无所遁形——快把你的口罩戴上(口罩识别)

        人脸识别,是基于人的脸部特征信息进行身份识别的一种生物识别技术。用摄像机或摄像头采集含有人脸的图像或视频流,并自动在图像中检测和跟踪人脸,进而对检测到的人脸进行脸部识别的一系列相关技术,通常也叫做人像识别、面部识别。

疫情当下,学校封校,教室上网课,食堂就餐等等环境,口罩佩戴依旧十分有意义,单靠人员监测效率太过低下,笔者就在考虑能否让计算机完成相关工作,就查阅了相关资料,在开源训练集的基础上,设计了本款口罩识别。

插播一句,深度学习的项目目前完全开源,大家可以先体验体验:

https://demo.aizoo.com/face-mask-detection.html

        深度学习(DL, Deep Learning)是机器学习(ML, Machine Learning)领域中一个新的研究方向,它被引入机器学习使其更接近于最初的目标——人工智能(AI, Artificial Intelligence)。 
        深度学习是学习样本数据的内在规律和表示层次,这些学习过程中获得的信息对诸如文字,图像和声音等数据的解释有很大的帮助。它的最终目标是让机器能够像人一样具有分析学习能力,能够识别文字、图像和声音等数据。 深度学习是一个复杂的机器学习算法,在语音和图像识别方面取得的效果,远远超过先前相关技术。
        深度学习在搜索技术,数据挖掘,机器学习,机器翻译,自然语言处理,多媒体学习,语音,推荐和个性化技术,以及其他相关领域都取得了很多成果。深度学习使机器模仿视听和思考等人类的活动,解决了很多复杂的模式识别难题,使得人工智能相关技术取得了很大进步。
