The main task of digital image processing is to process and analyze image-like data. Data from any source can be understood as an image if it can be represented in a matrix form. Most often we deal with images of 2 or 3 spatial dimensions, but time (e.g. in video sequences) and spectral dimensions (e.g. in aerial remote sensing) can also be handled. Among others, image processing deals with image restoration (the compensation for degradation), image segmentation (the delineation of objects depicted in the image), image registration (determining the spatial correspondence between images acquired at different time and/or space), image fusion (forming a new image by combining the information from multiple images), calculating object properties and describing the objects and/or the scene depicted in the image. Image processing is applied in an increasing number of areas in life, such as in medical image diagnosis systems, industrial manufacturing and quality control, security systems, from autonomous robots to smartphones with cameras. In this lecture the audience shall get a taste of these topics and challenges through selected projects from the half century history of image processing at the University of Szeged.
