FindContour is used in ColorBlobDetector.cs at Line 91 I guess, The result is printed to the Log in ColorBlobDetecionActivity.cs  at Line 165. It is always zero. So i think, it has something to do with the FindContour funtion. I do not have any exceptions with that. Can you replicate this result?"},"comment":{"url":"https://api.github.com/repos/TrekDev/Xamarin.Android.OpenCV/issues/comments/206366190","html_url":"https://github.com/TrekDev/Xamarin.Android.OpenCV/issues/1#issuecomment-206366190","issue_url":"https://api.github.com/repos/TrekDev/Xamarin.Android.OpenCV/issues/1","id":206366190,"user":{"login":"TrekDev","id":7805013,"avatar_url":"https://avatars.githubusercontent.com/u/7805013?v=3","gravatar_id":"","url":"https://api.github.com/users/TrekDev","html_url":"https://github.com/TrekDev","followers_url":"https://api.github.com/users/TrekDev/followers","following_url":"https://api.github.com/users/TrekDev/following{/other_user}","gists_url":"https://api.github.com/users/TrekDev/gists{/gist_id}","starred_url":"https://api.github.com/users/TrekDev/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/TrekDev/subscriptions","organizations_url":"https://api.github.com/users/TrekDev/orgs","repos_url":"https://api.github.com/users/TrekDev/repos","events_url":"https://api.github.com/users/TrekDev/events{/privacy}","received_events_url":"https://api.github.com/users/TrekDev/received_events","type":"User","site_admin":false},"created_at":"2016-04-06T13:17:26Z","updated_at":"2016-04-06T13:17:26Z","body":"Hi CeadeS, I think I'm having the same problem. I may have mistranslated it from the SDK demo provided with the OpenCV SDK. I can't investigate it now as I don't have access to a machine with Xamarin on it today. You can [download the original SDK demo in Java here](https://sourceforge.net/projects/opencvlibrary/files/opencv-android/3.1.0/OpenCV-3.1.0-android-sdk.zip/download) and see where I may have gone wrong.\r\n\r\nIf I haven't translated it wrong it may be a problem with the bindings. If you find anything in the logs that may suggest where it is going wrong please post it back here. I'll have a look myself when I have the chance."}}
