| 摘 要： | 为提高图像检索性能，使用Harris彩色点提取器提取颜色特征点，设计一种基于颜色特征点的环形颜色直方图，在对图像进行Contourlet变换的基础上，提出Contourlet直方图的概念，改进其旋转不变性，并提取图像的纹理信息。仿真实验结果表明，该方法能够快速准确地检索彩色图像。

| Abstract: | To improve the quality of image retrieval, this paper uses Harris color point extractor to extract Color Points Of Interest(CPOI), and designs annular color histogram. Based on Contourlet transformation of images, texture information of images is extracted by using Contourlet histogram and the rotation invariance is improved. Simulation experimental results show this method can retrieve colorful images fastly and accurately. |
