| 摘 要： | 综合二维典型相关分析和相关反馈的图像检索方法,首先利用颜色直方图法对样本图像进行初步检索,接着手工标注用户满意的图像作为正样本,其余的作为负样本.利用正负样本的颜色分块特征训练图像分类器,通过训练好的分类器对图像进行进一步检索.实验证明,我们的方法在目标不太明确的情况下,通过相关反馈操作的检索性能会获得一定的提升.

| Abstract: | We present the image retrieval system integrating 2DCCA with relevance feedback in this paper.An initial retrieval is performed using color histogram and then the satisfying images are manually marked as the positive samples leaving the rest as the negative ones.The images are further retrieved by the classifier which is learned with the color block feature of the samples.Experimental results illustrate that the retrieval performance is promoted to some extent by means of relevance feedback scheme in the situation that no evident objects are in the images. |
