基于YOLOv8深度学习的高密度人脸智能检测与统计系统【python源码+Pyqt5界面+数据集+训练代码】深度学习实战、目标检测

背景及意义

高密度人脸智能检测与统计系统在当今越来越注重实时监测和数据分析的社会中扮演着关键角色。该系统能够快速有效地检测和统计出特定场景中的人脸数量，为人流管理、安全监控和资源配置提供了重要信息。本文基于YOLOv8深度学习框架，通过16102张人脸相关图片，训练了一个进行人脸目标检测的模型,可以对密集人群的人脸进行实时检测。并基于此模型开发了一款带UI界面的高密度人脸智能检测与统计系统，更便于进行功能的展示。该系统是基于python与PyQT5开发的，支持图片、视频以及摄像头进行目标检测，并保存检测结果。本文提供了完整的Python代码和使用教程，给感兴趣的小伙伴参考学习，完整的代码资源文件获取方式见文末。
