| 9. | According to minimum mean absolute difference criteria ( mad ) , our paper uses three - step search algorithm to get the block vectors in two sequential images . main direction of object motion could be obtained by classifying and the average vector on main direction is the vector of whole object . this thesis starts with an introduction of the motion analysis 根据最小平均绝对差值( mad )准则,利用三步搜索算法,计算出相邻两帧视频图象中各子块的运动矢量,该算法通过对运动矢量场中的运动矢量进行统计、分类,找到物体运动的主要方向,而主运动方向上的平均运动矢量就是物体运动的整体矢量。 |
| 10. | A modified genetic algorithm ( mga ) framework was developed and applied to the flowshop sequencing problems with objective of minimizing mean total flowtime . to improve the general genetic algorithm routine , two operations were introduced into the framework . firstly , the worst points were filtered off in each generation and replaced with the best individuals found in previous generations ; secondly , the most promising individual was selectively cultivating if a certain number of recent generations have not been improved yet . under conditions of flowshop machine , the initial population generation and crossover function can also be improved when the mga framework is implemented . computational experiments with random samples show that the mga is superior to general genetic algorithm in performance and comparable to special - purpose heuristic algorithms . the mga framework can also be easily extended to other optimizations even though it will be implemented differently in detail 提出了一个改进遗传算法的结构,并且应用于带有目标是最小平均总流程时间的流水调度排序中.为了改进一般遗传算法的程序,两个新的操作被引进到这个操作中.这两个操作为: 1 )过滤操作:过滤掉在每一代中的最坏的个体,用前一代中的最好的个体替代它; 2 )培育操作:当在一定代数内算法不改进时,选择一个培育操作用于培育最有希望的个体.通过大量的随机产生的问题的例子的计算机实验显示出,提出的算法的性能明显好于一般遗传算法,并且和此问题的最好的专门意义的启发式算法相匹配.新的mga框架很容易扩展到其它最优化当中,只是实施的详细的步骤有所不同 |
