The ADWM filter has the features of directional filter, which is especially effective at preserving edges, and the features of center weighted median filter, which can reduce random noise, and moderate amounts of impulsive noise also, to some extent, as well as preserve the details via adaptively determining the weight of the center pixel according to the lowest variance of pixels within all the sub-windows.

ADWM滤波器既有定向滤波器的特征，也有中心加权中值滤波器的特征。定向滤波器可以有效保持边缘，而中心加权中值滤波器对减少随机噪声尤其有效，同时也能在一定程度上减少冲击噪声的数量，并根据子窗口内像素的最低方差自适应地调整中心像素的权值以保持图像的细节。

Results: No statistic significant differences between children sex and receiving or non-receiving this benefit factor, however, significant difference were showed at medical providing territories and insured fee factor pConclusions: In the selected children, parent's decision making and territory variance (ex: cities vs. townships gave influence of children to receive teeth fluoridation and incidence rate of caries.

研究结果发现，儿童接受涂氟与否与性别无统计差异；但与就医地区别、全民健保投保金额组别呈现统计上显著差异p依本研究显见涂氟可减少健保牙科医疗利用，确可达到降低医疗费用支出的目的，惟其所减少之健保医疗费用支出，尚未符合公务支付涂氟成本之效益。

A set of complex Morlet wavelet are applied on projection slice of each direction to decompose each projection into several frequency channels,the average and variance extracted are computed in each frequency channel,and then linear regression model is employed to computer realationship feature between frequency channels.1-D DFT is applied to features and the amplitudes of Fourier coefficient are selected as features,then the extracted features are rotation invariant.

该算法是将一定大小的图像进行二维傅里叶变换；其次在变换后的图像中央选择一个圆盘区域，并在方向［0°，180°］内进行等间隔角度频率抽样，实现方向分解，使用一组复Morlet小波对每个方向上的映射切片进行小波变换，从而实现多通道频率分解；在各个频率通道中计算均值和方差作为特征，并利用线性回归模型计算频率通道之间的关系特征；将特征沿方向进行一维傅里叶变换并取其幅值，从而得到旋转不变性特征。
