针对GM(1,1)模型应用的局限性,根据实际应用的需要,利用灰色建模思想构建了含时间幂次项的灰色GM(1,1,t~α)模型,对该模型的建模过程、参数估计、时间响应式进行了研究,并讨论了α几种特殊取值下的该模型的性质、适用范围、时间响应式,并利用GM(1,1,t~2)对某沿海高速的软土地基沉降进行了拟合与预测,获得了较高的拟合与预测精度,通过实际应用检验了所构建的模型的有效性.

提出一种基于随机蕨丛的双层视频分割算法,实现对单目视频的自动分割.算法在对视频运动特征进行聚类的基础上,构造视频运动特征字典,通过随机蕨丛对运动特征进行建模.在此基础上利用条件随机场约束视频颜色、运动特征以及邻域关系,通过graph-cut算法求解出全局最优的分割结果.在实验中采用多种环境的视频数据对本文算法的有效性进行测试,并与其他分割算法的结果进行比较.
