Skills -Are able to use mathematical techniques in colour imaging and demonstrate the use of tools such as spreadsheets and specialist maths applications to solve problems in signal and image processing. -Are able to to explore a range of practical techniques, by developing their own simple processing functions using library facilities and tools such as, e.g., Matlab or Python. -Are able to implement the techniques in the topics studied and compare their performances in certain image processing tasks. -Are able to use relevant and suitable methods when carrying out research and development activities in the area of image processing
General competence -Have the learning skills to continue acquiring new knowledge and skills in a manner that is largely self-directed -Are able to contribute to innovative thinking and innovation processes
Learning methods and activities
- Lab work
Additional information: -The course will be offered both as an ordinary campus course and in a flexible way to off-campus students. Lecture notes, e-lectures and other types of e-learning material will be offered through Blackboard. Communication between the teachers and the students, and among the students, will be facilitated by Blackboard.
The portfolio will include compulsory small assignments and a bigger project and the scope and the deadlines for the assignments and the project are announced during the semester.
If the minimum number of students registered for the course is less than 5, the course may not run during a semester.
Further on evaluation
No re-sit examination of the portfolio.
Forms of assessment:
The portfolio consists of up to 4 smaller assignments and one bigger project and is handed in individually. There is continuous assessment of each of the assignments before the final submission date of the portfolio. The portfolio will provide a pass or not pass of the course.
