entire pyramid.
- The procedure above was useful to downsample an image. What if we want to make it bigger?:
columns filled with zeros (\f$0 \f$)
- - First, upsize the image to twice the original in each dimension, wit the new even rows and
+ - First, upsize the image to twice the original in each dimension, with the new even rows and
- Perform a convolution with the same kernel shown above (multiplied by 4) to approximate the
values of the "missing pixels"
- These two procedures (downsampling and upsampling as explained above) are implemented by the
