摘要
分析常用的颜色空间中的色差公式,运用聚类算法将色差公式应用于图像背景主色提取.理论分析和实验结果均表明,CIELAB颜色空间中的CIE94色差公式具有较好的实验效果和较高的效率,说明色差公式的选择与实际使用情况紧密相连,要实现不同的图像显示效果,应选择不同的色差公式.
The most commonly used color difference formula was analyzed,the color difference formula was applied in image main color extraction by the clustering algorithm.Theoretical analysis and experimental results show that CIE94 has a better display,and more efficient.As a result,the choice of color difference formula is closely linked with the actual use.We should choose different color difference formula to achieve a different image display.
