Abstract: The traditional image segmentation method based on graph theory is based on pixel level, whose application is limited when pixel number gets larger. So an improved image segmentation algorithm is proposed, in which image pixels are aggregated to form a super pixel using the Dijkstra algorithm and the Kruskal algorithm is used to get minimum spanning tree, determine and delete the inconsistent minimum spanning tree, and complete image segmentation. The experimental results show that the improved algorithm has the characteristics of regional segmentation uniformity and good consistency.

Key words: graph theory, image segmentation, minimum spanning tree, shortest path, inconsistent side
