Reversible Image Authentication Based on Difference Expansion and Error Correction Code 基于差值扩展和纠错编码的可逆图像认证
A novel construction algorithm for symmetrical Reversible Variable Length Codes ( RVLC) is proposed based on the analysis of the symmetrical RVLC code tree, which is independent of the Huffman code. 在分析对称可逆变长码码树结构的基础上,提出了一种独立于Huffman码的对称可逆变长码构造算法。
A Novel Symmetrical Reversible Variable-length Code Based on Cost-evaluating 一种新型的可逆变长码&代价测评对称可逆变长码
By means of the fact of certain reversible cyclic codes, two sufficient conditions for the minimum distance of a cyclic code to equal its BCH bound have been found. Some Results on Bounded BCH-algebras ( I) 利用一类自反循环码的事实,证明了使循环码的极小距离等于其BCH界的两个充分条件;关于有界BCH-代数的一些结果(Ⅰ)
