摘要
针对基于固定颜色集的直方图方法计算量与存储量过大,对亮度、噪声较敏感,参考颜色(reference co lortab le)方法受限于图像色彩分布的先验知识等弊端,提出了一种基于主颜色(dom a in co lor)的检索图像检索算法,在保持了较高的检索精度的同时,能够大大降低特征空间维度,提高检索性能。
In view of the limitation that the algorithm based on Reference Color Table has a large quantity of computation and storage, and is sensitive to luminosity and noise, and the weakness that the algorithm based on Fix Color Table is restricted to prior knowledge, the algorithm based on Domain Color is presented, which can greatly reduce the dimension of color feature, and keep high retrieval precision simultaneity.
