Color quantization (CQ) is an important operation with various applications in medical image analysis. Most quantization methods are essentially based on data clustering algorithms. However, despite its popularity as a general purpose clustering algorithm, k-means has not received much respect in the CQ literature because of its high computational requirements and sensitivity to initialization. In this chapter, we investigate the performance of a recently proposed k-means based CQ method. Experiments on a diverse set of dermoscopy images of skin lesions demonstrate that an efficient implementation of k-means with an appropriate initialization strategy can in fact serve as a very effective color quantizer.
