【摘要】 介绍了HSV在低饱和度和低亮度时的色调奇异性,分析了HSV的色调奇异性对图像检索的影响。在此基础上,提出了基于多颜色空间的图像检索方法,奇异区域的像素点用YUV颜色空间表示,其他像素点用HSV颜色空间表示。实验表明,该算法在一定程度上克服了HSV的色调奇异性对图像检索的影响,提高了检索性能。更多还原

【Abstract】 The hue singularity of HSV and its influence on image retrieval under the low saturation and the low value were analyzed. In order to solve this problem, an image retrieval method based on multiple color space was presented: the pixels in the singular regions were expressed by YUV and the others by HSV. The experiments prove that this method can eliminate the influence on image retrieval caused by HSV hue singularity to a certain extent, and improve the retrieval performance.更多还原
