基于LAB颜色距离的共生矩阵的纹理特征提取

The Extraction of Texture Based on the Co-occurrence Matrix of LAB Color-Difference

针对光照对成像的影响,采用均值滤波抑制噪声对图像的干扰,从而达到减弱光照影响的目的.在此基础上,介绍了一种基于LAB颜色距离的共生矩阵提取颜色-纹理特征的图像分析方法.在灰度共生矩阵方法的基础上,发展出LAB颜色距离的共生矩阵方法,解决了灰度共生矩阵方法不能有效处理彩色图像的缺陷,并从LAB颜色距离的共生矩阵中提取颜色和纹理特征用于图像分析.该方法易于实现,且具有较好的检测效果.

To reduce the influence of illumination, mean filter was used to weaken the influence of the noise on the image. Then, the method of studying the image was presented, based on the co-occurrence matrix of LAB color- difference a new conception which was proposed on the basis of gray level co-occurrence matrix. Both color and texture features were extracted from the co-occurrence matrix of LAB color-difference. The experimental results show that the method fits closely with human perception.
