What's Holding Back Latent Visual Reasoning?
André G. Viveiros, Nuno Gonçalves, André F. T. Martins +1
Humans can approach complex visual problems by mentally simulating intermediate visual steps, rather than reasoning through language alone. Inspired by this, several works on Visio…
LanteRn: Latent Visual Structured Reasoning
André G. Viveiros, Nuno Gonçalves, Matthias Lindemann +1
While language reasoning models excel in many tasks, visual reasoning remains challenging for current large multimodal models (LMMs). As a result, most LMMs default to verbalizing…
Geometric implicit neural representations for signed distance functions
Luiz Schirmer, Tiago Novello, VinÃcius da Silva +5
\textit{Implicit neural representations} (INRs) have emerged as a promising framework for representing signals in low-dimensional spaces. This survey reviews the existing literatur…
FLOWING: Implicit Neural Flows for Structure-Preserving Morphing
Arthur Bizzi, Matias Grynberg, Vitor Matias +7
Morphing is a long-standing problem in vision and computer graphics, requiring a time-dependent warping for feature alignment and a blending for smooth interpolation. Recently, mul…
VOIDFace: A Privacy-Preserving Multi-Network Face Recognition With Enhanced Security
Ajnas Muhammed, Iurri Medvedev, Nuno Gonçalves
Advancement of machine learning techniques, combined with the availability of large-scale datasets, has significantly improved the accuracy and efficiency of facial recognition. Mo…
