做了一个工具箱，发表文章讲讲这个工具箱大概是怎么做的。

Abstract与Introduction
| 一些常用缩写 | 资源链接/备注 |
| FECGSYN toolbox | |
| NI-FECG | noninvasive fetal ECG |
| SQIs | signal quality indices |
| FHR | fetal heart rate |
| Krippendorff's alpha | 一致度检验 |
| FQRS | fetal QRS |
| MECG | maternal ECG |
| MQRS | maternal QRS |
| chest-lead | 头胸导联 |
| MHR | maternal HR |
| HDR | heartbeat detection rate |
| KF | Kalman Filter |
1) how can the quality of NI-FECG be quantified in scenarios of low/varying SNR?
怎么评价信号质量?
2) how can one fuse the information of multiple NI-FECG channels when segments/channels containing erroneous detec-
tions are present?
如果出现错误的检测,如何融合多通道的NI-FECG信息?
These SQI metrics are thoroughly evaluated concerning their ability to mirror the overall quality of NI-FECG signals by using a Naive Bayes classifier.The resulting quality estimates are evaluated using manually annotated clinical data and are further incorporated into a multichannel KF framework for improving fetal heart rate (FHR) estimates.
The developed SQI algorithms as well as resulting classifier were made available under a GNU GPL open-source license and contributed to the FECGSYN toolbox [12], [13] (available at www.fecgsyn.com).
这篇文章的工作就是制作了FECGSYN这个工具箱，
