Moving Frame Net: SE(3)-Equivariant Network for Volumes

1 code implementation7 Nov 2022 Mateus Sangalli, Samy Blusseau, Santiago Velasco-Forero, Jesus Angulo

Equivariance of neural networks to transformations helps to improve their performance and reduce generalization error in computer vision tasks, as they apply to datasets presenting symmetries (e. g. scalings, rotations, translations).

Scale Equivariant U-Net

no code implementations10 Oct 2022 Mateus Sangalli, Samy Blusseau, Santiago Velasco-Forero, Jesus Angulo

Therefore, this paper introduces the Scale Equivariant U-Net (SEU-Net), a U-Net that is made approximately equivariant to a semigroup of scales and translations through careful application of subsampling and upsampling layers and the use of aforementioned scale-equivariant layers.

Morphological adjunctions represented by matrices in max-plus algebra for signal and image processing

no code implementations28 Jul 2022 Samy Blusseau, Santiago Velasco-Forero, Jesus Angulo, Isabelle Bloch

In discrete signal and image processing, many dilations and erosions can be written as the max-plus and min-plus product of a matrix on a vector.

Differential invariants for SE(2)-equivariant networks

1 code implementation27 Jun 2022 Mateus Sangalli, Samy Blusseau, Santiago Velasco-Forero, Jesús Angulo

Symmetry is present in many tasks in computer vision, where the same class of objects can appear transformed, e. g. rotated due to different camera orientations, or scaled due to perspective.

Scale Equivariant Neural Networks with Morphological Scale-Spaces

no code implementations4 May 2021 Mateus Sangalli, Samy Blusseau, Santiago Velasco-Forero, Jesus Angulo

The translation equivariance of convolutions can make convolutional neural networks translation equivariant or invariant.

Max-plus Operators Applied to Filter Selection and Model Pruning in Neural Networks

1 code implementation19 Mar 2019 Yunxiang Zhang, Samy Blusseau, Santiago Velasco-Forero, Isabelle Bloch, Jesus Angulo

Following recent advances in morphological neural networks, we propose to study in more depth how Max-plus operators can be exploited to define morphological units and how they behave when incorporated in layers of conventional neural networks.

Psychophysics, Gestalts and Games

no code implementations25 May 2018 José Lezama, Samy Blusseau, Jean-Michel Morel, Gregory Randall, Rafael Grompone von Gioi

Using a computational quantitative version of the non-accidentalness principle, we raise the possibility that the psychophysical and the (older) gestaltist setups, both applicable on dot or Gabor patterns, find a useful complement in a Turing test.
