摘要： 针对番茄缺素病叶片图像的特征提取问题,提出了不受对象形状、大小影响的彩色图像颜色和纹理特征提取的几种统计算法和图像数据间的相关系数法,其中纹理特征的提取是把图像的数据经傅立叶变换到频域中进行特征提取的。经实验验证,这些彩色图像颜色和纹理特征的提取方法对番茄缺素病的判别是较理想的。

Abstract: In this paper, several methods of color and texture extracting of color image are put forward. Their effects are not changed with the change of the objects shape and size. The methods include statistical algorithms and an algorithm of the correlation coefficient between two matrices of the same size. The way of Fouliers transform is applied in extracting the color images texture feature. The experiment results of extracting color and texture of the tomatos leave color images prove that the methods are effective.
