摘要 本文通过对人类视觉系统HVS(Human Visual System)的特点的分析,针对一般计算可感知噪声阈值矩阵方法均在频域进行且相对比较复杂的缺点,提出了一种类可感知噪声阈值矩阵,它可在空域直接计算。实验表明该方法简单、直观且具有较好的应用效果。 This paper presented a new perceptible noise threshold matrix algorithm that directly computed in spatial domain by analyzing the character of HVS (Human Visual System) and the deficiency of common percep- tible noise threshold matrix algorithm which usually be computed in frequency domain. Tests show that this al- gorithm is simple and effective.
