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

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。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是从PhysioNet数据库中查看波形数据的主要工具。WAVE的功能包括：(1)在各种校准尺度下快速显示波形和注释；(2)快速访问记录的任何部分，使用缓存和“预读”启发式来提高效率并减少网络流量；(3)向前和向后搜索注释模式；（四）使用标准标注或者自定义标注进行图形化标注编辑；(5)变速叠加显示；(6)用户选择信号段的高分辨率打印；(7)对外部信号处理和分析的极为灵活的控制；(8)“远程”模式，允许网络浏览器等外部程序控制WAVE的显示；(9)多个WAVE过程（在同一或不同计算机上）的同步，以提供不同规模的数据的多个视图，并用于远程医疗应用和协作，广泛分布的可视化数据分析；（10）所有控件的在线“现场”帮助，以及额外的面向主题的在线帮助。最初的Unix WAVE实现是使用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.
