It can be used in real time situation . for the second type , the blood flow ' s speed is very high ( fig . 3 . 5 ) . average speed of a frame can be measured using fft 第二类血管内的血液流速很高(见图3 . 5 ) ,看不清细胞,本文用傅立叶变换,可以求出每帧血液的流速。
Traffic flux and average speed detection are realized based on visual c + + , in addition , the idea is brought forward that to recognize vehicles by its aspect ratio 同时,以visualc + + 6 . 0为平台,实现了车流量和平均车速的检测,并提出了以车辆长宽比为依据的车型识别思想。
4 . a formula for calculating receiving buffer length was proposed , based on the analysis and research on network parameters , such as jitter , average speed and packet loss fraction 4 .在分析研究延时抖动、平均速率和丢包率等网络参数的基础上,给出客户端接收缓冲区长度估算公式。
Average speed calculation vecon - speed vecon - speed is an efficient and accurate system that calculates the average speed of a vehicle between two pre - determined fixed points 平均速度统计慧光道路车速监察系统vecon speed是一个高效高精确度的用于测量某一固定路段车辆通行平均速度的系统。
In the third part , we analyzed the relations not only between space average speed v and amplitude - weighted average speed v , but also between space speed variance x and frequency speed variance f )和空间域平均速度( ? )之间、频率域速度标准差_ f和空间域速度标准差_ x之间的关系,揭示(
