Content-based Saliency Region PartialDuplicate Image Retrieval Relative Saliency Ordering Constraint
2013/7/24
In traditional partial-duplicate image retrieval, imagesare commonly represented using the Bag-of-Visual-Words(BOV) model built from image local features, such as SIFT.Actually, there is only a small ...
Modeling spatial and semantic cues for large-scale near-duplicated image retrieval
And–Or graph face fusion gender conversion
2013/7/24
Bag-of-visual Words (BoW) image representation has been illustrated as one of the most promising solutions for large-scale near-duplicatedimageretrieval. However, the traditional visual vocabulary is ...
