Car detection in Opencv LBP cascade to download

LBP cascade for Car detection in Opencv

LBP ( included to download) and Haar features in opencv detectMultiscale are one of the most simple and also powerfull (Old sure) to detect something. In this article is pre trained LBP cascade for car detection. Code and basic info. Results are not that bad. Check the video and enjoy pretrained cascade.

Opencv cascade for car detection conditions of use

Also, Do not worry about the condition of use. Use only on your own risk. That's it. The dataset to train this cascade is only mine. I also colect positive and negative data. I just want to say, that there is also no conditions based on the datasets. There is no others conditions of use. Maybe check the Opencv traincascade utility. Thanks. Yes share and cite. Just small minimal condition.

Opencv video results

Set Opencv Project in VS2015

You can simple prepare the project inside the Visual Studio 2015 by Nuget Packages. This approach is easy for beginers and better than standard installation with all the environmental variables problems. Just follow the installation steps inside here

How to use LBP cascade in OPENCV

Just Copy downloaded cascade inside the VS 2015 project dir.

    }
   }

   imshow("det", original);
   int key6 = waitKey(40);

   resize(original, original, Size(640, 480));
   outputVideo << original;

  
  }

 }
