BessDerivZerosBisect2
计算了贝塞尔函数的一阶导数的零点。
更新BessDerivZerosBisect.m这些变化:
1。允许对m= 0
2。允许用户指定特定的m和k值理想。
3。允许公差输入参数
4。使用一个表的查找能为m和k的小值接近初始化
5。添加错误检查
6。计算衍生w.r.t.以X而不是w.r.t.米(虽然老方法的工作也。)(Calculates the zeros of the first derivatives of Bessel function.
Updates BessDerivZerosBisect.m with these changes:
1. Allows for m = 0
2. Allow the user to specify the particular m and k values desired.
3. Allows for a tolerance input parameter
4. Uses a table look-up to get closer initializations for small values of m and k.
5. Adds error checking
6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

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.
