摘要
为了更好地描述图像的纹理特征,定义了灰度—基元共生矩阵。该矩阵将描述纹理特征的统计方法和结构方法结合起来,描述图像的灰度分布情况,具有一定的旋转不变性。为了减少共生矩阵的计算量,采用了正规化处理方法。
In order to describe the image texture feature more exactly, it introduces a gray-primitive co-matrix. The matrix can combine statistical methods with structural ones naturally, which can be used to describe the gray distribution and the local detail structure in a textured image. The matrix has rotation-invariance. In order to reduce calculation of co-matrix a normalization to the matrix is used.
