Equivalent to : img.genConvSeparated( parabola, "add", "minAssign", HxImageRep::ARITH_PREC)

where parabola is the 1d double-precision parabolic kernel based on rho and accuracy.

Notice that the kernel is applied to every dimension of the image separately and that the result image has a double-precision pixel type.
