# Each element is [sigma, sigma_name, radius].
# opencv's default width is calculated as:
#   cvRound(sigma1 * (depth == CV_8U ? 3 : 4) * 2 + 1) | 1
# Pulling that in helps a lot with making it faster (less data to read, and less
# math to do), but if you make it too narrow SIFT quickly freaks out.
