Here we use k-means clustering for color quantization. There is nothing new to be explained here. There are 3 features, say, R,G,B. So we need to reshape the image to an array of Mx3 size (M is number of pixels in image). And after the clustering, we apply centroid values (it is also R,G,B) to all pixels, such that resulting image will have ...

K-Means is an algorithm to detect clusters in a given set of points. It does this without you supervising or correcting the results. It works with any number of dimensions as well (that is, it works on a plane, 3D space, 4D space and any other finite dimensional spaces).

K-Means is an unsupervised algorithm from the machine learning approach. This algorithm tries to make clusters of input data features and is one ...

Jan 08, 2013 · Learn to use cv.kmeans() function in OpenCV for data clustering; Understanding Parameters Input parameters. samples: It should be of np.float32 data type, and each feature should be put in a single column. nclusters(K): Number of clusters required at end; criteria: It is the iteration termination criteria. When this criteria is satisfied ...

Here we are using an inbuild function(kmeans) available in cv2 for clustering pixels of our image. So, we can go through the arguments of cv2.
