Quantization and Classification using K-Means Clustering
by Sara Wendte
Introduction
K-means clustering is a simple unsupervised learning method. This method can be applied to implement color quantization in an image by finding clusters of pixel values. Another useful application would be automatic classification of phonemes in a speech signal by finding clusters of formant values for different speakers.
