【摘要】 基于非对称逆布局模式表示模型,提出了一种多边形子模式的非对称逆布局的图像表示方法(NAIRP).该方法用多边形作为子模式进行最大化非对称分割,给出了该方法的具体算法步骤和子模式的存储结构,对数据量和算法的时空复杂度进行了理论分析.实验表明:在保证图像质量的前提下,与流行的4元树方法相比,NAIRP方法在子模式数量和数据存储量上具有明显的优势.更多还原

【Abstract】 On the basis of non-symmetry and anti-packing pattern representation model,a method to represent non-symmetry and anti-packing images by polygon sub-pattern(NAIP) is proposed.The approach maximize the nonsymmetry partition using polygon sub-pattern.The encoding and decoding algorithms is presented,after giving encoding and decoding algorithms,the paper analysed the time and space complexity.Theoretical analysis of the data amounts and the experiments show that the approach is greatly superior to linear quadtree in the aspects of data amounts and sub-pattern′s quantities on the premise of remaining the image quality.更多还原
