Object-Guided Day-Night Visual Localization in Urban Scenes

Assia Benbihi, Cédric Pradalier, Ondřej Chum

We introduce Object-Guided Localization (OGuL) based on a novel method of local-feature matching. Direct matching of local features is sensitive to significant changes in illuminat…

Graph convolutional networks for learning with few clean and many noisy labels

Ahmet Iscen, Giorgos Tolias, Yannis Avrithis +2

In this work we consider the problem of learning a classifier from noisy labels when a few clean labeled examples are given. The structure of clean and noisy data is modeled by a g…

Targeted Mismatch Adversarial Attack: Query with a Flower to Retrieve the Tower

Giorgos Tolias, Filip Radenovic, Ondřej Chum

Access to online visual search engines implies sharing of private user content - the query images. We introduce the concept of targeted mismatch attack for deep learning based retr…

No Fear of the Dark: Image Retrieval under Varying Illumination Conditions

Tomas Jenicek, Ondřej Chum

Image retrieval under varying illumination conditions, such as day and night images, is addressed by image preprocessing, both hand-crafted and learned. Prior to extracting image d…
