DISCOVER is an ERC funded project (starting grant 101076028).
Goal
Our goal is to develop approaches to assist experts in identifying and analyzing patterns. Indeed, while the success of deep learning on visual data is undeniable, applications are often limited to the supervised learning scenario where the algorithm tries to infer a label for a new image based on the annotations made by experts in a reference
dataset. In contrast, we want to take as input images without any annotation, automatically
identify consistent patterns and model their variation and evolution, so that an expert can
more easily analyze them.
The concept we will develop is the one of visual structures. Their key features will be their
interpretability, in terms of correspondences, deformations, or properties of the observed
images, and their ability to incorporate prior knowledge about the data and expert feedback.
It will explore two complementary approaches to formally define and identify visual
structures: one based on analyzing correspondences, the other on learning interpretable
image models.
We will develop visual structures in two domains: historical documents and Earth imagery.
For example, from temporal series of Earth images, we want to identify types of
moving objects, areas with different types of vegetation or constructions, and model the
evolution of their characteristics, which may correspond to changes in their activity or life
cycle. Ultimately, experts will still be needed to select relevant visual structures and perform
analysis, requiring to work closely with them, to design relevant features in our algorithms
and adapted interfaces for interaction.
