Blind Motion Deblurring with Pixel-Wise Kernel Estimation via Kernel Prediction Networks

1 code implementation5 Aug 2023 Guillermo Carbajal, Patricia Vitoria, José Lezama, Pablo Musé

Then, a second network trained jointly with the first one, unrolls a non-blind deconvolution method using the motion kernel field estimated by the first network.

Scaling Painting Style Transfer

no code implementations27 Dec 2022 Bruno Galerne, Lara Raad, José Lezama, Jean-Michel Morel

Neural style transfer is a deep learning technique that produces an unprecedentedly rich style transfer from a style image to a content image and is particularly impressive when it comes to transferring style from a painting to an image.

Visual Prompt Tuning for Generative Transfer Learning

1 code implementation CVPR 2023 Kihyuk Sohn, Yuan Hao, José Lezama, Luisa Polania, Huiwen Chang, Han Zhang, Irfan Essa, Lu Jiang

We base our framework on state-of-the-art generative vision transformers that represent an image as a sequence of visual tokens to the autoregressive or non-autoregressive transformers.

Rethinking Motion Deblurring Training: A Segmentation-Based Method for Simulating Non-Uniform Motion Blurred Images

1 code implementation26 Sep 2022 Guillermo Carbajal, Patricia Vitoria, Pablo Musé, José Lezama

Successful training of end-to-end deep networks for real motion deblurring requires datasets of sharp/blurred image pairs that are realistic and diverse enough to achieve generalization to real blurred images.

Improved Masked Image Generation with Token-Critic

1 code implementation9 Sep 2022 José Lezama, Huiwen Chang, Lu Jiang, Irfan Essa

Given a masked-and-reconstructed real image, the Token-Critic model is trained to distinguish which visual tokens belong to the original image and which were sampled by the generative transformer.

Non-uniform Blur Kernel Estimation via Adaptive Basis Decomposition

1 code implementation1 Feb 2021 Guillermo Carbajal, Patricia Vitoria, Mauricio Delbracio, Pablo Musé, José Lezama

In recent years, the removal of motion blur in photographs has seen impressive progress in the hands of deep learning-based methods, trained to map directly from blurry to sharp images.

Detecting Out-Of-Distribution Samples Using Low-Order Deep Features Statistics

no code implementations ICLR 2019 Igor M. Quintanilha, Roberto de M. E. Filho, José Lezama, Mauricio Delbracio, Leonardo O. Nunes

The ability to detect when an input sample was not drawn from the training distribution is an important desirable property of deep neural networks.

Overcoming the Disentanglement vs Reconstruction Trade-off via Jacobian Supervision

1 code implementation ICLR 2019 José Lezama

A major challenge in learning image representations is the disentangling of the factors of variation underlying the image formation.

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.

OLÉ: Orthogonal Low-rank Embedding, A Plug and Play Geometric Loss for Deep Learning

1 code implementation5 Dec 2017 José Lezama, Qiang Qiu, Pablo Musé, Guillermo Sapiro

Deep neural networks trained using a softmax layer at the top and the cross-entropy loss are ubiquitous tools for image classification.
