1)  detection of R wave
R波捡测
2)  R-wave detection
R波检测
1.
In this paper,an R-wave detection method using wavelet transform(WT)is presented in line with the principle of discrete wavelet transform(DWT) and multi-resolution technique(MRT).
该算法主要是在离散小波变换和多分辨率分析原理的基础上,利用db1小波特有的时频域特性,运用M a llat快速算法对心电信号进行了3层小波分解,分别在2、3层小波分解的高频系数中选择一定的阈值作为R波的判定条件,实现R波检测。
2.
This is a creative method besides its simplicity and high speed,the accuracy of R-wave detection was also improved by time-domain correction.
本文描述了一套基于小波理论进行心电信号处理的方案及其实现,即根据小波变换分解后,各个尺度上信号的特征采取相应的措施进行滤波或者R波检测。
3.
A combining algorithm of the Marr wavelets transform with nonlinear energy operator applying to R-wave detection of ECG signal is presented in this paper.
将Marr小波变换和非线性能量算子相结合实现了心电信号的R波检测,心电信号的Marr小波分解信号很好地抑制了各种噪声干扰,结合非线性能量算子运算可突出了QRS波的特征点,使得阈值检测便于实施,利用修正策略提高了R波检测率,经MIT/BIH标准心律失常数据库验证,R波的检测率可达到99。
3)  R wave detection
R波检测
1.
Research on new simple fast realtime R wave detection algorithm;
简单快速实时R波检测算法的研究
4)  wave detector
捡波器
5)  paper disease pick up measure
纸病捡测
1.
According to the hierarchical method of the paper quality, a kind of paper disease pick up measure system was designed, which based on picture pattern-recognition.
根据纸张质量分级方法,设计了一种基于图形模式识别的纸张纸病捡测系统。
6)  Ultrasonic leak detect
超声波捡漏
补充资料:捡挍
【捡挍】
 (术语)又作检校。谓于事点捡典挍而监查之也。四分律所谓:“应寻究修多罗毗尼,捡挍法律。”百一羯磨所谓:“言共印持者,如捡挍营作之苾刍,创起基石,将欲兴功,告共住诸苾刍曰:诸具寿,仁应共知,于此处当为僧伽作净厨。”是也。
