the
canny
edge
detection
algorithm
is
known
to
many
as
the
optimal
edge
detector.canny边缘检测算法对很多人来说是众所周知的最佳边缘检测工具。
canny's
intentions
were
to
enhance
the
many
edge
detectors
already
out
at
the
time
he
started
his
work.canny的意图是提高很多在他开始自己的研究时就已过时的边缘检测工具。he
was
very
successful
in
achieving
his
goal
and
his
ideas
and
methods
can
be
found
in
his
paper,
"a
computational
approach
to
edge
detection".
他在实现自己的目标时非常成功，他的概念和方法可以在本文中看到。in
his
paper,
he
followed
a
list
of
criteria
to
improve
current
methods
of
edge
detection.
在本文中，他遵循了一系列的准则来改进边缘检测的现有方法。the
first
and
most
obvious
is
low
error
rate.首先而最明显的是低的差错率（误码率）。
it
is
important
that
edges
occuring
in
images
should
not
be
missed
and
that
there
be
no
responses
to
non-edges.
以下两点很重要，即发生在图像中的边缘不应被错过，以及对非边缘“没有”响应。the
second
criterion
is
that
the
edge
points
be
well
localized.这第二条准则是，边缘点被很好定位。
in
other
words,
the
distance
between
the
edge
pixels
as
found
by
the
detector
and
the
actual
edge
is
to
be
at
a
minimum.换句话说，由检测器发现的边缘像素和实际边缘之间的距离要处于最小值。
a
third
criterion
is
to
have
only
one
response
to
a
single
edge.第三个准则是对单一的边缘只有一个响应。
this
was
implemented
because
the
first
2
were
not
substantial
enough
to
completely
eliminate
the
possibility
of
multiple
responses
to
an
edge.这一条得到了实施，因为前两条对完全消除一个边缘可能出现多次响应方面还不够充分。
