N4Explorer: preparatory work with APIs so the optimizations structures and code of the BiCalExplorer could be fitted without any change.

Saturday, May 28, 2016

BiCal run on 4 volumes:

80 positions per volume were estimated. Total execution is 7+ hours.  We varied the smoothing power [0,100] and the polynomial degree [6,13].







"Class separation measure":  was reduced from the original  0.173 down to 0.003











Resulting optimal BiCal parameters are:

BiCal explorer:  completely implemented including the specialized Dialog box.
This optimization works for a single volume at the moment.

FireVoxel Build 216B is released.
N4-UI function:  since the output is real, added the REAL->INT postprocessing conversion to match the Source volume type.
Implemented the "Misclassification of the Optimial Separation" function and the User Interface under "MainMenu>Nonuniformity". Function is fully parallel and executes very fast.

"MainMenu>Measurement>Hausdorff Distance":
Implemented the Hausdorff distance measure {Edge,Area} variants.

Build 216 is released.

  • RasterPaintbrush  Tool\Dialog:  fixed the defect when the SmartZoom option setting was not remembered.
  • N4-tool:  implemented the option Output field.
  • N4 dialog box:  replace the "Field Smoothness" name with the "Spline Distance" to emphasize difference with the NYU-N3 tool between those 2 terms.
  • N3-NYU tool:  fixed the crash for large values of the "Field Smoothness" = 200.
  • N4 crash defect, with supplied parameters (iter=75): fixed.
  • Non-Uniformity Measurement:  fixed a defect that exactly two ROI layers are required for the measurement.
  • Now any number of ROIs might be present, as long as only two are ENABLED.
  • Non-Uniformity measurement:  implemented function and Menu Item to measure 2 sets of blobs that are not completely paired.  This allows to measure non-uniformity more completely, while using the paired blobs for constraints.

FireVoxel Build 215 is released.
Non-uniformity\Two tissue Contrast measurement:  improved diagnostics when there is no full blob pairing between the tissues.
Finished the integration of the N4 bias correction binary tool.  This includes the new N4 dialog box:

NIFTI-1 file format (.NII):  implemented Save (UI) for the integer volumes.
