float CxImage::KernelGaussian (  const float  x  )  [static, inherited]
 

float CxImage::KernelGeneralizedCubic (  const float  t,
const float  a = -1
)  [static, inherited]
 

Bicubic kernel (for a=-1 it is the same as BicubicKernel): 

          /
         | (a+2)|t|**3 - (a+3)|t|**2 + 1     , |t| <= 1
  h(t) = | a|t|**3 - 5a|t|**2 + 8a|t| - 4a   , 1 < |t| <= 2
         | 0                                 , otherwise
          \
Often used values for a are -1 and -1/2.
