【框架介绍】
OpenVINO(Open Visual Inference & Neural Network Optimization)是一个由Intel推出的,针对计算机视觉和机器学习任务的开源工具套件。通过优化神经网络,加速深度学习推理,OpenVINO可以帮助开发者更高效地在Intel硬件上部署机器学习应用。
OpenVINO的.NET版本是其与.NET生态系统的结合,提供了C#语言的API接口,让.NET开发者能更容易地集成和使用OpenVINO的功能。.NET开发者可以快速将OpenVINO的优化和加速能力集成到他们的应用中,提高图像和视频处理的速度。
使用OpenVINO.NET,开发者可以:
总的来说,OpenVINO.NET为.NET开发者提供了一个强大的工具,帮助他们快速构建高性能的机器学习和计算机视觉应用。通过优化神经网络和加速推理,OpenVINO.NET有助于推动AI技术在各种行业中的应用和发展。
