求翻译:In matrix embedding (ME)-based steganography, the host coefficients are minimally perturbed such that the transmitted bits fall in a coset of a linear code, with the syndrome conveying the hidden bits. The corresponding embedding distortion and vulnerability to steganalysis are significantly less than that of conventio是什么意思? 待解决

(我)为基础的矩阵嵌入隐秘,主机系数最小扰动传输的比特下跌,在一个线性码的陪集,输送综合征隐藏位。相应的嵌入失真和漏洞,以隐写的是明显比传统的量化索引调制(QIM)基于隐藏。不过,我是不太可靠的攻击,一台主机位错误导致多个解码错误隐藏位。在本文中,我们聘请了我-RA计划,我的藏身之具有强大的重复组合纠错累积(RA)的代码,来解决这个问题。本文的主要贡献是计算RA解码对数似然比,考虑到我的主机之间的系数和编码位多到一的映射。降低可探测性,我们隐藏在随机块,在最近提出的又一隐写计划(亚斯),由我-RA提出计划在
