so the number of colors in the pattern will be 4-5,which is suitable as weft knitted jacquard pattern.
