| 摘 要： | 提出了一种基于图像颜色直方图及纹理特征提取的兴趣点凸包检索方法。首先利用Harris角点检测器检测图像的兴趣点,然后利用正负划分性算法求取兴趣点集合的凸包,确定图像的感兴趣区域,最后计算感兴趣区域的颜色直方图和灰度共生矩阵作为图像特征进行图像检索。在图像检索过程中,保证了图像旋转、平移、尺度不变性。通过对10类1000幅图像进行检索,实验表明该方法与其它基于兴趣点凸包的检索方法相比,提高了图像检索的平均查准率和查全率,可以更准确地查找到用户所需图像。

| Abstract: | This paper proposes a new convex hull of interest points retrieval method which based on Color histogram and Texture feature.Firstly, theinterest points are detected by Harris' corner detector.Then convex hull of interest points is calculated recursively by plus or minus Characteristic ofDemarcatio and image region of interest is determined. Finally, this paper calculate color histogram and gray level co-occurrence martrix which as image features to carry out retrieval.ln the process of image retrival,To en... |
