Basic function to locate and measure the positive peaks in a noisy
data sets. Detects peaks by looking for downward zero-crossings
in the smoothed third derivative that exceed SlopeThreshold
and peak amplitudes that exceed AmpThreshold. Determines,

技术资料 改进的基于小波域隐Markov树模型的图像复原
·摘 要:针对传统的基于小波域隐Markov树模型的图像复原算法运算时间长以及对噪声敏感的问题，提出了一种快速并且鲁棒的复原算法。首先使用改进的ForwaRD算法，由混合线性时不变Wiener反卷积和平稳小波阈值收缩算法对退化图像进行预处理，将其结果作为模型参数训练和隐藏状态概率求取的样本。然后分别通过EM算法和Upward— ...
