Improving the matching of deformable objects by learning to detect keypoints

1 code implementation1 Sep 2023 Felipe Cadar, Welerson Melo, Vaishnavi Kanagasabapathi, Guilherme Potje, Renato Martins, Erickson R. Nascimento

We propose a novel learned keypoint detection method to increase the number of correct matches for the task of non-rigid image correspondence.

Encyclopedic VQA: Visual questions about detailed properties of fine-grained categories

1 code implementation ICCV 2023 Thomas Mensink, Jasper Uijlings, Lluis Castrejon, Arushi Goel, Felipe Cadar, Howard Zhou, Fei Sha, André Araujo, Vittorio Ferrari

Empirically, we show that our dataset poses a hard challenge for large vision+language models as they perform poorly on our dataset: PaLI [14] is state-of-the-art on OK-VQA [37], yet it only achieves 13. 0% accuracy on our dataset.

Learning to Detect Good Keypoints to Match Non-Rigid Objects in RGB Images

1 code implementation13 Dec 2022 Welerson Melo, Guilherme Potje, Felipe Cadar, Renato Martins, Erickson R. Nascimento

We present a novel learned keypoint detection method designed to maximize the number of correct matches for the task of non-rigid image correspondence.

Learning Geodesic-Aware Local Features from RGB-D Images

no code implementations22 Mar 2022 Guilherme Potje, Renato Martins, Felipe Cadar, Erickson R. Nascimento

Most of the existing handcrafted and learning-based local descriptors are still at best approximately invariant to affine image transformations, often disregarding deformable surfaces.

Extracting Deformation-Aware Local Features by Learning to Deform

1 code implementation NeurIPS 2021 Guilherme Potje, Renato Martins, Felipe Cadar, Erickson R. Nascimento

Despite the advances in extracting local features achieved by handcrafted and learning-based descriptors, they are still limited by the lack of invariance to non-rigid transformations.
