Objective: To explore a potential non-rigid collaboration between Gary Christensen's Group and NA-MIC.
Progress:
Next Steps:
- a discussion before project week
- meet as a group at project week
- explore collaboration grant

Project background:
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.
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.

Tasks to accomplish
- Build a prototype software package that contains the following functionality
- Database manager that interfaces with the evaluation database, the database of transformations for each algorithm, stores generated results, manages loading of images, manages memory, expands transformations from coefficient files, handles requests from other NIREP components, keeps track of operations using an XML (MRML) description,
- Display manager is responsible for displaying images, landmarks, contours, surfaces, and associated semantic information. It also displays metric information in various formats. The display is described in an XML (MRML) description
- Evaluator is responsible for all the computational aspects of image manipulation and computing metrics
- Application interface is a basic menu system for invoking and configuring the display manager and evaluator.
