Label Propagation for Zero-shot Classification with Vision-Language Models

2 code implementations5 Apr 2024 Vladan Stojnić, Yannis Kalantidis, Giorgos Tolias

We leverage the graph structure of the unlabeled data and introduce ZLaP, a method based on label propagation (LP) that utilizes geodesic distances for classification.

Training Ensembles with Inliers and Outliers for Semi-supervised Active Learning

1 code implementation7 Jul 2023 Vladan Stojnić, Zakaria Laskar, Giorgos Tolias

In this work, we present an approach that leverages three highly synergistic components, which are identified as key ingredients: joint classifier training with inliers and outliers, semi-supervised learning through pseudo-labeling, and model ensembling.

Do we still need ImageNet pre-training in remote sensing scene classification?

1 code implementation5 Nov 2021 Vladimir Risojević, Vladan Stojnić

Recently, the availability of larger high resolution remote sensing (HRRS) image datasets and progress in self-supervised learning have brought up the questions of whether supervised ImageNet pre-training is still necessary for remote sensing scene classification and would supervised pre-training on HRRS image datasets or self-supervised pre-training on ImageNet achieve better results on target remote sensing scene classification tasks.

Self-Supervised Learning of Remote Sensing Scene Representations Using Contrastive Multiview Coding

1 code implementation14 Apr 2021 Vladan Stojnić, Vladimir Risojević

We show that, for the downstream task of remote sensing image classification, using self-supervised pre-training on remote sensing images can give better results than using supervised pre-training on images of natural scenes.

A Method for Detection of Small Moving Objects in UAV Videos

1 code implementation11 Feb 2021 Vladan Stojnić, Vladimir Risojević, Mario Muštra, Vedran Jovanović, Janja Filipi, Nikola Kezić, and Zdenka Babić

To circumvent this problem, we propose training a CNN using synthetic videos generated by adding small blob-like objects to video sequences with real-world backgrounds.
