Flexible visual prompts for in-context learning in computer vision

1 code implementation11 Dec 2023 Thomas Foster, Ioana Croitoru, Robert Dorfman, Christoffer Edlund, Thomas Varsavsky, Jon Almazán

Additionally, we propose a technique for support set selection, which involves choosing the most relevant images to include in this set.

Moment Detection in Long Tutorial Videos

1 code implementation ICCV 2023 Ioana Croitoru, Simion-Vlad Bogolin, Samuel Albanie, Yang Liu, Zhaowen Wang, Seunghyun Yoon, Franck Dernoncourt, Hailin Jin, Trung Bui

To study this problem, we propose the first dataset of untrimmed, long-form tutorial videos for the task of Moment Detection called the Behance Moment Detection (BMD) dataset.

Cross Modal Retrieval with Querybank Normalisation

1 code implementation CVPR 2022 Simion-Vlad Bogolin, Ioana Croitoru, Hailin Jin, Yang Liu, Samuel Albanie

In this work we first show that, despite their effectiveness, state-of-the-art joint embeddings suffer significantly from the longstanding "hubness problem" in which a small number of gallery embeddings form the nearest neighbours of many queries.

TEACHTEXT: CrossModal Generalized Distillation for Text-Video Retrieval

1 code implementation ICCV 2021 Ioana Croitoru, Simion-Vlad Bogolin, Marius Leordeanu, Hailin Jin, Andrew Zisserman, Samuel Albanie, Yang Liu

In recent years, considerable progress on the task of text-video retrieval has been achieved by leveraging large-scale pretraining on visual and audio datasets to construct powerful video encoders.

Unsupervised learning of foreground object detection

no code implementations14 Aug 2018 Ioana Croitoru, Simion-Vlad Bogolin, Marius Leordeanu

We train a student deep network to predict the output of a teacher pathway that performs unsupervised object discovery in videos or large image collections.

Unsupervised learning from video to detect foreground objects in single images

no code implementations ICCV 2017 Ioana Croitoru, Simion-Vlad Bogolin, Marius Leordeanu

Our approach is different from the published literature that performs unsupervised discovery in videos or in collections of images at test time.
