Abstract:
提出了局部纹理统计模型与改进的Log-likelihood统计相结合的纹理图像检索方法。首先设计了3种不同角度分辨率和空间分辨率的“Uniform”模式的局部二值模式,并且用其来提取图像特征,然后建立图像局部二值模式和局部方差的联合统计模型,最后用改进的Log-likelihood统计进行图像检索。提出的基于局部纹理统计模型的纹理图像检索算法具有旋转不变性,克服了LBP算法对旋转比较敏感的缺点。通过对Brodatz图像库中50类600幅纹理图像进行仿真试验,新算法能得到89.71%的平均查准率,与基于Gabor小波+WMV组合算法相比,新提出算法的查准率提高了19.05%。
