2015-02-10 01:49:08 -0600	asked a question	Getting masked area to be transparent ? So far i have managed to use masks and get the second image from the first. But what i want is the black area in second image to be transparent (i.e the output i an trying to get is the third image) Here is the code so far. Please advice me on this. //imwrite parameters compression_params.push_back(CV_IMWRITE_JPEG_QUALITY); compression_params.push_back(100); //reading image to be masked image = imread(main_img, -1); //CV_LOAD_IMAGE_COLOR namedWindow("output", WINDOW_NORMAL); //imshow("output", image); //Creating mask image with same size as original image Mat mask(image.rows, image.cols, CV_8UC1, Scalar(0)); // Create Polygon from vertices ROI_Vertices.push_back(Point2f(float(3112),float(58))); ROI_Vertices.push_back(Point2f(float(3515),float(58))); ROI_Vertices.push_back(Point2f(float(3515),float(1332))); ROI_Vertices.push_back(Point2f(float(3112),float(958))); approxPolyDP(ROI_Vertices, ROI_Poly, 1, true); // Fill polygon white fillConvexPoly(mask, &ROI_Poly[0] , ROI_Poly.size(), 255, 8, 0); //imshow("output", mask); // Create new image for result storage imageDest = cvCreateMat(image.rows, image.cols, CV_8UC4); // Cut out ROI and store it in imageDest image.copyTo(imageDest, mask); imwrite("masked.jpeg", imageDest, compression_params); imshow("output", imageDest); cvWaitKey(0);
2015-01-27 04:27:20 -0600	commented question	error C2248: 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' Thank you very much. I'll try that. :)
2015-01-27 03:13:13 -0600	commented question	error C2248: 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' Thank you for your comments. Lines 146 gives the error. `classes_classifiers[class_].train(samples_32f,labels);` I didn't know about `void glob(string dirname, vector<string> files); I'll look into that.
2015-01-27 01:36:50 -0600	asked a question	error C2248: 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' I am trying to use bag of features model and train and SVM. I am using this tutorial and this sample code. I am using Windows 8 and OpenCV 2.4.10. I am running this on Visual Studio 2012. But i am continuously getting this error 'CvSVM::CvSVM' : cannot access private member declared in class 'CvSVM' I tried using OpenCV 2.4.9 but same error is still there. I searched a lot for this and still could not find a proper solution for this. Please help me on this. Thanks in advance. Below is the code. I am using this Dirent API for Microsoft Visual Studio as well.
