OBJECTIVES Similarly to other Master's elective courses, the student will acquire a greater specialization in different areas of Telecommunications technologies. Particularly, this course covers the following Signal Processing skills: - Mathematical basis of signal processing. - General knowledge on potential speech/audio/image/video processing applications. - Basic subsystems of speech/audio/image/video processing applications. - Use of speech/audio/image/video processing software. - Handling of basic processing tools. - Solving speech/audio/image/video processing problems by using several basic tools.

The goal of this subject is to provide the student with an introduction to recent signal processing techniques with application to speech, audio, image and video. To that end, a Project-Based Learning Approach is followed. The emphasis is put on lab exercises, so that the student can be assessed according to her work on a mini project. 1.- Course presentation 2.- Introduction to Deep Learning 2.1. Neural Networks 2.2.

DNNs for Video Processing. 6.- Case Studies and Applications of Speech, Audio, Image and Video Processing

Two teaching activities are proposed: theoretical classes with examples and lab exercises. THEORETICAL CLASSES WITH EXAMPLES (2 ECTS) The theoretical class will be given in the blackboard, with slides or by any other means to illustrate the concepts of the lectures. In these classes the explanation will be completed with examples (AF1, MD1). In these sessions the student will acquire the basic concepts of the course. It is important to highlight that these classes require the initiative and the personal and group involvement of the students (there will be concepts that the students should develop by themselves) (AF3, MD3). LABORATORY EXERCISES (1 ECTS) Some basic selected concepts learnt during the course are applied in the lab. The students should participate actively in the exercise implementation. There will be two types of lab exercises: - Guided lab exercises: getting used to speech, audio, image and video processing using Python (AF2, AF4, MD4). - Final Project: image or speech/audio processing problem to be solved in groups (AF6, AF7, MD2, MD5).
