[Insight-users] Submission: PCA decomposition calculator

[Lorensen, William E (Research)]

Luis and Zach,

I fixed the problems with this test yesterday. It is now passing everywhere.
If you make changes to the code or test, please edit the current cvs
repository versions.

Thanks,

Bill

Hi Zach,

Thanks for looking into this.

Unfortunately I just tried the new test along
with the new .h and .txx files that you sent
and the test is still failing.


Here is the output I got:

-----------------------------------------------------------------

ImagePCADecompositionCalculator (015E6220)
   RTTI typeinfo:   class itk::ImagePCADecompositionCalculator<class 
itk::Image<double,2>,class itk::Image<double,2> >
Test failed  Reference Count: 1
   Modified Time: 25
   Debug: Off
   Observers:
     none
   Projection: 0.6228 -2.9346
   Image: 015E6008
The basis of projection is:
[-0.3853 0.5929 0.5929 -0.3853 ]
[-0.5929 -0.3853 -0.3853 -0.5929 ]
The projection of [0 2 2 0] is [-1.5412 -2.3716]
this should be approx [-1.5412 -2.3716]
The projection of [0 3 3 0] is [0.6228 -2.9346]
this should be approx [3.5574 -2.3119]


The project is out of the range of Matlab precomputed values
***Failed
