Circles
We can extend the Hough transform to other shapes that can be expressed parametrically. For example, a circle of
fixed radius can be described fully by the location of its center (x, y).
Think of each feature (edge) point on the circle as saying, ”if I’m on the circle, the center must be in one of these
places”. It turns out that the locus of these votes is itself a circle.
But what about circles of unknown size? In this case, we need a third parameter: the radius of the circle. So, we can
parameterize circles of arbitrary size by (x, y, r). Instead of casting votes in a circular pattern into a two-dimensional
accumulator, we cast votes in circles of successively larger size in a three-dimensional accumulator.

In BayesShrink[5] we determine the threshold for
each subband assuming a Generalized Gaussian
Distribution(GGD) . The GGD is given by
GG¾ X ¯ (x) = C(¾ X ¯ )exp¡ [® (¾ X ¯ )jxj]¯ (6)
¡ 1 < x < 1 ¯ > 0, where
® (¾ X ¯ ) = ¾ ¡ 1
X [ ¡ (3=¯ )
¡ (1=¯ ) ]1=2
and
C(¾ X ¯ ) = ¯ ¢ ® (¾ X ¯ )
2¡ ( 1
¯ )
and ¡ (t) =
R1
0 e¡ uut¡ 1du.
The parameter ¾ X is the standard deviation and ¯
is the shape parameter It has been observed[5] that
with a shape parameter ¯ ranging from 0.5 to 1, we
can describe the the distribution of coefficients in a
subband for a large set of natural images.Assuming
such a distribution for the wavelet coefficients, we empirically
estimate ¯ and ¾ X for each subband and try
to find the threshold T which minimizes the Bayesian
Risk, i.e, the expected value of the mean square error.
