The research on graphic outline capturing algorithm based on coloured embroidery pattern of HIS space

Computerized embroidery needs outline capturing of color images and stitch filling. Embroidery machines can make stitch filling according to color blocks in different areas. Considering the character of stitching of embroidery machines and referring to color image morphology, this thesis puts forward multi-scale graphic outline capturing algorithm based on color embroidery pattern of HIS space. And a variety of edge detection algorithms were compared. Experiment results show that this method can effectively control impact of noise on images. And the effect of image capturing can meet requirements of embroidery patterns.
