What does setx -m do? Is it used in a command line to do something to an environmental variable?

setx -m OPENCV_DIR D:\OpenCV\Build\x86\vc10

I've tried several ways to reach http://opencv.willowgarage.com/wiki/InstallGuide over several days, but all came up with an "Try again.". Does anyone have the same problem?

I decided to take a look at NuGet. I betan as instructed with the Package Mgr Console. Apparently, I need to fire up VS C++ 2013 to reach it. followed the instructions down to The two drop-down lists set default values that let you omit parameters from the commands you enter in the window:

In the Package source list, select the default source (NuGet package feed) that you want your commands to use. Typically you will leave this as its default value of NuGet official package source. For more information about alternative feeds, see Hosting Your Own NuGet Feeds.
In the Default project list, select the default project that you want your commands to work with. .. I entered PM: Get-Package -ListAvailable and got a huge list. I'm stuck.

Oh, yes, I'm having lots of trouble figuring out how to configure 2.4.6!!! NuGet looks promising. I've made one change, an environmental variable, so I wonder if I need to return to its original value, or will Nuget figure it out? It is in the path variable. A system variable. path = .....%OPENCV_BUILD%\x64\VC10\bin. I think I added \x64\VC10\bin. I suspect opencv put in %OPENCV_BUILD%.

I'm using pre-built.

With a little research on Google, it appears cmake is a pretty heavy duty program. <http://www.cmake.org/cmake/help/cmake_tutorial.html> There's go to be another way to configure OpenCV.

As far as I know, I'm not using any cmake variables.

I don't use cmake.

I should have mentioned that I'm using pre-built, and 2.4.6. Do I need to go into command mode to somehow to find the actual value (path) of Open_DR. I have yet to come even close to getting a config started. I found in my path, ...\Tools\Binn\;%OPENCV_BUILD%\x64\VC10\bin. The install must have put it there.

A scalar is a number. A vector can be any tuple, (1,3),(4,8,20,6). ...

My question is in the Subject. cmake?

This is a fine description 2.4.7 installation and configuration. 19 min in length.

http://www.youtube.com/watch?v=POpMQPM9YlY!

It gave me a lot of tips that I could use for 2.4.6, which I'm still puzzled by. Where 2.4.6 and 2.4.7 part ways is the IDEs are dissimilar in dialogs and elsewhere. I can't match up matters that way. See the attached jpgs -- 2.4.7(1), 2.4.6(2) copies. Property Pages Not at all alike.

I'll take another shot at it.

Actually, the answer is yes. I noticed a set of approximately above and the one on the left of the paperclip allows it. I've often wondered about this for quite awhile, so maybe someone will profit by the post.

I've found a difference in 2.4.5 and 2.4.6 that has caused me to take pause. There's a problem in 2.4.6.

I installed 2.4.6 and have had lots of trouble installing and configuring it. It's was a lack of my understanding, newbie, on my part until I came across this, It's for 2.4.5,

http://opencv-srf.blogspot.com/2013/05/installing-configuring-opencv-with-vs.html?showComment=1393102435440#c6262055533993598838.

They key to getting anywhere seems to be setting up environmental variables in the "System-> Advanced System Setting" (Control Panel). Those and some in the configuration. After the install, There are two values to set: TEMP and path. The first involves inserting OPENCV_DIR to the value, and the second inserting OPENCV_DIR value. The second requires setting the sys architecture, x86 or x64. That plus the compiler type, ..., vc9, vc10, ... Pretty simple.

For the configuration, one needs to change The Additional Include Directories, and the Additional lib Directories. $(OPENCV_DIR)\include and $(OPENCV_DIR)\x86\vc11\lib. Getting there requires one to work through a New Project, Solution Directory, to two Property Changes dialogs. These last two get the include and lib values above.

Here's my problem. The last values cannot be placed into the directories. How do I find the place to insert them in 2.4.6?

I'm surprised that there isn't a document that describes all this. As it turns out there is. <http://opencv-srf.blogspot.com/2013/05/installing-configuring-opencv-with-vs.html> Well done.

I've installed OpenCV, but appears that one must do more. That is somehow provide paths to bins, libs, and who knows what else to be executable under VS c++ 2013? I'm pretty much clueless. Some considerations are: path = C:\Windows\system32;....C:\QTSystem;...\OPENVbin\blah; ..;%OPENCV_BUILD%\x64\VC10\bin, or OPENCV_BUILD = C:\Robert\opencv\246\build.

Somehow these samples don't seem right for providing a paths that I think I'm looking for, but maybe OPENCV_BUILD = C:\Robert\opencv\246\build;C:\opencv\build\bin ...?

Comments?

Thanks. Username click doesn't work for me. I get on the pulldown list, "Open Link in New Tab" at the top of a typical list. However, the 4957 link gives me a single window with my posts. That sure is an odd way to do it.

Subject is my question.

Where's the delete?

Yep, that's the question.

I'm using Windows 7. I thought I was looking for the path environmental variable, as in path = C:\Windows\system32;......;%OPENCV_BUILD%\x64\VC10\bin. or OPENCV_BUILD = C:\Robert\opencv\246\build. I got this notion from the "... Build Application ..." doc. Quoting the doc, "If you use the lib system you must set the path where the library files are and specify in which one of them to look." In the paragraph below this statement, I see "If you use the DLL system you must again specify all this, however now for a different reason" Presumably one needs a path to the DLLs. Apparently, I need something for debug or release--whatever that is!.

In OpenCV 2.4.6, how do I find the path where the library is?

How about the DLL path for the Linker?

So I need not worry about them if I don't use the Vs?

I was prowling around in my VS C++ 2013 install folder told, and found V9, V10, and V11 folders under a high level build folder. They, the Vs, contained bin, lib the staticlib. What are the three V folders for? Similarly why is mingw in another folder? That's a C++ compiler. A quick look with Google showed there may some agreement between MS and mingw.

I took a look at the bug wiki and don't see a way to put my question above reported.

In a previous post of mine, I was told that this doc link was needed to get started with a simple application. http://docs.opencv.org/trunk/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#windows-visual-studio-how-to

It describes two methods, local, and global. In the global section, it appears it is relevant to VS 2008 and VS 2010. My first question, since I use 2013, where can this material for it be found?

Personally, I'm baffled by what I see in this doc. It seems to apply to someone who is very familiar with the underlying material. I would appreciate it if the descriptions weren't so limited. For example, why local and global? What are they trying to describe? A good bit of this makes no sense to me. This may be worthy of a Bug Report per Help and Feedback in the last paragraph.

It seems to me there's a character limit here. I was stopped with repeatedl(y). Kind of a tiny window to work in.

Looking at the first link suggests that these steps are all I need for pre-built:

Installation by Using the Pre-built Libraries

1 Launch a web browser of choice and go to our page on Sourceforge.

2 Choose a build you want to use and download it.

3 Make sure you have admin rights. Unpack the self-extracting archive.

4 You can check the installation at the chosen path as you can see below.

5 To finalize the installation go to the Set the OpenCV enviroment variable and add it to the systems path section.

Seems pretty straightforward.

The second link is about building an application, and looks a bit daunting. It looks like it's a one-time set-up, I hope! In other words, it doesn't need any changes to Local the next time, but a different project can be used here repeatedl

Is it the case that when one installs OpenCV that it makes the lib files, the function bin files, and (possibly) the header files? dll files? I see them in the OpenCV folder that is created.

My stumbling block with getting an executable program seems to be the libraries. In particular, I do not see how one makes a library function reachable from the C++ source code. I see a bunch of lib functions in the installed folder. ...->OpenCV->build->x86->vc11->lib. lib contains 41 lib functions, so at least they are known. How do I make the connection with the source code?

If one responds to an old comment, it has almost zero chance of being seen by anyone else. In my case, I just did respond to an old comment, because it didn't answer the question posed. Who's going to react to the post that far back?

I don't see how the lower link above provides insight to building libraries via the tutorials. All the tutorials do is show an example program. The word library is not mentioned.

I'm interested in a list of the contents of the library, Say Newton method, matrix inversion, interpolation, histograms, ... Well, I just did a little Googling, and four a 400+ page pdf by Intel that has descriptions, but no code. Here's a program <http://docs.opencv.org/trunk/doc/tutorials/introduction/display_image/display_image.html#explanation> I found a library download source at <http://sourceforge.net/projects/opencvlibrary/>, but have no idea whether it's worth opening. To be continued.

That's the question in Subject, but moreover does someone have a simple program that uses the library?

Somehow the last paragraph got bungled. Here's what it should be. It may have not provided end-of-lines because I used a couple of words in bold.

Tutorial to build a program Loose video milestones until imaging program is entered as text and compiled. He is assuming that one has made a Project before. If not, it's an interesting to see how it's done.

I seem to have a fair amount of trouble finding some simple way to install OpenCV. One such way is http://docs.opencv.org/doc/tutorials/introduction/windows_install/windows_install.html, but to me it doesn't fit the bill. BTW, I'd rather not build my libraries.

However, I found a video on YouTube that does fit the bill. http://www.youtube.com/watch?v=cgo0UitHfp8. It has two parts. 1. Install OpenCV, and 2. constructing a sample project. It takes the viewer through the process step by step. To illustrate as best I can in text, here's what I make of it. Consider the material as a guide to watching the video The video is built by Kyle Hounslow.

===========

First get the exe version of OpenCV you want. The exe file unzips the contents. Extract the material to some location on your machine. Maybe the desk top.

Control Panel->System (Left side) Advanced

In the upper panel of the Environmental Variables, enter: Variable Name: OPENCV_BUILD Variable Value: C:\opencv248\build

In the lower panel, enter: Edit->Path: \:bin;%OPENCV_BUILD%\x86\VC10\bin (Might need to use other than x86.)

RESTART COMPUTER!

I have a couple of old b/w photos. What methods are available to remove scratches?
