Project Management
- ITK 3.6 on March 2008
Technical Topics
- .hdr/.img file format extensions map to 3 different interpretations in ITK. (Hans)
- What should the correct version be?
| IO that can write .hdr/.img files | Orientation | bytes in .hdr | Analyze^TM Program can read ITK written files correctly | ITK can read Analyze^TM written files correctly | Files tagged as nifti compliant |
|---|---|---|---|---|---|
| niftiImageIO (2 file nifti) | Quaternions | 352 | No | N/A | Yes |
| niftiImageIO ("Analyze") | SPM Style | 348 | Only if transverse orientation | Yes | Yes |
| AnalyzeImageIO | Mayo Clinic | 348 | Yes | Yes | No |
- Proposal:
- 1. Place AnalyzeIO before niftiIO in reading/writing order
- 2. Ensure that AnalyzeIO "CanRead" mechanism rejects files that are tagged as "Nifti Compliant"
- 3. niftiImageIO Add member function that turn on/off the ability to recognize ".hdr/.img" extensions as valid for writing (Only useful when niftiImageIO is explicitly specified for writing.). Add member function to specifify which "2 file .hdr/.img" form should be used for writing (2 file nifti or Analyze).
- 4. default niftiImageIO to not recognize ".hdr/.img" as valid for writing.
- Proposal:
- Improvements to MattesMutualInformation (Matt,Luis)
- Removing the JointPDFDerivatives array
- It used a 3D array of floats, of size : (Number of transform parameters) X (number of histogram bins)^2
- Removing the JointPDFDerivatives array
- Improving LevelSet filters to use image spacing (Luca)
- Dealing with fudge factor
Bug Triage
- Starting after: 4559
