Exploring Robust Features for Few-Shot Object Detection in Satellite Imagery

1 code implementation8 Mar 2024 Xavier Bou, Gabriele Facciolo, Rafael Grompone von Gioi, Jean-Michel Morel, Thibaud Ehret

Moreover, we study the performance of both visual and image-text features, namely DINOv2 and CLIP, including two CLIP models specifically tailored for remote sensing applications.

Portraying the Need for Temporal Data in Flood Detection via Sentinel-1

no code implementations6 Mar 2024 Xavier Bou, Thibaud Ehret, Rafael Grompone von Gioi, Jeremy Anger

Identifying flood affected areas in remote sensing data is a critical problem in earth observation to analyze flood impact and drive responses.

Reducing False Alarms in Video Surveillance by Deep Feature Statistical Modeling

no code implementations9 Jul 2023 Xavier Bou, Aitor Artola, Thibaud Ehret, Gabriele Facciolo, Jean-Michel Morel, Rafael Grompone von Gioi

Experimental results reveal that the proposed a-contrario validation is able to largely reduce the number of false alarms at both pixel and object levels.

The whole and the parts: the MDL principle and the a-contrario framework

no code implementations13 Dec 2021 Rafael Grompone von Gioi, Ignacio Ramírez Paulino, Gregory Randall

This work explores the connections between the Minimum Description Length (MDL) principle as developed by Rissanen, and the a-contrario framework for structure detection proposed by Desolneux, Moisan and Morel.

Line Segment Detection

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.

From line segments to more organized Gestalts

no code implementations18 Mar 2016 Boshra Rajaei, Rafael Grompone von Gioi, Jean-Michel Morel

In this paper, we reconsider the early computer vision bottom-up program, according to which higher level features (geometric structures) in an image could be built up recursively from elementary features by simple grouping principles coming from Gestalt theory.

Finding Vanishing Points via Point Alignments in Image Primal and Dual Domains

no code implementations CVPR 2014 Jose Lezama, Rafael Grompone von Gioi, Gregory Randall, Jean-Michel Morel

We present a novel method for automatic vanishing point detection based on primal and dual point alignment detection.
