Find the dominat color from the image
-
hai
i am able get the dominant color from image.but i am not able to get the parcentage of color.
this is my code get the dominant color from a imagecv::Matsource_img=cv::imread("detect.bmp",1); // Read image from path // Serialize, float cv::Mat data = source_img.reshape(1, source_img.total()); data.convertTo(data, CV_32F); // Perform k-Means int k = 10; std::vector<int> labels; cv::Mat3f centers; cv::kmeans(data, k, labels, cv::TermCriteria(), 1, cv::KMEANS_PP_CENTERS, centers); // Make a poster! (Clustering) for (int i = 0; i < (int)labels.size(); ++i) { data.at<float>(i, 0) = centers.at<float>(labels[i], 0); data.at<float>(i, 1) = centers.at<float>(labels[i], 1); data.at<float>(i, 2) = centers.at<float>(labels[i], 2); // qDebug()<<labels.size(); } // Un-Serialize, un-float cv::Mat destination = data.reshape(3, source_img.rows); destination.convertTo(source_img, CV_8UC3); std::sort(centers.begin(), centers.end(), [](const cv::Vec3f &a, const cv::Vec3f &b) -> bool { return a[0] + a[1] + a[2] > b[0] + b[1] + b[2]; } ); // Paint! QLabel *palette[6] = {ui->b_1, ui->b_2, ui->b_3, ui->b_4, ui->b_5, ui->b_6}; const int p = 0; // Offset for(int i = 0; i < 6; ++i) { // Set back color of label. Lazy ass way to show the colors std::stringstream back_clr; back_clr << centers.at<float>(i + p, 2) << "," << centers.at<float>(i + p, 1) << "," << centers.at<float>(i + p, 0); palette[i]->setStyleSheet(QString::fromStdString("background-color:rgb(" + back_clr.str() + ");")); qInfo()<< QString::fromStdString(back_clr.str() ); }
this my output:
"238.594,229.237,205.951"
"213.832,204.984,180.845"
"216.373,190.585,84.8002"
"218.931,132.845,105.804"
"138.95,143.804,118.714"
"198.743,110.853,46.7355"But i want the out put like this

Hi,
Do you mean the styling or the sorting ?
-
As you want to figure out the percentages, your OpenCV topic has nothing to do with Qt (or mobile or embedded systems).
-
Then you should check the OpenCV forum
