Non-Semantic Evaluation of Image Forensics Tools: Methodology and Database

We propose a new method to evaluate image forensics tools, that characterizes what image cues are being used by each detector. Our method enables effortless creation of an arbitrarily large dataset of carefully tampered images in which controlled…

A Reliable JPEG Quantization Table Estimator

JPEG compression is a commonly used method of lossy compression for digital images. The degree of compression can be adjusted by the choice of a quality factor QF. Each software associates this value to a quantization table, which is a 8 × 8 matrix…

Can Push-forward Generative Models Fit Multimodal Distributions?

Many generative models synthesize data by transforming a standard Gaussian random variable using a deterministic neural network. Among these models are the Variational Autoencoders and the Generative Adversarial Networks. In this work, we call them …

Improving the Pair Selection and the Model Fusion Steps of Satellite Multi-View Stereo Pipelines

Multi-view stereo reconstruction of scenes from satellite images is traditionally performed with a pair-wise stereovision approach: (1) multiple views are grouped into pairs, (2) each pair is processed by two-view stereo methods producing an…

Self-Supervised Push-Frame Super-Resolution With Detail-Preserving Control And Outlier Detection

Self-supervised training enables the application of deeplearning based methods for multi-image super-resolution of satellite imagery. In this work we propose two improvements on the self-supervised Deep-Shift-and-Add (DSA) method introduced by…

AUTOMATIC METHANE PLUME QUANTIFICATION USING SENTINEL-2 TIME SERIES

Methane emissions monitoring is essential to control methane pollution. In this paper, we propose an automatic practical methodology using time series to estimate the quantity of methane in a given plume using a multispectral satellite like Sentinel…
