碩士 === 國立高雄第一科技大學 === 電腦與通訊工程所 === 97 === In this thesis, color image quantization based on various color spaces are investigated.First, several color space representations are described including RGB, YCbCr , HSI and CMY spaces etc. Then, three color quantization algorithms are presented including Median-Cut algorithm, K-Means algorithm and Fuzzy C-means algorithm. Next, the peak signal-to-noise ratio (SNR) is used to evaluate the performance of three color quantization algorithms in various color spaces. Finally, experimental results are conducted to demonstrate the effectiveness of three color quantization algorithms by using various images.
