DESCRIPTION:\nDiffusion processes are commonly used in image p
 rocessing. In particular\, complex diffusion model
 s have been successfully applied in medical imagin
 g denosing. The interpretation of a complex diffus
 ion equation as a cross-diffusion system motivates
  the introduction of more general models of this t
 ype and their study in the context of image proces
 sing. In this talk we will discuss the use of line
 ar and nonlinear cross-diffusion systems to perfor
 m image restoration. The use of two scalar fields 
 has the goal of distributing the features of the i
 mage and governing their relations. Special attent
 ion will be given to the well-posedness\, scale-sp
 ace properties and long time behaviour of the mode
 ls. This talk is a report of a recent work in coll
 aboration with Adérito Araújo\, Eduardo Custa and 
 Ángel Durán.\n
