A local threshold approach would require the setting of another scale parameter.
Even if the scale parameter is well-tuned, as the dimensionality of the problem increases, progress can still remain exceedingly slow.
Here 1 is a scale parameter related to the a priori distribution of the standard error.
The larger the scale parameter, the more spread out the distribution.
The gamma distribution is usually parameterized in terms of a scale parameter or its inverse.
Special cases of distributions where the scale parameter equals unity may be called "standard" under certain conditions.
A statistic can be used to estimate a scale parameter so long as it:
The scale parameter is called the blur scale of the edge.
The parameter is a scale parameter and is also the median of the distribution.
This makes it of special interest for use with scale parameters.
