Abstract
Fuzzy C-Means (FCM) algorithm is an important color quantization technology. Though it is widely used, its runtime is long and its quantization result is not good enough. In the paper, a spatial FCM color quantization algorithm which uses pyramid data structure for the hierarchical analysis of a color image is proposed. Experiments show that the algorithm has better quantization result and shorter runtime than the conventional FCM algorithm and the spatial FCM algorithm before.
