Teaching method
Two methods are used:
- Lectures
- Hands-on: intensive use of software for digital image processing by exercises
Evaluation method
The assessment includes:
a) Theoretical exam (60% of the final grade)
b) Practical exam (40% of the final grade)
(According to the FCSH Assessment Standards, the proposed evaluation elements to introduce students in the first class may suffer readjustments, particularly in the percentage of each element).
