Medical image registration using information theory measures Ivan Vnucko vnucko@sccg.sk In my presentation I will shortly introduce medical image registration, its main applications and a widely used nine criteria classification of existing methods. Next part is an overview of a general registration procedure and its three main components. I will address one of them - the similarity measure with focus on information theory based measures, like entropy and mutual information. In the last part I will mention challenges for this field and describe some interesting recent methods.
