Objective

We have started the Non-rigid Image Registration Evaluation Project (NIREP) to develop software tools and provide shared image validation databases for rigorous testing of non-rigid image registration algorithms. NIREP will extend the scope of prior validation projects by developing evaluation criteria and metrics using large image populations, using richly annotated image databases, using computer simulated data, and increasing the number and types of evaluation criteria.

Approach, Plan

The goal of this project is to establish, maintain, and endorse a standardized set of relevant benchmarks and metrics for performance evaluation of nonrigid image registration algorithms. Furthermore, these standards will be incorporated into an exportable computer program to automatically evaluate the registration accuracy of nonrigid image registration algorithms.

Our goal for this week is to further the prototype software package that was created last year with help in these areas:

• Learn the best way to break the VTK & ITK pipelines
• Implement streaming of images in NIREP software
• Learn how other tools combine images, landmarks, contours, surfaces, etc. into a composite image.
• Discuss design of the Database Manager and investigate how database managers are implemented in other tools.
• Use CPack to package the NIREP program.
• Setup and use a DART Dashboard at Iowa
• Investigate integration of wxWidgets with ITK and VTK.
