In image-based three-dimensional (3-D) reconstruction, one topic of growing importance is how to quickly obtain a 3-D model from a large number of images. The retrieval of the correct and relevant images for the model poses a considerable technological challenge. The “image vocabulary tree” has been proposed as a method to search for similar images. However, a significant drawback of this approach is identified in its low time efficiency and barely satisfactory classification result. The method… CONTINUE READING

  • For each set of experimental data, the recall is about 10% higher than that of both the traditional method and the method of improved vocabulary tree without losing too much precision as shown in Fig.
