A New Spatial Weighting Scheme for Bag-of-Visual-Words Ismail Elsayad, Jean Martinet, Thierry Urruty, Chabane Djeraba LIFL/CNRS-UMR 8022 University of Lille 1 Lille, France {ismail.elsayad, jean.martinet, thierry.urruty, chabane.djeraba}@li?.fr Abstract In this paper, we develop a novel...
With this in mind, we propose a teacher-student scheme to learn representations by training a convolutional net to reconstruct a bag-of-visual-words (BoW) representation of an image, given as input a perturbed version of that same image. Our strategy performs an online training of both the ...
Scene recognition is an important and challenging problem in computer vision. One of the most used scene recognition methods is the bag-of-visual words. Despite the interesting results, this approach does not capture the detail richness of spatial information of the visual words on the image. In...
, object retrieval has progressed significantly in the past years and has already found deployment in real-life applications and products, but the traditional BoVW methods have several problems, such as:low time efficiency and large memory consumption, the synonymy and polysemy of visual words. ...
We investigate bag-of-visual-words (BOVW) approaches to land-use classification in high-resolution overhead imagery. We consider a standard non-spatial representation in which the frequencies but not the locations of quantized image features are used to discriminate between classes analogous to how ...
The objective of this work is to reconstruct an original image from Bag-of-Visual-Words (BoVW). Image reconstruction from features can be a means of identifying the characteristics of features. Additionally, it enables us to generate novel images via features. Although BoVW is the de facto ...

Bag of visual words (BoVW) can do well in selecting feature in geographical scene classification; nevertheless, it works effectively only if the provided feature extractor is well-matched. In this paper, we use convolutional neural networks (CNNs) for optimizing proposed feature extractor, so that...
The Bag-Of-Visual-Words (BOVW) paradigm is fast becoming a popular image representation for Content-Based Image Retrieval (CBIR), mainly because of its better retrieval effectiveness over global feature representations on collections with images being near-duplicate to queries. In this experimental stu...
