We propose a project in collaboration with ViVitro Labs Inc., a Canadian company that offers industry-leading cardiovascular test equipment and related laboratory testing and consulting services. Through their cardiovascular testing and consulting services, ViVitro Labs Inc. helps to improve products meet regulatory requirements for independent third-party testing for FDA audit compliance and other regulatory submissions. We aim to address the issue of automating the analysis of video footage acquired during valve testing. Our investigations will focus on researching computer vision methods that can be used by the company for the automatic quantitative analysis of pulsatile and durability testing videos. The general idea is to develop quantitative evaluation metrics and apply them the testing videos; these metrics would complement current measurement techniques on pressure and flow data and replace the current qualitative, operator-based analysis of video footage. The development of a framework for the automatic quantitative analysis of pulsatile and durability testing videos would lay the ground work toward an automated production line tester that would effectively and reliably make a pass/fail assessment of the device performance when compared to a baseline.

我们提出了一个与ViVitro Labs Inc.合作的项目，ViVitro Labs Inc.是一家加拿大公司，提供行业领先的 心血管检测设备及相关实验室检测和咨询服务。通过他们的 心血管测试和咨询服务，ViVitro Labs Inc.帮助改进产品满足监管要求 对FDA审计合规性和其他监管提交的独立第三方测试的要求。 我们的目标是解决自动分析阀门测试过程中采集的视频片段的问题。我们的 调查将集中于研究计算机视觉方法，这些方法可供该公司用于 脉动和耐久性测试视频的自动定量分析。总体思路是发展 量化评估指标并将其应用于测试视频；这些指标将补充当前 基于压力和流量数据的测量技术，取代当前基于操作员的定性分析 一段视频片段。 脉动和耐久试验自动定量分析框架的研制 视频将为自动化生产线测试仪奠定基础，它将有效和 在与基准进行比较时，可靠地对设备性能进行通过/失败评估。
