While image retrieval and instance recognition techniques are progressing rapidly, there is a
need for challenging datasets to accurately measure their performance--while posing novel …

Is it possible to determine the location of a photo from just its pixels? While the general
problem seems exceptionally difficult, photos often contain cues such as landmarks, weather …

Recently developed Structure from Motion (SfM) reconstruction approaches enable the
creation of large scale 3D models of urban scenes. These compact scene representations …

To reliably determine the camera pose of an image relative to a 3D point cloud of a scene,
correspondences between 2D features and 3D points are needed. Recent work has …

We propose a powerful pipeline for determining the pose of a query image relative to a point
cloud reconstruction of a large scene consisting of more than one million 3D points. The key …

Visual localization, ie, camera pose estimation in a known scene, is a core component of
technologies such as autonomous driving and augmented reality. State-of-the-art …

This paper considers a family of metrics to compare images based on their local descriptors.
It encompasses the vector or locally aggregated descriptors descriptor and matching …

While the successful estimation of a photo's geolocation enables a number of interesting
applications, it is also a very challenging task. Due to the complexity of the problem, most …

Retrieving videos from large repositories using image queries is important for many
applications, such as brand monitoring or content linking. We introduce a new retrieval …
