W-Tree Indexing for Fast Visual Word Generation Abstract?W-Tree Indexing for Fast Visual Word Generation. The bag-of-visual-words representation has been widely used in image retrieval and visual recognition. The most time-consuming step in obtaining this representation is the visual word generation, i.e., assigning visual words to the corresponding local features in a high-dimensional space. Recently, structures…
