The student will acquire knowledge about audiovisual signal processing techniques for both audio and video, and will gain a general understanding of how digital audiovisual content signals should be processed. Additionally, the student will be equipped with the ability to stay updated on developments in science and technology, especially in this field, which is closely linked to a dynamic environment such as telecommunications in general and processing techniques in particular.

The course content is developed in both theoretical and practical parts as follows:

Theoretical Content (Lessons):

Lesson 1: Fundamentals of digital imaging. Perception, relationships between pixels, image geometry.

Lesson 2: 2D signal processing. 2D signal convolution. Neighborhood processing: masks.

Seminar 1: Introduction to programming tools for image processing.

Seminar 2: Wavelet transform.

Seminar 3: Audio editing applications. Autotune.

The development of large group and small group lectures will be focused on promoting quality teaching by giving priority to activities that foster inclusive and equitable learning (SDG-4).

Lectures in large group

 The methodology to be followed in the large group will be a mixture of introductory activities, master classes and the presentation of theory and general examples. In addition to theoretical contents of the subject, the ability to look for information and interpretation of data and handle complex concepts within telecommunications will be developed and enhanced to make judgments that imply reflection on ethical and social issues.

 The student must follow the teacher's presentation with the material available for this purpose, whether they are notes or a slide presentation, which must be completed with their own notes and with the subsequent review of the basic and/or recommended bibliography.

 Attendance, as well as active, respectful and responsible participation, either to raise doubts or to respond to the teacher's requirements or questions, will be evaluated positively in its corresponding factor.

 The student's autonomous work should focus on reviewing the concepts and theoretical aspects taught in class, carrying out exercises, as well as studying them with the material provided by the teacher, student notes and bibliography.

Small group classes

 They will consist of laboratory practices, theoretical/practical seminars in the laboratory or in the classroom where the application of theory to practice and the resolution of problems and exercises are shown.

 The student's work will focus on the development of the learning tasks assigned by the teacher, which culminate in the achievement of the objectives set for each session.

Attendance, as well as active, respectful and responsible participation, either to raise doubts or to respond to the teacher's requirements or questions, will be evaluated positively in its corresponding factor.

 Regarding the autonomous work, it will focus on the preparation of the documentation to be delivered for each practice, as well as on completing the work started in the laboratory and that could not be finished in the corresponding session. Special emphasis will be placed on the need for their own continuous training and to undertake this activity independently throughout their professional life, as well as on the ability to keep up to date with developments in science and technology.

 In addition, communication skills for information, ideas, problems and solutions in the field of engineering and society in general will be developed through task or oral presentations.

 Regarding the organization of work, collaboration and teamwork will be encouraged.

Collective tutorials

  The collective tutorials will be used in the resolution of doubts, monitoring and supervision of the work and exercises, as well as in the attendance and participation in the different seminars planned in the subject, as well as talks, conferences, workshops and/or conferences, designated by the teacher, in order to complete and update the training and obtain general, transversal and/or specific competences defined for this activity, such as the value of continuous training, entrepreneurship or the review of technological innovations in the matter.

 The attendance, as well as the active, respectful and responsible participation, in the aforementioned activities, will be evaluated according to the provisions of the evaluation system of this guide.

Students with special educational needs should contact the Student Attention Service (Servicio de Atención y Ayudas al Estudiante) in order to receive the appropriate academic support

1        Assessment System (detailed description)

1.1       Global Assessment

The Global Assessment modality will be carried out according to the outcomes of the activities described in the section "Methodology and activities", in addition to those described in the section "Detailed description of the Global Assessment" that will be weighted by considering the aspects and percentages detailed in the above table.

The Global assessment modality consists of two parts:

• The work assessment during the term, according to the tasks defined for this purpose.
• The completion of a FINAL EXAM on the day set for the exam during the evaluation period.

The distribution of the weights for each assessable aspect of the two aforementioned parts, and according to the activities described in the table above, is as follows:

Table 1. Weighting of the Global Assessment.

Grades obtained in an aspect during the teaching term in the GLOBAL assessment will be maintained until the end of the academic year.

Final Exam: At the end of the term, on the day set for the course within the exam period, there will be a final exam of the theoretical part and exercises of the course (aspects S2 and S3), in which students must demonstrate that they have acquired the competences and learning outcomes established for these aspects. The weight of this exam in the final grade will be 30% of the total, as reflected in the table "Weighting of the Global Assessment", with 15% corresponding to aspect S2 and the other 15% to aspect S3. The specific conditions, as well as the material and/or documentation that may be used in the final exam will be established by the lecturer.

Final Assessment

In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in the overall results considering all the assessed aspects, provided that they have obtained a grade equal to or higher than 4.0 in the final exam and in the laboratory/computer practical part (S4).

Students will have the option of resigning the GLOBAL evaluation, and it will not be possible to return to it once the resignation has been made.

1.2       Final Exam

In the FINAL EXAM modality, an exam will be held on the day set for the course within the exam period, which will cover all the course contents, ensuring that students have acquired the competences and learning outcomes established for the course. The two parts of this written exam are weighed as follows:

- Part 1: Attendance and participation, theoretical concepts and completion of study cases or exercises assignments (S1, S2, and S3): 70%.

- Part 2: Laboratory/ computer practical work (S4): 30%.

The specific conditions, as well as the material and/or documentation that may be used in the Final Exam will be established by the lecturer.

In order to pass the course, students must obtain a grade equal to or higher than 5.0 out of 10 in each of the two parts.

Students who have passed the S4 aspect (laboratory/computer practical work) of the course, through GLOBAL ASSESMENT, with a grade equal to or higher than 5.0 out of 10, will not have to take Part 2 corresponding to this aspect in the exam. The same grade obtained in the GLOBAL ASSESTMENT will be assigned to this part.

The parts passed at each exam attempt will be maintained until the end of the academic year.

Teaching methodology and learning activities

Schedule

The schedule can vary mainly due to the change from multi-modal scenario to the online one.

Evaluation system

There are no changes in the evaluation format (weights of each section) or in what is specified in the detailed evaluation.

Since the evaluation of the subject is continuous, there will only be an exam in the event that the student opts for the Single Test Evaluation, which is summarized in the following tables:

Ordinary call

Extraordinary call

Resources

Given that the attendance in the large group lectures and in the classes in practice groups is 100%, no exceptional resources are foreseen for them.
