The aim of this module is to provide students with basic and advanced mathematical methods for a theoretical analysis and practical solutions of problems in image reconstruction and image processing with specific applications in astronomical imaging. To this aim data from the most recent NASA and ESA missions will be at disposal. The first part of the module is dedicated to general notions and main operators for image processing. We will therefore address an image reconstruction problem within the Solar Orbiter (ESA) mission, an image processing problem within the SDO/AIA mission (NASA) and a prediction problem within the SDO/HMI mission (NASA). A computer exercise in MATLAB environment is foreseen for each of the problems addressed.
The course objective is to provide specialized mathematical training on the proper methods of reconstruction and image processing with particular reference to the processing of astronomical images.
The topics addressed in this module, together with the computer exercises, are aimed at the acquisition of knowledge and advanced skills in the field of:
Each topic will be addressed in a self-consistent way
The module includes lectures and three computer exercises. Lectures will be held in person.
Basics of image processing: 1) Digital images: sampling and quantization. 2) Basic operators for image processing. 3) Image formation and image recording: blurring and noise. 4) Point Spread Function. 5) Imaging systems in the frequency domain. Transfer function. 6) Filtering in the frequency domain.
Astronomical image processing:

In accordance with the academic calendar approved by the Consiglio di Corso di Studi.
Three computer exercises will take place for which deadlines will be set. The admission to the final oral exam is subject to the approval of the practical exercises during the semester.
Computer exercises are aimed at testing the practical skills acquired for the solution of the posed problems. They will be evaluated on the basis of the following criteria:
The oral exam is finally aimed at assessing the ability to communicate the knowledge acquired in a clear and competent manner
Students with DSA certification ("specific learning disabilities"), disability or other special educational needs are advised to contact the teacher at the beginning of the course to agree on teaching and examination methods that, in compliance with the teaching objectives, take account of individual learning arrangements and provide appropriate compensatory tools.
