I want the picture to show on my screen like security_barrier_camera_demo

[Hung__Edwin]

HI 

I run segmentation_demo and the output picture out_0.bmp was produced to intel64/Release

I want  the picture to show on my screen like security_barrier_camera_demo 

How should I modify the code on segmentation_demo ??

Hi Edwin,

You should be able to modify the demo application to display the image instead of writing to a file. Try using the OpenCV function imshow instead of imwrite in the Python version of the demo. There may be additional changes required, give it a try and let me know the results. 

You can also take a look at the other demos and samples to see how the image is displayed.

Regards,

Jesus

Thanks reply

I used imshow on /intel/openvino/inference_engine_samples/segmentation_demo/main.cpp as below

  /** Dump resulting image **/
            std::string fileName = "out_" + std::to_string(image) + ".bmp";
            std::ofstream outFile(fileName, std::ofstream::binary);
            if (!outFile.is_open()) {
                throw std::logic_error("Can't open file : " + fileName);
            }
        cv::imshow("Detection results", outFile);    //show Detection results 
            writeOutputBmp(outArrayClasses, C, outFile);
            slog::info << "File : " << fileName << " was created" << slog::endl;

but can not build successful . The error message as below

/opt/intel/openvino/inference_engine/samples/segmentation_demo/main.cpp: In function ‘int main(int, char**)’:
/opt/intel/openvino/inference_engine/samples/segmentation_demo/main.cpp:277:3: error: ‘cv’ has not been declared
   cv::imshow("Detection results", outFile);

Hi Hung, Edwin,

The error seems related to cv not being declared in your program as the error suggests: /opt/intel/openvino/inference_engine/samples/segmentation_demo/main.cpp:277:3: error: ‘cv’ has not been declared.

I'd suggest to take a look at the main.cpp of the security_barrier_camera_demo and see how "cv" is declared and used throughout the code, this should give you a pretty good idea on how to incorporate the changes on your program.

Regards,

Luis
