Co-Segmentation without any Pixel-level Supervision with Application to Large-Scale Sketch Classification

Nikolaos-Antonios Ypsilantis, Ondřej Chum

This work proposes a novel method for object co-segmentation, i.e. pixel-level localization of a common object in a set of images, that uses no pixel-level supervision for training…

Crafting Distribution Shifts for Validation and Training in Single Source Domain Generalization

Nikos Efthymiadis, Giorgos Tolias, Ondřej Chum

Single-source domain generalization attempts to learn a model on a source domain and deploy it to unseen target domains. Limiting access only to source domain data imposes two key…
