Then proposes a video image pre-processing method based on adaptive neighborhood statistics. The proposed pre-processing conquers the low efficiency of classical adaptive neighborhood filter and the sensitivity to threshold in other methods.

提出了一种基于自适应邻域统计的视频图像预处理算法，该算法解决了自适应邻域滤波中邻域构建的效率问题和传统预处理算法的门限敏感问题。

This method pre filters input data by the orthonormal basis functions in order to get some dynamic characteristics. Unfortunately, the gradient algorithm could not be directly used in parameter identification because the pre-filtered data do not have time shift characteristic anymore.

该方法通过正交基函数对输入数据进行滤波，使得滤波后的数据蕴涵着系统的部分动态特性，但也使滤波后的数据不再满足时移特性，因而无法直接使用梯度算法对模型参数进行辫识。

The importance of studying shrinking of polystyrene pattern for evaporative pattern casting is pointed out in this paper.After studying effects of technological factorsexpandable polystyrene(EPSbead diameter,pre-expansion time,age time of pre-expansion bead,molding steam pressure,storage time and temperature of pattern on shrinking of pattern,it is shown that the stress relaxation of pattern and the escape of pentane and water in pattern are main cause of pattern shrinking.

指出了对消失模铸造用聚苯乙烯模样收缩展开研究的必要性，研究了可发性聚苯乙烯珠粒粒径、预发泡时间、预发泡珠粒熟化时间、成形蒸汽压力及模样的放置时间、贮存温度对模样收缩的影响，认为模样中发泡剂和水分的挥发以及应力的释放是引起模样收缩的主要原因，最后提出了在实际生产中为减少模样收缩应采取的措施。
