代码说明:

1定义CBIR或基于内容的图像检索是基于视觉特征(如颜色、纹理和形状)的图像检索[2]。其发展的原因是,在许多大型图像数据库中,传统的图像索引方法已被证明是不够的,费时费力。这些旧的图像索引方法,从将图像存储在数据库中并将其与关键字或数字关联,到将其与分类描述关联,都已过时。这不是CBIR输入在CBIR中,存储在数据库中的每个图像都提取其特征,并与查询图像的特征进行比较。它包括两个步骤[3]:特征提取:第一步是将图像特征提取到一个可分辨的区域范围匹配:第二步涉及匹配这些特征以产生视觉相似的结果。1.2 CBIR的应用

    (书)现代通信系统使用MATLAB第四章(ALLIANCES is a recently proposed cooperative random access protocol for wireless networks. In this paper we modify the original model to include user location information. We also derive pair-wise error probability (PEP) under Rayleigh flat fading channel and a power-law attenuation environment. Based on the PEP analysis we propose an optimal relay selection scheme, which achieves significant throughput gains as compared to the random relay selection scheme in the original ALLIANCES.)
