Efficient Diffusion on Region Manifolds: Recovering Small Objects with Compact CNN Representations
Ahmet Iscen, Giorgos Tolias, Yannis Avrithis +2
Query expansion is a popular method to improve the quality of image retrieval with both conventional and CNN representations. It has been so far limited to global image similarity.…
In the Saddle: Chasing Fast and Repeatable Features
Javier Aldana-Iuit, Dmytro Mishkin, Ondrej Chum +1
A novel similarity-covariant feature detector that extracts points whose neighbourhoods, when treated as a 3D intensity surface, have a saddle-like intensity profile. The saddle co…
Camera Elevation Estimation from a Single Mountain Landscape Photograph
Martin Cadik, Jan Vasicek, Michal Hradis +2
This work addresses the problem of camera elevation estimation from a single photograph in an outdoor environment. We introduce a new benchmark dataset of one-hundred thousand imag…
CNN Image Retrieval Learns from BoW: Unsupervised Fine-Tuning with Hard Examples
Filip Radenović, Giorgos Tolias, Ondřej Chum
Convolutional Neural Networks (CNNs) achieve state-of-the-art performance in many computer vision tasks. However, this achievement is preceded by extreme manual annotation in order…
