kmeans clustering convert code to python
I have the following code for k-means clustering , but it is in C++ . I need it in python. I was able to convert just the k-means clustering part into python. Can someone please convert the part where I access the labels and regenerate the image with just the colors into python as soon as possible. Thanks a lot in advance.
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
void main(void)
{
Mat img=imread("14780105241945453.png",IMREAD_COLOR);
cout << "Pixels "<<img.rows*img.cols<<"\n";
Mat src,srcF;
cvtColor(img, src, CV_BGR2Lab);
src.convertTo(srcF, CV_32FC3);
cout << "Pixels " << srcF.rows*srcF.cols << "\n";
vector<Vec3f> plan;
plan.assign((Vec3f*)srcF.datastart, (Vec3f*)srcF.dataend);
cout << "Pixels " << plan.size() << "\n";
int clusterCount = 3;
Mat labels;
Mat centers;
kmeans(plan, clusterCount,labels,TermCriteria(TermCriteria::EPS + TermCriteria::COUNT, 10, 1.0), 3, KMEANS_PP_CENTERS, centers);
Mat mask;
namedWindow("Original", WINDOW_NORMAL);
imshow("Original", img);
int maxCluster=0,ind=-1;
for (int i = 0; i < clusterCount; i++)
{
cv::Mat cloud = (labels == i) ;
namedWindow(format("Cluster %d",i), WINDOW_NORMAL);
Mat result = Mat::zeros(img.rows, img.cols, CV_8UC3);
if (cloud.isContinuous())
mask = cloud.reshape(0, img.rows);
else
cout << "error";
int m=countNonZero(mask);
if (m > maxCluster)
{
maxCluster = m;
ind=i;
}
img.copyTo(result, mask);
imshow(format("Cluster %d", i), result);
imwrite(format("Cluster%d.png", i), result);
}
cout<<"Cluster max is "<<ind<<" with "<<maxCluster<<" pixels";
waitKey();
}
Please help me. Thanks a lot in advance and as soon as possible.
May be you start translate this (or my) code in python and come back with a real problem?
