Hybrid Training of Denoising Networks to Improve the Texture Acutance of Digital Cameras

no code implementations20 Feb 2024 Raphaël Achddou, Yann Gousseau, Saïd Ladjal

In order to evaluate the capacity of a camera to render textures properly, the standard practice, used by classical scoring protocols, is to compute the frequential response to a dead leaves image target, from which is built a texture acutance metric.

A Compact and Semantic Latent Space for Disentangled and Controllable Image Editing

1 code implementation13 Dec 2023 Gwilherm Lesné, Yann Gousseau, Saïd Ladjal, Alasdair Newson

Recent advances in the field of generative models and in particular generative adversarial networks (GANs) have lead to substantial progress for controlled image editing, especially compared with the pre-deep learning era.

An analysis of the transfer learning of convolutional neural networks for artistic images

no code implementations5 Nov 2020 Nicolas Gonthier, Yann Gousseau, Saïd Ladjal

Transfer learning from huge natural image datasets, fine-tuning of deep neural networks and the use of the corresponding pre-trained networks have become de facto the core of art analysis applications.

Improving Interpretability for Computer-aided Diagnosis tools on Whole Slide Imaging with Multiple Instance Learning and Gradient-based Explanations

no code implementations29 Sep 2020 Antoine Pirovano, Hippolyte Heuberger, Sylvain Berlemont, Saïd Ladjal, Isabelle Bloch

We formalize the design of WSI classification architectures and propose a piece-wise interpretability approach, relying on gradient-based methods, feature visualization and multiple instance learning context.

High resolution neural texture synthesis with long range constraints

2 code implementations4 Aug 2020 Nicolas Gonthier, Yann Gousseau, Saïd Ladjal

Experiments show the interest of the multi-scale scheme for high resolution textures and the interest of combining it with additional constraints for regular textures.

PCAAE: Principal Component Analysis Autoencoder for organising the latent space of generative networks

1 code implementation14 Jun 2020 Chi-Hieu Pham, Saïd Ladjal, Alasdair Newson

We hope that this approach will contribute to better understanding of the intrinsic latent spaces of powerful deep generative models.

Processsing Simple Geometric Attributes with Autoencoders

no code implementations15 Apr 2019 Alasdair Newson, Andrés Almansa, Yann Gousseau, Saïd Ladjal

This results in a wide range of practical problems, such as difficulties in training, the tendency to sample images with little or no variability, and generalisation problems.

A PCA-like Autoencoder

1 code implementation2 Apr 2019 Saïd Ladjal, Alasdair Newson, Chi-Hieu Pham

In this paper, we propose an algorithm to create such a network.
