Member ImagePyramid< VoxelType >::GenerateLevels (const nifti_image *const imageIn, unsigned int numberOfLevels, unsigned int numberOfLevelsToPerform, unsigned int minNumberOfVoxelsPerDim=1, float(*minVoxDim)[3]=nullptr)
Need to find a solution if slope is zero. If this is the case, the input data will be blacked out.
