  • Title: An efficient and generic extension to ITK to process arbitrary shaped regions of interest.
    Author: Fasquel JB, Agnus V, Lamy J.
    Journal: Comput Methods Programs Biomed; 2006 Jan; 81(1):1-7. PubMed ID: 16371240.
    Abstract:
    The paper describes a software method to extend ITK (Insight ToolKit, supported by the National Library of Medicine), leading to ITK++. This method, which is based on the extension of the iterator design pattern, allows the processing of regions of interest with arbitrary shapes, without modifying the existing ITK code. We experimentally evaluate this work by considering the practical case of the liver vessel segmentation from CT-scan images, where it is pertinent to constrain processings to the liver area. Experimental results clearly prove the interest of this work: for instance, the anisotropic filtering of this area is performed in only 16 s with our proposed solution, while it takes 52 s using the native ITK framework. A major advantage of this method is that only add-ons are performed: this facilitates the further evaluation of ITK++ while preserving the native ITK framework.
