Course Description and Objectives

The miniaturization of sensors and the evolution of computational capabilities has led to the ubiquitous presence of images. However, the increasing demand for image-based content also requires sophisticated post-processing (filtering, restoration etc.), in order to ensure good quality results. At the heart of these post-processings are image models, which allow us to establish powerful and efficient algorithms. Deep learning is the latest addition to a long list of such image models. The aim of this course is to present recent techniques based on deep learning for the quality of images, and to compare them to pre-existing methods. We will explore many applications such as denoising, super-resolution, deblurring, texture synthesis and natural image generation. In each case we will present the strengths and limitations of the different techniques studied. In particular, we will present a critical analysis of the methods and show some of the pitfalls in which they sometimes fall.

Language

The course may be given in English or French depending on the audience’s preferences.

Prerequisites

  • Applied Mathematics (Linear Algebra, Numerical Analysis, Differential Calculus, Fourier Analysis) Programming (Python, Matlab)
  • Basic concepts of image processing, optimization and deep learning are useful but will be introduced in the course.

Validation

  • Individual reports of Practical Work (TPs).
  • Individual project with report and oral defense at the end of the course.

Teaching team

Alasdair Newson (MdC Telecom Paris)

Organization of the course

  • 8 sessions of 3 hours each (course+TP) + 3 review sessions + 1 project presentation session
