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。

Gabor-ring is often used in texture feature extraction, but it is based on the assumption that texture is narrowband signal and can not applied to most actual textured images that have more than one center frequency in power spectrum. To overcome the limitation of existing method, an improved method is proposed. According to this method, Gabor filters are constructed in accordance with the spectrum feature vector of texture, and a relaxation parameter is used to determine the effect of difference filters so as to integrate the frequencies and phases into the process of extraction.

Gabor环（即在频率域成环形分布的Gabor滤波器组）常被用于提取图像纹理特征，但它是以"纹理是窄带信号"为基础的，实际的纹理图像并不能很好地满足"窄带信号"的假设，用一个中心频率来描述一种纹理对能量集中在多个频率点的纹理图像往往不能取得理想的效果，而根据频谱特征值向量构造Gabor环的改进方法，通过松弛因子的加入改变不同滤波器的作用强度，综合考虑了多频率多相位对纹理特征提取的影响。

The feeding regimes, including optimum feeding frequency, diel feeding rhythm, and optimum feeding rate, were established for gibel carp . The optimum feeding frequency for gibel carp was determined through 8week growth trial at five frequencies (2, 3, 4, 12 and 24 meals/d). Diel feeding rhythm of gibel carp was investigated by 24-hour trials at two body sizes (mean body weight: 20.5g and 76. 3g). The optimum feeding rate for gibel carp was estimated by the bioenergetics modelling and the validation trial was carried out based on the the feeding regimes of gibel carp.

异育银鲫的最佳投喂频率是通过设计5组不同的频率2、3、4、12及24次//天，经8周生长实验，然后比较鱼体生长和饲料转化效率获得的；异育银鲫的日摄食节律是通过对两组不同体重异育银鲫（平均体重20.5g和76.3g）24h内摄食率的测定而获得的；异育银鲫的最适摄食率是通过鱼类生物能量学模型的建立而获得的；最后通过生长实验对建立起来的异育银鲫投喂体系进行了验证。
