基于局部对角色差描述符的图像检索方法
Image Retrieval Method Based on Local Diagonal Color Difference Descriptor
摘要
Abstract
For retrieval accuracy of Text-based Image Retrieval(TBIR)method is not high,this paper proposes a new image retrieval method.The hue and saturation components are reasonably quantified in HSV color space to make more detailed description for color difference.Local Diagonal Color Difference(LDCD)descriptor is extracted on the luminance component to reveal the spatial distribution information of color.Composite color feature and color spatial distribution information are retrieved,which solves the problem that color histogram cannot describe the color spatial distribution information.Experimental results show that this method can achieve higher retrieval accuracy and reduce the time required for image retrieval by selecting the Corel image database.关键词
