使用计算机视觉的交通信号违章检测系统 介绍 这是一种用于从头开始开发系统的软件。 理解这一点将有助于系统开发和系统的基本结构,以及计算机视觉,带有python库Tkinter的GUI和基本的opencv。 如果没有时间,请去。 表中的内容 动机 该项目是为第三学期第二学期系统开发(CSE-3200)课程而设计的。 介绍 城市中越来越多的汽车会导致大量的交通,这意味着在孟加拉国乃至世界范围内,如今违反交通法规的行为变得越来越严重。 这造成财产的严重破坏和更多的事故,可能危及人民的生命。 为了解决警报问题并防止此类不可思议的后果,需要使用交通违规检测系统。 系统会始终为此执行适当的交通法规,并逮捕不遵守法规的人员。 由于当局一直在跟踪道路,因此必须实时实现交通违章检测系统。 因此,交通执法人员不仅可以轻松准确地实施安全道路,而且还可以有效地进行道路建设。 交通检测系统能够比人类更快地检测到违

欢迎想入门CNN和深度学习的朋友们阅读论文。 GoogleNet始于LeNet-5,一个有着标准的堆叠式卷积层冰带有一个或多个全连接层的结构的卷积神经网络。通常使用dropout来针对过拟合问题。  为了提出一个更深的网络,GoogLeNet做到了22层,利用inception结构,这个结构很好地利用了网络中的计算资源,并且在不增加计算负载的情况下,增加网络的宽度和深度。同时,为了优化网络质量,采用了Hebbian原理和多尺度处理。GoogLeNet在分类和检测上都取得了不错的效果。  最近深度学习的发展,大多来源于新的想法,算法以及网络结构的改善,而不是依赖于硬件,新的数据集,更深的网络,并且深度学习的研究不应该完全专注于精确度的问题上,而更应该关注与网络结构的改善方面的工作。
