I'm trying to track the movement of eyes using opencv for a windows store app i'm making in c#.

i have the live feed from the camera using MediaCapture.

i've been looking this up online for so long and i see people referring to MSOpenTech/opencv here but i can't follow the instructions because the readme file is outdated.

i also cloned the repository to try and run the sample code and when I run the winrt_universal phoneTutorial I keep getting the erorr :

The build tools for v120_wp81 (Platform Toolset = 'v120_wp81') cannot be found. To build using the v120_wp81 build tools, please install v120_wp81 build tools. Alternatively, you may upgrade to the current Visual Studio tools by selecting the Project menu or right-click the solution, and then selecting "Upgrade Solution..."

i don't know what i'm doing wrong with the sample and i'm not sure how to go about following the instructions for the opencv.

thank you!

The sample project targets Windows Phone 8.1.

To compile and run it, you need to install Visual Studio 2013 (you can get Community Edition from here: http://go.microsoft.com/?linkid=9863608)

  • If you are using Visual Studio 2013 and still getting error then according to http://stackoverflow.com/questions/19801072/the-builds-tools-for-v120-platform-toolset-v120-cannot-be-found maybe the wrong MSBuild is used. – Damir Tesanovic Mar 25 '15 at 22:01
