基于边缘颜色分布的图像检索方法

Image retrieval algorithm based on edge color distribution

提出了一种新的基于边缘颜色分布的图像检索算法。该算法将不同类型边缘附近的颜色分布作为刻画图像内容的主要特征,设计了一种紧凑的2D边缘颜色直方图来对图像的边缘颜色分布特征进行描述,既利用了局部颜色特征,又考虑了不同类型边缘的空间分布信息,克服了传统颜色直方图不能反映空间信息的缺陷。实验结果表明,该算法与其他同类方法相比,有效地提高了检索性能。

A new image retrieval algorithm based on edge color distribution was proposed. The content information of an image was characterized by color distribution of different edge types described by two-dimension edge color histogram. The algorithm takes not only the local color features into account but also the space distribution information of edge types and overcomes the shortcoming of color histogram which loses the location information. Experimental results show that this method effectively improves the image retrieval performance compared with other retrieval methods.
