KMeansDemo

A simple program to show how OpenCV's KMeans works displaying its visual output in "real time". This code is part of a post on my blog about KMeans.

How to use

You will need a working OpenCV compilation. To learn how to install and use it with Eclipse & MinGW-w64 take a look in a post on my blog.

This project was developed using Eclipse. Therefore, clone using git clone or download and open it as a Project then configure the Linker and Compiler to match your OpenCV folder.

For compiling with G++ (Considering the OpenCV 3.4 and folders C:\opencv\install\include & C:\opencv\install\x64\mingw\lib):

• git clone

• cd KMeansDemo\src

• g++ "-IC:\\opencv\\install\\include" -O0 -g3 -Wall -c -fmessage-length=0 -o "src\\KMeansDemo.o" "..\\src\\KMeansDemo.cpp"

• g++ "-LC:\\opencv\\install\\x64\\mingw\\lib" -o KMeansDemo.exe "src\\KMeansDemo.o" -lopencv_core340 -lopencv_highgui340 -lopencv_imgcodecs340 -lopencv_imgproc340

• .\KMeansDemo

• Insert the name of the image you want to see being processed by cv::kmeans() and choose the number of clusters using the Trackbar on top.
