基于感兴趣区域的图像自动标注算法研究

Automatic image annotation algorithm based on the region of interest of the image

提出一种基于感兴趣区域(ROI)的图像自动标注算法.首先利用JPEG 2000中的Maxshift算法提取出图像的感兴趣区域,建立感兴趣图像库;之后对图像库中的图像利用SIFT算法提取图像的特征向量;并利用支持向量机对图像进行标注;最后应用Corel图像数据库进行自动标注仿真试验,结果表明,所设计算法有较好的效果.

For improving the accuracy of image automatic annotation, the paper submits a new automatic annota- tion algorithm based on the region of interest （ROI） of the image. First, it extracts the region of interest of the image by using the Maxshift algorithm of JPEG 2000, thereby establishing a ROI library, and then extracts the feature vector by using SIFT algorithm in the image library, and SVM is adopted to classify and annotate images automatically. Experimental results on images from Corel database show that this algorithm can improve the anno- tation accuracy.
