Abstract: Traditional seed filling algorithm needs a great deal of time and space for a large of I/O stack operations.In order to avoid these shortcomings completely，this algorithm adopts new view.The experiment filled 100 oil region images indicates that the algorithm can completely fill region with a success rate of 100 percent，regardless of the shape，the size and the location.Compared with other filling algorithms，the algorithm has many advantages，such as simple processes，high computing speed，accurate and reliable.So it is a worthy promotion algorithm.
