The objective of this course is that the student knows what a digital image is (sampling and quantification) and the basic image processing techniques (point-to-point operations, filtering, segmentation, morphological processing, etc). Additionally, it will deepen in the particular case of medical imaging, emphasizing on visualization techniques and multimodal image analysis and registration. On the other hand, students will not only study the techniques, but will also implement them in the laboratory, solving practical problems.
