Color Quantization Using the Fast K-Means Algorithm

摘要

Many color images use 24 bits for color information. However, this number of colors is not always necessary. In This paper, an algorithm that quantizes a full-color image From about 17 million to 256 colors is proposed. The Quantized colors are calculated so that the sum of squared Quantization errors is minimized. To quantize the color Image, the fast K-means algorithm is proposed. This algo- Rithm classifies K clusters into groups.
