Signal and data processing - 2021

Manipulation of digital images

From enhancement to interpretation


During this course, learners will discover the answers to the following questions:

  • What techniques are used to filter images and improve their representation?
  • How do we go from analysis to computer vision?
  • Can we develop robotic systems with vision?


The course lasts 6 days (36 hours).

In 2 parts of 3 days, it includes many exercises and demonstrations.


The digital image is becoming more and more present and software that accompanies digital devices is increasingly sophisticated.

This course offers a simple approach to the processing of digital images from examples. It introduces some of the basic principles of sampling and filtering and gives an overview of the algorithmic techniques used both in the field of research and in an industrial setting.


Course level: Basic/Advanced

Knowledge of basic math functions (logarithm, exponential, linear combination).

Basic knowledge of statistics (mean, standard deviation, median).

Associate Professor of Applied Physics, Doctor of the University of Orsay - Expert in Image Processing, Information System Project Manager at the CGLLS.
