Realization of Automatic Marking Edge in Jacquard Sample Drawing
Zhuge Zhen-rong · Advanced materials research · 2006
In the digital sweep bitmap of jacquard sample,when the mouse moves along the vision edge of pattern in the image,the color of pixel points near the moving track of mouse turns from RGB color space to YIQ color space,and the maximum gradation points of pixel in the detecting region of Sobel operator form the outline of objective pattern,connecting the obove points by straight segment,to realize the automatic marking edge.The results show that this project can mark the pattern edge quickly and efficiently,shortening the sample-drawing cycle,which is practical.
