Abstract
Gaussian convolution is one of the most important algorithms in image
processing. The present work focuses on the computation of the Gaussian
scale-space, a family of increasingly blurred images, responsible, among
other things, for the scale-invariance of SIFT, a popular image matching
algorithm. We discuss and numerically analyze the precision of three
different alternatives for defining a discrete counterpart to the
continuous Gaussian operator. This study is focused on low blur levels,
that are crucial for the scale-space accuracy.
