基于彩色图像处理的生丝截面特征参数提取

 通过将生丝包埋切片图像由RGB空间转化到HSI颜色空间,基于HSI颜色模型将具有某种色彩信息的生丝截面从背景图片中分离出来,并转化为灰度图像。利用边缘检测的方法,将生丝截面部分转化为二值图像,然后再根据所提取生丝部分的形状、大小等特征,利用图像膨胀和腐蚀的方法对二值生丝截面图像进行处理,从而得到完整的生丝截面图像,最后通过图像矩阵处理的方法得到评价生丝截面的特征参数。结果表明,该方法可以较准确地得到生丝截面的特征参数。

Characteristic parameters extraction of raw silk's cross-section based on color image processing

The raw silk embedding slice was changed to HSI color model from RGB color model,after that the raw silk′s cross-section with some color was extracted from the background image based on HSI color model,and the processed color image was changed to gray image.The image of raw silk′s cross-section was turned to binary image through edge detecting,then the binary image of raw silk′s cross section was processed with image dilation and erosion after analyzing the shape and the size of it,and the whole raw silk′s cross-section was got.Finally the characteristic parameters of raw silk′s cross-section were gained by using the image matrix processing.The results indicted that this method can gain the characteristic parameters of raw silk′s cross-section exactly.
