"Image Mining"

Schedule 2023-2024: November-December / Wednesdays morning

Objectives, Pre-requisites and Content
Images and Videos represent a major source of information today.
There is an increasing demand for automated methods to organize huge collections of image data, and to interpret images and videos by computer.

The Image  Mining  course  deals  with  the  problem  of  increasing  the semantics of visual data by: (1) reducing its information to relevant data, and (2) indexing it relatively to a model and/or to a previous knowledge, in order to facilitate its retrieval and interpretation by a machine.

The  course  does  not  assume  previous  knowledge  in  Image  Processing,  but basics  in  signal  processing,  information  theory  and  pattern  recognition  are useful.

After presenting the different mathematical models for images, the feature extraction and description methods are described.
One third of the course is dedicated to Classification and Machine Learning methods : Clustering, Dimension Reduction, Bayesian learning, Neural Networks.
The video analysis problem is addressed through the fundamental task of Visual Object Tracking.
An important case study is extensively presented: the mining and retrieval of Remote Sensing images.
Finally, some emerging trends and challenges linked to subjective image mining are presented in the lecture on Computational Aesthetics.
