Hello all,
a question about itkLinearInterpolateFunction, which is involved in
ResampleImageFilter. I have a segmented image with a white object(pixel
value=255) lies in black background(pixel value=0). If i transform it using e.g
translation or rotation, and resample it into a new file, then i get an image,
that seems to be OK. but i 've found, within this white object some pixes value
are not 255 but 254. This error leads to some artefacts in my subseuquent work.
I guess, the problem might consist in itkLinearInterpolateFunction. Can any one
tell me, what wrong with it?
By the way ,I tried the other two interpolatefunction BSpline und NN, but they
were worse.
thanks
Siwei
