Abstract

In this talk I will give an overview of the exciting and growing field of image processing, by introducing how images and video can be modeled and manipulated mathematically. I will provide examples of the typical problems that are studied in this discipline, and present an array of applications in medicine, astronomy, atmospheric science, security, navigation systems, and others in data science and information technology. Also, I shall present the research problem of image reconstruction under "optical turbulence", i.e. the optical phenomenon caused by light rays being refracted to form distorted images at the observer's location: this typically occurs when looking at objects at a distance in hot climates, or underwater in the presence of temperature gradients (i.e., when the water temperature is not the same at different locations). The results of an imaging recovery algorithm will also be illustrated.
