In visual studio we have option of Start Debugging the opencv program by pressing F5. According to my task, If I press any key(for example when I press key 'A', the program has to start executing) in the keyboard, the program has to start his execution. Can anyone share their ideas to accomplish this task. Is it possible to implement Keyboard Event Handler in opencv program

Thanks

@StevenPuttemans, @Lorena GdL: Thanks to both of you for your time. I dont want the pixel values, I need images to be saved on the excel. Currently I'm working on the automation(with the help of Template Matching- reading two images and comparing it and need to say whether they are equal or not)of automotive related test cases and the test cases output are the images. I want to save those images in an excel. Moreover my next task is I want to read images (both template image(column A in excel) and source image(column B)) from excel sheet and save the output in column c in excel sheet.Do you have any idea on this. If you have please help me.

Hi All, I'm working on Template matching program using OpenCV . I want to save the Result image in an excel sheet. How to call a excel sheet from a opencv program?

Thanks, Manimaran

@Balaji, Thanks for your link. Is this code is for one template image. And float Threshold and float Closeness,do I need to give the value ? I tried by giving the value , i got an error. can you please help me. If you share your email id ,so that I will send my source image and template image,which will be easy for you to understand my problem.

since I'm not able to paste the complete code in a single comment.I will paste it in two halves..sory for the inconvience. code continues, while (true) { double minval, maxval, threshold = 0.9; Point minloc, maxloc; minMaxLoc(res, &minval, &maxval, &minloc, &maxloc);

    if (maxval >= threshold)
    {
      rectangle(srcimg, maxloc, Point(maxloc.x + tmplimg.cols, maxloc.y + tmplimg.rows), CV_RGB(0,255,0), 2);
      floodFill(res, maxloc, Scalar(0), 0, Scalar(.1), Scalar(1.));

      printf("My current maxval: %f \n", maxval);
    }
    else    
        break;
}

imshow("Source Image", srcimg);
waitKey();
return 0;

}

Hi Balaji, I am working on Template Matching using Opencv. I have written the template matching program for one template image and its working fine.. Now i'm trying template matching with multiple template images. I tried your code for multiple template but its not working for me..I dont know the reason. When I studied your code I had few doubts, can you please clarify my doubts 1.Img_Scene_Bgr and Img_Template_Bgr are the gray values of the source and template images? 2. In this line, cv::matchTemplate(Img_Template_Bgr, Img_Scene_Bgr, Img_Result_Float, CV_TM_CCOEFF_NORMED); when I checked in the opencv tutorial for the matchtemplate format, inside the bracket first we have declare the source image and then oly template image..you did in the other way.

@Sharath, Thanks Sharath for your reference. It would be great if you share your email id or contact details if you dont mind ,so that i contact via email. I'm just going through the link which you have shared and let me try..The link which you have shared is for the offline template matching..Actually I have to do template matching for a live video...Actually i tried to incorporate the webcam for the live video but its not working.. I think you have done template matching for the live video..can you please help me on that. Once again i would like to thank you for the link. Regards, Manimaran

Hi Sharath, I have one more question in addition to the above one. How did you gave Multiple Template images in template matching. Can you please explain how to give my multiple template images. Thanks, Manimaran

Hi, with the help of the link you posted ,I have written code for offline scenario. Currently I am working on Online scenarios which means I'm getting input from the webcam for the source image and matching with the template image which is offline one. Please help me on this.Thanks

Hi, I am new to OpenCV. I am working on Image processing task where I need to match template image with the source image where source image is the input from webcam. I have written code for offline template matching and I dont know to proceed for online scenario. Could someone please help me to complete this task.

Thanks, Manimaran

Hi Sharath, I am also working on the similar kind of scenario. I am new to OpenCV and I dont know how to proceed. I have already written code for the offline template matching. Its working fine. Now I want to do template matching in a live video. Could you please help me to complete the task. It would be great if you share your complete code so that I will get an idea and I can proceed. Thanks, Manimaran

Hi, I am also working on the similar kind of scenario. I want to perform template matching by having source image input from webcam and match with a template image. I am new to OpenCV. Could you please help me in this.
