Teaching

Prof. Francesco De Natale

Tecnologie Multimediali


The course provides the basic competences in the field of multimedia signal processing (especially image and video), following the typical processing chain that starts from the signal acquisition and its numerical representation, and continues with the image filtering, transformation, description and characterization. Moreover, the basic principles of image coding are defined, introducing the main techniques for image compression and the relevant international standards. For each topic, the course reviews some of the most significant methodologies, analysing the theoretical background, the algorithmic implementation, and the performances.

Signal, Image and Video


The course provides the basic competences in the field of digital signal processing, with special attention to images and video sequences. Starting from the fundamentals of 1D signal analysis and processing, analog and numerical, in time and frequency domains, we then extend the concepts to the multi-dimensional case of signals in space. Then, we introduce the more important approaches for image filtering and extraction of image descriptors. These concepts are further extended to deal with motion pictures. Finally, the problem of image compression is introduced, focusing on most known techniques for image and video coding, as well as their standard implementations. The approach of the course is rather practical, with the explanation of theoretical concept followed by their translation into algorithmic terms.

Fondamenti di elaborazione del segnale


The course provides basic knowledge about one-dimensional and multi-dimensional signals, in analog and digital format. The students will learn how to analyse a signal in its original domain, as well as in the frequency domain, using appropriate transformations. It will also be shown how a signal is modified by a processing system, in both continuous and discrete domains, and how to design some simple systems to perform basic operations.

The course is taught in italian.

Multimedia Data Security

Nowadays great facility to access information implies the need to study data protection techniques. The objective of the course is the investigation of some methodologies which guarantee secure access to multimedia data, through various data hiding and digital forensics techniques. The student at the end of the course will know a series of state-of-art methodologies for the active and passive forensics analysis of multimedia data and he/she will know how to apply them to digital images in simple scenarios.

Computer Vision

The course aims to provide the student with an in-depth overview on the methods of analysis and management of multimedia data. Starting from the basics of image and video processing, the course will focus on the problems of motion modeling and detection, motion tracking, and object recognition, both by using monocular and multi-view systems.

Comunicazioni Multimediali

The course provides the basic notions as well as a set of application cases related to the technologies for the acquisition, processing, archiving and transmission of multimedia signals and their use in complex multimedia systems. Every topic is first introduced in the class from a theoretical viewpoint and then experienced in the lab by means of software simulation tools. The first part of the course introduces the basic concepts of digital signal processing (sampling, quantization, numerical transmission, frequency-domain representation, stochastic signals). The following part addresses the characterization of one- and multi-dimensional signals (sound, images, video), with particular reference to the problems related to the acquisition, AD conversion and representation of media objects. Then, the basic techniques of image and video processing are reviewed (filtering, description, analysis). Finally, the problem of multimedia signal representation and coding is presented making reference to the most common standard in the field (ISO and ITU coding families). The last part of the course proposes a set of application scenarios in specific areas of multimedia, also involving companies through dedicated seminars.
