摘　　要：建立一种单色织物数字图像中提取有效像素点的方法来表征该块织物的表面颜色。利用基于Sobel算子的梯度彩色图像边缘检测,去除表示纱线空隙的像素点;定义基于HIS颜色空间的像素奇异点,去除该点。将两种方法去除后剩下的像素点颜色信息作为布面的有效颜色信息,从而得到表示该布面颜色的RGB值。对180幅织物进行操作,查看布面图像的处理效果。最后比较两种织物数字图像表面颜色表征方法———将8幅图像所有像素点颜色信息作为有效信息,与将本方法得到的像素点颜色信息作为有效信息,计算得到RGB值。对织物表面颜色数字图像表征方法进行了简单讨论。This paper proposed to represent monochromatic fabric surface color through a digital image method. Edge detection gradient based on Sobel operator was used to delete the pixels representing the fiber gaps. The pixel singular point was defined in the HST color space, and was deleted from the image. The pixels that were not deleted by the two methods would be regarded as the valid color information of the fabric to get the RGB value of the fabric. 180 pieces of fabrics were treated by use of the digital image method to see the image and to calculate RGB value of all the pixels and the average value of the valid pixels, with fabric surface colour representation by digital image method briefly discussed.
