代码说明:

在DCT域考虑自然图像的统计特征(非高斯特性),把图像分割成不同的块统计其自然特性,提取不同方向子带,频率子带的变异系数特征,形状参数特征,通过回归学习的方法评估图像的质量。

    假设检验例题 7.1 设总体 ,其中参数 , 为未知,试指出下面统计假设中哪些是简单假设,哪些是复合假设: (1) ; (2) ; (3) ; (4) ; (5) . 解:(1)是简单假设,其余位复合假设 (Hypothesis testing for Example 7.1 overall, including parameters, is unknown, pointed out that the following statistical hypothesis test which is a simple assumption, which is a compound hypothesis: (1) (2) (3) (4) (5). Solution : (1) is a simple assumption, the remaining bit composite hypothesis)
