反馈日志隐含的图像语义信息有助于图像自动标注,但日志数据中存在的噪声、片面性等问题制约了其作用,故提出基于日志的协同图像自动标注算法。根据日志获取的特点,采用增量关联规则挖掘处理日志信息去除其噪声,利用协同滤波思想扩展图像标注词数量,利用WordNet得到标注词间关系,并结合图像底层特征利用混合概率模型实现图像自动标注。在Corel5K和互联网数据集上的实验表明:该算法降低了日志噪声及片面性所带来的影响,提高了图像自动标注效率和质量。
反饋日誌隱含的圖像語義信息有助于圖像自動標註,但日誌數據中存在的譟聲、片麵性等問題製約瞭其作用,故提齣基于日誌的協同圖像自動標註算法。根據日誌穫取的特點,採用增量關聯規則挖掘處理日誌信息去除其譟聲,利用協同濾波思想擴展圖像標註詞數量,利用WordNet得到標註詞間關繫,併結閤圖像底層特徵利用混閤概率模型實現圖像自動標註。在Corel5K和互聯網數據集上的實驗錶明:該算法降低瞭日誌譟聲及片麵性所帶來的影響,提高瞭圖像自動標註效率和質量。

The potential image semantic information in feedback logs helps to improve the quality of image automatic anno-tation, but the noisy and one-sidedness of the log restrict its function. So it proposes a log-based collaborative automatic image annotation algorithm. It uses incremental association rule to mine log messages according to its characteristics to remove the noisy data and expand the amount of image annotation words with the thought of collaborative filtering. Com-bining the relationship of the annotation words from the WordNet and the low-level image features, it can accomplish image automatic annotation with adoption of hybrid probabilistic model. The experimental results based on Corel5K and Internet image set show that the proposed algorithm can reduce the negative effects from noisy and one-sidedness of the log data, and improve the performance and efficiency of the automatic image annotation.
