Improved Region Growing Method Based on "A Similar Points is Responsible for a Zone" and Its Applications
相似点区段负责制的改进区域生长法及其应用

Region growing algorithm is widely used in segmentation of special objects, but the slowly growing speed limits its application in certain area. In this issue, a new method is proposed to improve efficiency of Region growing. This method is based on a mechanism that a certain level zone is described by a single similar point. Only a region with many interior holes can be obtained with this method. Combined with Chain-code edge tracking algorithm, these interior holes can be filled completely and finally get regional compensation. With these two methods, an efficiency application system is established to analyze ceils of chain-like algae.
