这是盲图像质量因子(BIQI)的MATLAB源代码. 该算法由A. K. Moorthy 、A. C. Bovik等人在 A Modular Framework for Constructing Blind Universal Quality Indices 中提出，发表在IEEE Signal Processing Letters (2009). (This is blind image quality factor (BIQI) MATLAB source code for this algorithm in " A Modular Framework for Constructing Blind Universal Quality Indices" proposed by the AK Moorthy, AC Bovik et al., Published in the IEEE Signal Processing Letters (2009).)

说明：  两种不同的假设： H1 ： 0 xn A fn wn ( ) cos(2 ) ( ) = ++ π θ n=1,2,…,N，f0 为规一化频率 H0 ： xn wn () () = n=1,2,…,N 其中 w[n]是均值为 0，方差为 2 σ n 的高斯白噪声，A 已知，样本间相互 独立，信号与噪声相互独立; 相位θ 是随机变量，它服从均匀分布 1 0 2 ( ) 20 p θ π θ π ?? ≤ ≤ = ??? 其它 1）改变输入信噪比（改变 A 或噪声方差均可），给定虚警概率，画出 输入信噪比与检测概率之间的理论曲线。(注意：理论检测曲线与样本 数有关) 2）改变样本数，用 Monte-Carlo 实验方法得出 PF＝0.001 时输入信噪比 与检测概率之间关系曲线（至少三条），并得出结论。 3）改变 M-C 实验次数，样本数不变，用 Monte-Carlo 实验方法得出 PF ＝0.001 时输入信噪比与检测概率之间关系曲线（至少三条），并得出 结论。(Draw the theoretical curve between input SNR and detection probability)

说明：  RS码(Reed—Solomon码)是多进制BCH码，也是目前最有效、应用最广泛的差错控制编码。它具有很强的纠错能力，随机错误、突发错误都能纠正，特别是在短的和中等码长其性能接近于理论值。再加上构造方便，编码简单，设备不复杂，因此在实时性要求较高的数字通信及深空通信方面有广泛应用(RS code ( Reed- Solomon code ) is a multiple of BCH code, is currently the most effective, the most widely used error control coding. It has a strong error correction ability, random error, burst error can be corrected, especially on short and medium length code performance close to the theoretical value. Plus convenient construction, simple coding, equipment is not complex, so the real-time digital communication and deep space communication is widely used )
