摘　　要：图像彩色化处理通常遵循颜色的局部相似性原则,选择适当的颜色空间是其重要问题。以能否实现颜色的亮度与色度分离为依据,将常用颜色空间分为颜色构成空间和颜色属性空间。考察了不同颜色空间中颜色分布的光滑程度,评估了各颜色空间在彩色化处理中的适用性。理论和实验结果表明,颜色属性空间更适用于彩色化处理。结合对彩色化本质的分析,引出了有关颜色空间选择的若干结论。Local color similarity is the basis of image colorization,where choosing the suitable color space is a key problem. According to the standard whether luminance and chrominance could be separated from each other, common color spaces were divided into two categories, i. e. color-component space and color-attribute space. Smoothness of color distri- bution differs in different color spaces. The applicability of different color spaces in colorization was evaluated. Theoretic and experimental results show that color-attribute space is more appropriate to use in colorization. Furthermore some conclusions on color space selection are drawn by analyzing the essence of colorization.
