INQUIRE: A Natural World Text-to-Image Retrieval Benchmark

1 code implementation4 Nov 2024 Edward Vendrow, Omiros Pantazis, Alexander Shepard, Gabriel Brostow, Kate E. Jones, Oisin Mac Aodha, Sara Beery, Grant van Horn

Detailed evaluation of a range of recent multimodal models demonstrates that INQUIRE poses a significant challenge, with the best models failing to achieve an mAP@50 above 50%.

SVL-Adapter: Self-Supervised Adapter for Vision-Language Pretrained Models

1 code implementation7 Oct 2022 Omiros Pantazis, Gabriel Brostow, Kate Jones, Oisin Mac Aodha

To combat this, a series of light-weight adaptation methods have been proposed to efficiently adapt such models when limited supervision is available.

Deep Blending for Free-Viewpoint Image-Based-Rendering

1 code implementation SIGGRAPH Asia 2018 2018 Peter Hedman, Julien Philip, True Price, Jan-Michael Frahm, George Drettakis, Gabriel Brostow

We present a new deep learning approach to blending for IBR, in which we use held-out real image data to learn blending weights to combine input photo contributions.
