At the end of this teaching unit, students will be able
- To model an inverse imaging problem under a mathematically well-posed form via a deterministic or stochastic regularization approach, and to solve it using companion optimization methods.
- To specify & use core techniques for solving basic low-level image & video analysis problems, including restoration, multiscale description, point of interest detection, segmentation, calibration & 3D scene reconstruction, motion analysis & tracking.
- To design & conduct an experimental performance study of an image understanding technique, relying on dedicated software tools such as the industry-standard Matlab(R) platform or the open-source OpenCV library.
- To write a synthetic and reasoned critical analysis of a scientific article dealing with an image understanding or computer vision issue.

Evaluation
The assessment pattern involves 3 components: continuous evaluation via homework on selected topics (”coursework”) (CW), lab assignments (L), and a two-student group written final exam (E). The final grade is a weighted average of individual component grades. The 2nd session consists of a study with an oral defense (O).
-1st session = Weighted Average (CW, L, E)) (S1)
-2nd session = O (S2)
-Final grade = Max (SE1, SE2)
