Hi i use DEV C++ compiler in windows xp sp2 and recently i downloaded the IPP libraries. I installed successfully , i set up the compiler directories from option menu to IPP directories but when i try to compile an ITT program i get linker error for the ITT functions. Is there a solution? ...
Hello, I am working for a project at school regarding face recognition, based on a technique described by Viola and Jones 2001/2004. I've read that the OpenCV has an implementation of this algorithm, and it works very good. I was wondering if you have any advices regarding what techniques (pre-processing) to apply to the images befor...
I need to install OpenCV on Win32. I do not have it installed currently. I downloaded OpenCV-2.0.0a-win32.exe and ran it. What the heck do I do now? There are no .lib's and whatnot. I found some instructions for building the release using cmake at http://opencv.willowgarage.com/wiki/InstallGuide . I downloaded the latest and greates...
Hello, I am using OpenCV 1 to do some image processing, and am confused about the cvSetErrMode function (which is part of CxCore). OpenCV has three error modes. Leaf: The program is terminated after the error handler is called. Parent: The program is not terminated, but the error handler is called. Silent: Similar to Parent mode...
I am using opencv 1.0.0 and gtk2.0. I want to grab images continuously from a video stream. So far I have successfully been able to grab still image. This is non standard IP camera not VGA/USB /V4L one so need to know explicit method to refresh or update images continuously for video streaming! GtkWidget *image; ... ... IplImage* ba...
I have a camera that will be stationary, pointed at an indoors area. People will walk past the camera, within about 5 meters of it. Using OpenCV, I want to detect individuals walking past - my ideal return is an array of detected individuals, with bounding rectangles. I've looked at several of the built-in samples: None of the Python ...
I cannot get the example Python programs to run. When executing the Python command "from opencv import cv" I get the message "ImportError: No module named _cv". There is a stale _cv.pyd in the site-packages directory, but no _cv.py anywhere. See step 5 below. MS Windows XP, VC++ 2008, Python 2.6, OpenCV 2.0 Here's what I have done. ...

I want to use OpenCV's image processing functions, but not the OpenCV GUI. I'm using OpenCV 2.0. I will use either Qt4 or WxWidgets for GUI functions. I compile with VC++ 2008 Express (VC++ 9.0). I guess it breaks down to two or three questions: Is it necessary to do something to disable OpenCV's higui so it does not interfere with...
Hi Everyone, I installed opencv2.0 and I am using MSV c++ 2008 v9. I tested some code online that return the inverted version of a singel static image, but I would like to see the FaceDetect code working as well. I tried following the instructions in the wiki but I get a memory alocation error coming from a file I am not supposed to edi...
I am working in image processing in C++ using OpenCV. I've a problem that requires cubic interpolation of a set of data. Are there any library files that I can use for this in OpenCV? ...
Hi Im on mac snow leopard and test these code on xcode3.2 of the Learning OpenCV everything works fine but the image doesnt appear and in the windows. I had try to understand searching for two days what does argv[1] means, but Im still no clear. Im a newbie en C++. I had the image in the same directory where the main.cpp is #include <Op...
Having successfully installed opencv 2.0 with python bindings I'm starting to run into trouble and before I go any further I wondered if I should change to another option. As ezod on this post says: "As a caveat, as of the 2.0 release, the new Python bindings are incomplete: many functions I would consider rather important missing. Mean...
Hi, Since I am very UNHAPPY with Visual Studio (It's just Junk!) I am trying to use QT creator, which seems to be the solution for my c++ projects to get easily run in my Mac also. But I am using OpenCV. So, How do I set libraries in QT? (include folder and maybe some libs) I am trying with this app: http://www.qt-apps.org/content/show...
I have a jpeg. Its color profile is sRGB, of course. I load it into "image" and call cvCvtColor(image, gray, CV_BGR2GRAY); to convert it to grayscale. When I step into that routine in the debugger, I find it multiplying pixels by these values: #define cscGr_32f 0.299f #define cscGg_32f 0.587f #define cscGb_32f 0.114f Waaaai...

I am assuming that using the OpenCV code here: http://github.com/billmccord/OpenCV-Android#readme is the best way to use OpenCV on Android, with the NDK. I am still stuck as to how i get from the C definitions of functions to the ones i declare in OpenCV.java in my Android project (example: cvFindContours( void* img, CvMemStorage...
below is a very simple code segment, but I am not able to understand why it is cribbing, can you please tell me what the error means: CvSize iSize; iSize= cvGetSize(I1); CvLineIterator *iter ; CvPoint p1,p2; long *arrH = new long[iSize.height + 1]; long *arrV = new long [iSize.width + 1]; for( int i=0; i<=iSize.height;i++) { ...
I have a problem with my program written in Visual C++ using OpenCV: i have to capture frames from webcam and find all the various rectangle (it doesn't matter the color). I try to modify the samples in c, squares.c, but it doesn't work as well, because the program wait any key (different from 'q') to continue. This is the code. Someon...
What is the best way (in c/c++) to rotate an IplImage by 90 degrees? I would assume that there must be something better than transforming it using a matrix, but I can't seem to find anything other than that in the API and online. ...
