摘要
借助于颜色游程的概念,提出了一种基于游程矩阵的彩色图像特征描述方法,并在此基础上定义了两种图像相似性测度。为了增强图像特征描述的稳健性,对游程矩阵引进了累积变换。对真实图像检索的实验表明,本文的方法对于纹理图像的检索具有很好的检索效果。
According to the conception of color run-length, a method of feature representation based on run-length matrix for color image was proposed,then two similarity criterions were given.In order to enhance the robusticity in feature representing,the cumulative transformation was defined for run-length matrix.After experimented for true images, the better achievement is obtained when retrieving texture images by our approaches.
