Functions implementing a Gaussian pyramid approach.
This function down samples an image in the sense of a Gaussian pyramid.
It applies a Gaussian FixedFilterSize.Kernel5x5 to the image, then down samples the image by omitting every odd row and column, producing an output image whose size is halved in each dimension.
img | Image to be down sampled. |
ArgumentNullException | If the input img is null |

This function up samples an image in the sense of a Gaussian pyramid.
It inserts odd columns and rows filled with 0, then applies a Gaussian FixedFilterSize.Kernel5x5 multiplied by 4 to the image.
