In order to solve the edge discontinuity produced by the edgeflow method used to detect the image edge, the edgeflow was made a variable into the level set equation and a multi-scale idea was also introduced into it. First, arough contour was found out by the way that the edgeflow vector, being acquired through the image with large scale, and it was put into the level set equation; Second, the rough contour was gradually optimized as an initial one in another level set equation of smaller scale when its edgeflow vector was calculated out and put into level equation to solve; Finally, the segmentation of image was carried out. The results showed that it eliminates the edge discontinuity and speeds up the curve evolution when applied to the segentation of conglomerate image.
