| 摘 要： | 对Contourlet变换构造以及Contourlet变换进行了描述,对其子带系数采用广义高斯模型进行建模.同时为进一步降低模型的计算复杂度,对模型进行曲线拟合.用两个变量描述每一系数模型概率.从而提取图像特征.最后,通过在Brodatz纹理数据库中图像搜索验证特征提取的有效性.

| Abstract: | After describing the Contourlet contribution and transform, using the Generalized Gaussian Model(GGD) to describe the coefficient of the image after the transform.For reducing the complicacy of the model, simulates the model by curve.Using two of variable in each coefficient, it can be used for feature extraction.Finally, uses experiment in the Brodatz texture image database to validate the model. |
