An Integration of Live Wire, Graph Cut and Oriented Active Appearance Model for Distinctive Bio-Organ Segmentation

C.Nagavani, T.Prathiba, R.Umamaheswari

A new novel method is proposed to segment an abdominal organ which is combining Live Wire (LW), Graph Cut (GC) and Active Appearance Models (AAM). This method consists of three main parts: 1) Model building, 2) Object recognition or initialization, and 3) Object delineation. In the first part, the AAM is constructed and estimated the LW cost function, GC parameters. In the second part, Oriented Active Appearance Model is proposed by combining the LW and AAM methods. The pose of the organs are segmented slice by slice by via OAAM method. In the third part, GC method is used to shape the image accurately. To further refinement of shaping, an iterative GCOAAM method is applied for object delineation. With GC-OAAM approach liver image is segmented in an abdominal organ.
