... smoothstyle =`adaptive'. This is exactly the same as the patchwork convolution described in section 3.3.4 , except here the task calculates the library of convolvers and the associated index image itself. ... The task actually makes two passes through the library of gaussians: the first as described above, to calculate the index image; the second refers to the index image while performing the convolution, exactly as described in section 3.3.4 . ...
