Traitement d'images : introduction au filtrage

Institut Mines-Télécom

Ce MOOC (Massive Open Online Course) on image processing delves into the interdisciplinary nature of this field, encompassing mathematics, physics, and computer science. From manufacturing lines to medical scanners and satellites, images play a crucial role in extracting ubiquitous information. The course emphasizes the systematic processing of images to overcome acquisition challenges, isolate relevant objects, and conduct analysis. Modules cover essential topics such as pixels, colors, resolution, and quantification, alongside hands-on training in Python programming for image processing operations.

Participants will grasp the rudimentary mathematics and computer science concepts required, empowering them to manipulate algorithms and execute fundamental image processing operations. By the course's conclusion, learners will be adept at loading and observing images, analyzing their quality, enhancing sharpness and contrast, applying blur, and detecting edges. Successful completion of the course warrants a certificate of achievement from Coursera, provided the individual attains a score exceeding 50%.
