This is throwing about 20 errors. Including error C4430: missing type specifier - int assumed.

I'm really sorry about it.Since I felt I could get some kinda help here also, I'm asking in this forum. I will make sure not to overload with DLib questions.

It throws the same.

The following isn't related to OpenCV though, Now it's throwing while compiling D:\Ram\Projects\DLib19\dlib-19.0\examples\face_landmark_detection_exram.cpp(109): error C2872: 'rectangle' : ambiguous symbol [D:\Ram\Projects\DLib19\dlib-19.0\examples\build\face_landmark_detection_exram.vcxproj] could be 'rectangle' or 'd:\ram\software\dlib\dlib-19.0\dlib\geometry/rectangle.h(20) : dlib::rectangle' D:\Ram\Projects\DLib19\dlib-19.0\examples\face_landmark_detection_exram.cpp(109): error C2923: 'std::vector' : 'cv::rec tangle' is not a valid template type argument for parameter '_Ty' [D:\Ram\Projects\DLib19\dlib-19.0\examples\build\face _landmark_detection_exram.vcxproj]

This Mat is throwing intellisense error in visual studio. Which header should I include.

I have this code following the above,

CvPoint P1; P1.x = 200; P1.y = 417;

        cv::Mat image;
        image.at<cv::Vec3b>(P1.y, P1.x);

        image.at<cv::Vec3b>(P1.y, P1.x)[0] = 140;
        image.at<cv::Vec3b>(P1.y, P1.x)[1] = 160;
        image.at<cv::Vec3b>(P1.y, P1.x)[2] = 160;

CvPoint P1; P1.x = 200; P1.y = 417;

        cv::Mat image;
        image.at<cv::Vec3b>(P1.y, P1.x);

        image.at<cv::Vec3b>(P1.y, P1.x)[0] = 140;
        image.at<cv::Vec3b>(P1.y, P1.x)[1] = 160;
        image.at<cv::Vec3b>(P1.y, P1.x)[2] = 160;

I used OpenCV2.4.13 and I got OpenCV Error: Assertion failed (dims <= 2 && data && (unsigned)i0 < (unsigned)size.p[0] && (unsigned)(i1DataType<_Tp>::channels) < (unsigned)(size.p[1]channels()) && ((((sizeof(size_t)<<28)|0x8442211) >> ((DataType<_Tp>::depth) & ((1 << 3) - 1))*4) & 15) == elemSize1()) in cv::Mat::at, file D:\Ram\Software\OpenCV2.4.13\opencv\build\include\opencv2/core/mat.hpp, line 538

myfile << shape.part(i); //std::string num = std::to_string(shape.part(i)); for (int i = 0; i < 68; i++) { myfile << shape.part(i); /fwrite(num, 40, 1, fp);/

            }

How can I solve it

How do you set the color of given OpenCV point

I am using DLib, which is very similar to OpenCV. I would like to detect different parts ( lips , nose) etc with it. Can anyone help.

I'm trying to compile the webcam_face_pose_ex Dlib example on a 64 bit machine. All the linking libs are 32 bit. Thus it throws the error. I want to produce a 64 bit exe.

I'm trying to compile webcam_face_pose_ex.exe.

The program '[6968] webcam_face_pose_ex.exe' has exited with code -1073741701 (0xc000007b).

I am getting 0xc000007b ( the application was unable to start correctly). Click OK to close.

I changed the Code Generation option to Multi-threaded DLL (/MD). I'm still getting the same error.

For my project in visual studio, Multi-threaded Debug (/MTd) is set. So | am compiling with /MTd option.

In the solution explorer, the project has .cpp source files and I have some .lib files added to additional dependencies. The lib files are prebuilt opencv libs. Would I need to recompile the libs with different setting.

I just cleaned it and rebuilt it and changed the Runtime Library property value to /MTd. I get Error 1 error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MDd_DynamicDebug' doesn't match value 'MTd_StaticDebug' in webcam_face_pose_ex.obj D:\Ram\Projects\DLibCameraStream\dlib-19.0\examples\build\dlib.lib(entropy_decoder_kernel_2.obj).

I'm getting the following error,

Error 100 error LNK2038: mismatch detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value 'MDd_DynamicDebug' in webcam_face_pose_ex.obj D:\Ram\Projects\DLibCameraStream\dlib-19.0\examples\build\IlmImfd.lib(ImfFloatAttribute.obj) webcam_face_pose_ex

How can I solve it.

any further help?

or tell me where approximately I am making a mistake

Can u pls point me somewhere where I can get more info about using the ide correctly

Now I am getting

See answer

it shows the same...see the question..I'm running windows 10 64 bit

CamshiftDemo on 64 bit windows 10 doesn't display camera feed. How can i get the camera feed on screen.

I would like to add a screen shot here how can i do it

I tried running camshiftdemo.exe it throws 0x00007b

Can you tell me the exact location.All I see is 32 bit lib and binaries.

Where do i download 64 bit lib and dlls for OpenCV from

I am using Dlib & OpenCV for facial landmarking
