Towards strain gauge 2.0: Substituting the electric resistance routinely deposited on polyimide film by the optimal pattern for full‐field strain measurement Open
The checkerboard constitutes the best pattern for full‐field strain measurement because it maximizes image gradient. In the experimental mechanics community, employing this pattern is currently strongly limited because depositing it on the…

Sentinel-2 RGB and NIR bands simulation after fire events using a multi-temporal conditional generative adversarial network Open
In remote sensing applications, optical images are widely used to monitor land changes. However, clouds, haze, or smoke hide the area below and, therefore, limit the use of optical data to favorable weather conditions. Since the SAR signal…

On biases in displacement estimation for image registration, with a focus on photomechanics - Extended version Open
Image registration under small displacements is embodied in many image analysis tasks, such as optical flow estimation, stereoscopic imaging, or in photomechanics. A wide family of methods performs registration through local least-squares …

A Non-Local Dual-Domain Approach to Cartoon and Texture Decomposition Open
This paper addresses the problem of cartoon and texture decomposition. Microtextures being characterized by their power spectrum, we propose to extract cartoon and texture components from the information provided by the power spectrum of i…
