In that blog I see it mentions the kawase blur and downscaling, but this is a different method.<br />
While that in the blog downscales, blurs the image and then upscales, this method here combines the two so it only downscales and upscales.<br />
You can read more info and performance comparison about the dual kawase blur (starts at page 21):<br />
