  Install (A short checklist for installing OpenCVDotNet) Wiki page commented on by aghoshbabu007   -   Dear david.pocivalnik, The error you getting is because you are trying to install the latest version of the openCV where as openCVdotNet currently supports OpenCV 1.0 only, the OpenCV 2.0 file naming conventions are different, so the openCVDotNet us unable to find the re-named file binaries in openCV 2.0....hope this helps somebody..!

  issue 23 (Installer fails to find OpenCV on 64-bit Windows) reported by JohannesH1980   -   Repro steps: 1. Install OpenCV in default folder(#1) in 64-bit Windows (Vista or 7) 2. Install OpenCVDotNet 3. Celebrate The expected result of these steps is that OpenCVDotNet installs successfully if I've already installed OpenCV, which I have, after which I celebrate and make some beautiful code. Unfortunately I never get past step 2. I suggest that if OpenCVDotNet can't automatically find the OpenCV binaries it should ask the user to provide a path through a folder chooser dialog box or similar UI. ---------- OpenCVDotNet version: 0.7 OS: Windows 7, 64-bit, english ---------- #1: The default folder is "%programfiles(x86)%\opencv\" in my current OS. Which translates to the path "c:\program files (x86)\opencv\". In a non- english OS the actual folder might also be different no matter if it's an x86 or x64 OS. In a danish x86 Windows XP, OpenCV would be installed in the path "%programfiles%\opencv\" which points to "c:\programmer\opencv\".

  issue 7 (program not starting: 0x800736B1) commented on by nicolas.teixeira   -   Thanks a lot 84yelo3!!! That .dll worked for me. I'm using: Microsoft Visual Studio 2008 Version 9.0.21022.8 RTM Microsoft .NET Framework Version 3.5 SP1 Installed Edition: C# Express @WinXP SP3 It's strange because this error is due the lack of the VC++ 2005 SP1 Redistributable Package (vcredist_x86.exe) and my system has the VC++ 2008 Redistributable... Theoretically, it should work fine...

  issue 18 (Human being tracking) reported by anguoyang   -   I am not experienced in OpenCV and related algorithms, so maybe my question is not so technical: I want to develop a demo program which could determine if there is person or not(that means, it could tell me if there is a human being or not in the current frame/picture, the existence of a human being in a picture), but when I try the sample program in mean-shift mode, the rectangle could track the human being precisely, and I don't know if it could determine "human being" from a single picture/frame or not, I am not familiar with mean-shift algorithm, so, could you please give me some advices? Another requirement for this demo is to determine the existence of balustrade --- a long rod in the picture,could you also give some advices for me? thanks in advance.

  What steps will reproduce the problem? 1. Download and install openCV for WinXP (OpenCV_1.1pre1a.exe with dll named *110.dll instead of *100.dll) 2. Try to install last release of OpenCVDotNet 3. Fail to install due to bad openCV's dll names. What is the expected output? - A Complete installation What do you see instead? - Failing to install What version of the product are you using? - opencvdotnet-0.7-setup.exe On what operating system? - Windows XP

  issue 10 (Cannot install when operating system is installed on a drive...) commented on by florinracila   -   I have the same error with "opencvdotnet-0.7-setup.exe". I have 2 Windows OS on my system and the one I'm working on is on D. OpenCV folder is D:\Program Files\OpenCV\. It would be usefull to ask me in a previuos window wich is my OpenCV folder...right?

  issue 1 (File Not Found Exception : Exception from HRESULT: 0x8007007...) commented on by tim.stclair   -   This worked for me: (I have VS2008) ----------------------------------- I installed OpenCV first, then installed the OpenCVDotNet second. I then opened the Examples.csproj in VS2008 and converted it. I then removed all the references to OpenCVDotNet, OpenCVDotNet.Algorithms and OpenCVDotNet.UI I then added these projects from the OpenCVDotNet\src folder and fixed up the references to be project references rather than the DLL's (converting the projects to 2008 as I went). I've found that this is usually the best thing for a number of projects I work with where I get the FileNotFound exception. I checked the library paths in c++ and it had found the C:\Program Files\OpenCV\lib folder happily. I pressed "Run" and off it went. I've attached my VS2008 solution file and the other bits and bobs that it created.

  issue 15 (Enable to get frame from 2 cam) reported by marco.garnier   -   What steps will reproduce the problem? 1. create 2 CVCapture object : cap1 = new CVCapture(0); and cap2 = new CVCapture(1) 2. try to get frame from the cam every seconds : using (CVImage nextFrame = cap1.QueryFrame()) { pictureBox1.Image = nextFrame.ToBitmap(); } using (CVImage nextFrame = cap2.QueryFrame()) { pictureBox2.Image = nextFrame.ToBitmap(); } What is the expected output? What do you see instead? Sometime pictureBox2 stay black, sometime i have a NullPointer Exception when try to execute nextFrame.ToBitmap() What version of the product are you using? On what operating system? OpenCVDotNet 0.7, WinXP SP2 Please provide any additional information below.
