INTERAZIONE E MULTIMEDIA

General learning objectives in terms of expected learning outcomes.

Knowledge and understanding: The purpose of the course is to acquire knowledge that will enable the student to understand the theoretical and physical mechanisms underlying the human visual system, the formation and processing of digital images, of the improvement of the visual quality of digital images.
Ability to apply knowledge and understanding: the student will acquire the skills needed to acquire, edit, compress, and save a digital image. Particularly a part of the course will be related to the study of the Processing software to apply such theoretical knowledge.
Making judgments: Through examples in the classroom, the student will be put into the condition of understanding whether the solutions offered by him meet a certain degree of quality.
Communication skills: The student will acquire the necessary communication skills and technical language skills in the multimedia field.
Learning Skills: The aim of the course is to provide the student with the necessary theoretical and practical methodologies to deal with and solve new problems that arise during a work activity. To this end, several topics will be addressed in lesson by involving the student in the search for possible solutions to real problems.
