I would like to know if there are any algorithms in ITK which would allow me to interpolate linearily missing pixels of a 2D image data (preferably with a CUDA implementation)?
To detail a little more my question, I have an image which looks something like the following :
0 0 0 0 0 0 ma 0 ma 0 0 ma ma 0 0 0 0 0 0 0
I want to linearly interpolate the pixel values at the masked coordinates using the surrounding unmasked pixels.
In python, using SciPy, the equivalent code would be something like this :
slice_2d[masked_pos] = griddata(unmasked_pos, slice_2d[unmasked_pos], masked_pos, method="linear")
Thanks in advance,
