K-Means Clustering in OpenCV

Goal. 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, algorithm iteration stops.

Project Tutorial: Customer Segmentation Using K-Means Clustering

Learning Insight: StandardScaler transforms each feature to have a mean of 0 and a standard deviation of 1. This puts all features on an equal footing, regardless of their original scales. For K-means clustering, this is what ensures that each feature contributes equally to the distance calculations. Finding the Optimal Number of Clusters
