Semi-Synthetic Dataset Augmentation for Application-Specific Gaze Estimation

no code implementations27 Oct 2023 Cedric Leblond-Menard, Gabriel Picard-Krashevski, Sofiane Achiche

Although the number of gaze estimation datasets is growing, the application of appearance-based gaze estimation methods is mostly limited to estimating the point of gaze on a screen.

Improving Convolutional Neural Networks Via Conservative Field Regularisation and Integration

no code implementations11 Mar 2020 Dominique Beaini, Sofiane Achiche, Maxime Raison

Current research in convolutional neural networks (CNN) focuses mainly on changing the architecture of the networks, optimizing the hyper-parameters and improving the gradient descent.

Saliency Enhancement using Gradient Domain Edges Merging

no code implementations11 Feb 2020 Dominique Beaini, Sofiane Achiche, Alexandre Duperre, Maxime Raison

In recent years, there has been a rapid progress in solving the binary problems in computer vision, such as edge detection which finds the boundaries of an image and salient object detection which finds the important object in an image.

Deep Green Function Convolution for Improving Saliency in Convolutional Neural Networks

no code implementations22 Aug 2019 Dominique Beaini, Sofiane Achiche, Alexandre Duperré, Maxime Raison

The objective of this paper is to show that saliency convolutional neural networks (CNN) can be improved by using a Green's function convolution (GFC) to extrapolate edges features into salient regions.

Novel Convolution Kernels for Computer Vision and Shape Analysis based on Electromagnetism

no code implementations20 Jun 2018 Dominique Beaini, Sofiane Achiche, Yann-Seing Law-Kam Cio, Maxime Raison

The objective of this paper is to present a novel convolution kernels, based on principles of electromagnetic potentials and fields, for a general use in computer vision and to demonstrate its usage for shape and stroke analysis.

Computing the Spatial Probability of Inclusion inside Partial Contours for Computer Vision Applications

no code implementations4 Jun 2018 Dominique Beaini, Sofiane Achiche, Fabrice Nonez, Maxime Raison

Hence, it becomes possible to generate a continuous space of probability based only on the edge information, thus bridging the gap between the edge-based methods and the region-based methods.
