基于球颜色模型的主色调提取与颜色名标注

EXTACTING MAIN COLORS BASED ON SPHERICAL COLOR MODEL AND ANNOTATING WITH COLOR NAMES

将对立色的颜色空间距离设为1,建立了一种球颜色模型,利用该颜色模型统计图像像素的三维颜色直方图,利用极大值法提取图像的主色调；对1 031个中文颜色名的HVC值转换为该颜色模型值,利用最接近的中文颜色名描述图像的主色调,实现了对图像主色调的颜色名标注.

A spherical color model is set up on the assumption that the maximal distance between any two opposite colors is 1. The main colors of an image are extracted by searching the colors related to the top values of 3 direction histgram of the colors of the image in the new color model. The HVC values of 1 031 chinese color names are transformed to the HSY values of the new color model so that the main colors are annotated with some proper chinese names which are most closed to in the new color model
