WAVE SOFTWARE FOR VIEWING, EDITING, & ANALYSIS OF PHYSIOLOGIC SIGNALS

该子项目是利用NIH/NCRR资助的中心赠款提供的资源的许多研究子项目之一。子项目和研究者（PI）可能从另一个NIH来源获得主要资金，因此可以在其他CRISP条目中表示。所列机构为中心机构，不一定为研究者机构。WAVE是一个可扩展的交互式图形环境，用于操作带有可选注释的数字化信号集。WAVE是查看PhysioNet数据库中波形数据的主要工具。WAVE的功能包括：（1）以各种校准比例快速显示波形和注释;（2）快速访问记录的任何部分，具有高速缓存和“预读”算法以提高效率并减少网络流量;（3）向前和向后搜索注释模式;（4）使用标准或用户定义的注释进行图形注释编辑;（5）可变速度叠加显示;（6）用户选择的信号段的高分辨率打印;（7）外部信号处理和分析的极其灵活的控制;（8）“远程”模式，允许外部程序如Web浏览器控制WAVE的显示;（9）多个WAVE进程的同步（在同一台或不同的计算机上）提供不同规模的数据的多种视图，并用于远程医疗应用和协作、广泛分布的可视数据分析;以及（10）所有控件的在线“spot”帮助，以及附加的面向主题的在线帮助。WAVE for Unix的最初实现，使用XView GUI工具包，于1990年首次发布;该版本仍在持续开发和使用中。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. WAVE is an extensible interactive graphical environment for manipulating sets of digitized signals with optional annotations. WAVE is the primary tool for viewing waveform data from PhysioNet databases. WAVE's capabilities include: (1) fast display of waveforms and annotations at various calibrated scales; (2) fast access to any portion of a recording, with caching and `read-ahead' heuristics to improve efficiency and reduce network traffic; (3) forward and backward searches for annotation patterns; (4) graphical annotation editing using standard or user-defined annotations; (5) variable-speed superimposition display; (6) high-resolution printing of user-selected signal segments; (7) extremely flexible control of external signal-processing and analysis; (8) 'remote' mode, allowing external programs such as Web browsers to control WAVE's display; (9) synchronization of multiple WAVE processes (on the same or different computers) to provide multiple views of data at varying scales and for telemedicine applications and collaborative, widely distributed visual data analysis; and (10) on-line `spot' help for all controls, with additional topic-oriented on-line help. The original implementation of WAVE for Unix, using the XView GUI toolkit, was first released in 1990; this version remains in continuous development and use.
