| 9. | For the third type , the blood ' s speed is very fast in a frame and maybe very slow in the next frame . it is difficult to measure the velocity using a standard video system but can be measured with high - speed video camera system [ 17 , 42 , 43 ]
第三类微血管内血液流动特性是时快时慢，很难在标准视频设备下测量出来，但如果在高速采集卡下的视频图象和第一类一样时，可以用第一类相同的方法测量出来。 |
| 10. | 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。 |
