说明: 提出了一种基于数学形态学的多尺度熵权边缘检测方法。信息熵为图像的内在特性,由它来决定不同结构元
素所提取的边缘在最终合成边缘中所占的比重,是自适应的和客观的(A multi-scale based on mathematical morphology edge detection method of entropy. Information entropy inherent characteristics of the image, from which different structural elements to determine the edge of the extracted edge in the final synthesis of proportion, is adaptive and objective)

MyBayes
2.编写两类正态分布模式的贝叶斯分类程序。
设以下模式类别具有正态概率密度函数:
ω1:{(0 0)T, (2 0)T, (2 2)T, (0 2)T}
ω2:{(4 4)T, (6 4)T, (6 6)T, (4 6)T}
(1)设P(ω1)= P(ω2)=1/2,求这两类模式之间的贝叶斯判别界面的方程式。
(2)绘出判别界面。
3.已知服从正态分布的两类训练样本集分别为
:,,,,
:,,,
,试问属于哪一类?
4.设有两类一维模式,每一类都是正态分布,两类的均值和均方差分别为,;,。
采用(0-1)损失函数,且。
(1)试绘出两类模式的密度函数曲线,其判别界面位于何处?
(2)若已获得样本:-3,-2,1,3,5,试判断它们各属于哪一类。(bayes ,matlab)
