ITK Bug Fixes

Implement a filter that takes N images as input and produces a Image of Vectors as output.
Implement a Quadratic Polynomial Transform in ND: it will have N^3 coefficients.
Implement a filter for converting RGB images into HSV and its complementary filter from HSV to RGB.
Add test for basic FFT filtering tasks (impulse input, step input), verify direct+inverse transformation
Create a debugging helper class that will compute the total value of memory allocated by images. (to be used from the image->Allocate() method)

Create an ITK+VTK class that uses the vtkPointWidget for providing seed indexes to ITK segmentation methods.
Create an ITK+VTK class that uses the vtkAffineWidget.cxx in order to initialize an ITK Affine transform for image registration.
Create an ITK+VTK class that observes an ITK registration and every N iterations shows the relative overlapping position of the images in a VTK scene
Create an ITK+VTK class that observes an ITK LevelSet segmentation method an every N iterations uses the vtkContour filter to show the current position of the zero set overlapped to the input image.
Create an ITK+VTK class that visualize the vector displacements of a BSplineDeformableTransform, Connected as an observer to an ITK optimizer it will be able to visualize the progress of a deformable registration. (Vectors will be visualized using glyphs)

The VTK widgets are missing tests. Please choose any five (5) .cxx exmaples and add a test for each.
Create an analogous class to vtkAxisActor2D, except in 3D (i.e., vtkAxisActor3D).
Implement a variation of vtkHeap that recovers memory.
Commit three classes into VTK. These are classes have been written in a branch, and are ready to be added to VTK. In some cases the classes already have tests. They need committing and dashboard watching.
Given a initial implementation of vtkPieChartActor, vtkBarChartActor and vtkSpiderPloyActor, rework any one of them to obtain proper layout in the specified rectangle. (Note: Dr. Schroeder will provide the initial implementation.)
Answer any five (5) questions on the VTK users or VTK developers mailing list
