    Improving Image Pair Selection for Large Scale Structure from Motion by Introducing Modified Simpson Coefficient

  • Original language description

    Selecting visually overlapping image pairs without any prior information is an essential task of large-scale structure from motion (SfM) pipelines. To address this problem, many state-of-the-art image re trieval systems adopt the idea of bag of visual words (BoVW) for com puting image-pair similarity. In this paper, we present a method for im proving the image pair selection using BoVW. Our method combines a conventional vector-based approach and a set-based approach. For the set similarity, we introduce a modified version of the Simpson (m-Simpson) coefficient. We show the advantage of this measure over three typical set similarity measures and demonstrate that the combination of vector similar ity and the m-Simpson coefficient effectively reduces false positives and in creases accuracy. To discuss the choice of vocabulary construction, we pre pared both a sampled vocabulary on an evaluation dataset and a basic pre trained vocabulary on a training dataset. In addition, we tested our method on vocabularies of different sizes. Our experimental results show that the proposed method dramatically improves precision scores especially on the sampled vocabulary and performs better than the state-of-the-art methods that use pre-trained vocabularies. We further introduce a method to deter mine the k value of top-k relevant searches for each image and show that it obtains higher precision at the same recall.
