An image segmentation method which combines Multi-scale Edgeflow and Ncut(Normalized cut) was put forward.First,Multi-scale Edgeflow was used to detect the edges existing in both largescale and small scale,edge position was made in small-scale,then a closed edge was acquired through a marginal connection.Second,the region acquired by Multi-scale Edgeflow was regarded as the vertices of the graph in Ncut;the similarity criterion among regions was regarded as elements of similarity matrix.Thus,the memory requ...
