针对传统的GVP(Geometry-Preserving Visual Phrases)图像检索算法计算量大、时间复杂度高且不适合处理大规模图像检索等缺点,文章提出了FSF-GVP(Frequency Statistics Feature-Geometry-Preserving Visual Phrases)算法,该方法将词频统计特征和GVP算法相结合,使用GVP排序算法对词频特征统计后的相似结果集进行排序,忽略不相似结果集,极大地提高了检索效率。实验结果表明,FSF-GVP在保证检索准确性的前提下,提高了检索效率,适用于实时大规模图像检索。
針對傳統的GVP(Geometry-Preserving Visual Phrases)圖像檢索算法計算量大、時間複雜度高且不適閤處理大規模圖像檢索等缺點,文章提齣瞭FSF-GVP(Frequency Statistics Feature-Geometry-Preserving Visual Phrases)算法,該方法將詞頻統計特徵和GVP算法相結閤,使用GVP排序算法對詞頻特徵統計後的相似結果集進行排序,忽略不相似結果集,極大地提高瞭檢索效率。實驗結果錶明,FSF-GVP在保證檢索準確性的前提下,提高瞭檢索效率,適用于實時大規模圖像檢索。

Traditional GVP (geometry-preserving visual phrases) image retrieval algorithm is not suitable for handling the large-scale image retrieval because of its high time complexity. In this paper, FSF-GVP (frequency statistics feature-geometry-preserving visual phrases) algorithm, which combined word frequency statistic characteristics and GVP algorithm, was proposed. FSF-GVP algorithm counts visual word frequency characteristics of an image to be searched and image database to get similar result set and dissimilar result set. Then FSF-GVP algorithm uses the GVP algorithm to sort the similar result set, which improves the retrieval efifciency. The experiment results on Oxford 5K dataset show that FSF-GVP is suitable for the large-scale real-time image retrieval on the premise of ensuring the accuracy of retrieving result and improving the retrieval efifciency.
