Generalized Shortest Path-based Superpixels for 3D Spherical Image Segmentation
Rémi Giraud, Rodrigo Borba Pinheiro, Yannick Berthoumieu
The growing use of wide angle image capture devices and the need for fast and accurate image analysis in computer visions have enforced the need for dedicated under-representation…
Handling Multiple Hypotheses in Coarse-to-Fine Dense Image Matching
Matthieu Vilain, Rémi Giraud, Yannick Berthoumieu +1
Dense image matching aims to find a correspondent for every pixel of a source image in a partially overlapping target image. State-of-the-art methods typically rely on a coarse-to-…
SPDGAN: A Generative Adversarial Network based on SPD Manifold Learning for Automatic Image Colorization
Youssef Mourchid, Marc Donias, Yannick Berthoumieu +1
This paper addresses the automatic colorization problem, which converts a gray-scale image to a colorized one. Recent deep-learning approaches can colorize automatically grayscale…
Patch-based image Super Resolution using generalized Gaussian mixture model
Dang-Phuong-Lan Nguyen, Jean-François Aujol, Yannick Berthoumieu
Single Image Super Resolution (SISR) methods aim to recover the clean images in high resolution from low resolution observations.A family of patch-based approaches have received co…
Riemannian information gradient methods for the parameter estimation of ECD: Some applications in image processing
Jialun Zhou, Salem Said, Yannick Berthoumieu
Elliptically-contoured distributions (ECD) play a significant role, in computer vision, image processing, radar, and biomedical signal processing. Maximum likelihood. estimation (M…
PCA Reduced Gaussian Mixture Models with Applications in Superresolution
Johannes Hertrich, Dang Phoung Lan Nguyen, Jean-Fancois Aujol +4
Despite the rapid development of computational hardware, the treatment of large and high dimensional data sets is still a challenging problem. This paper provides a twofold contrib…
