A linear relationship (or linear association) is a statistical term used to describe the directly proportional relationship between a variable and a constant.

A new approach to represent the local change of material properties or source terms due to their nonlinear characteristics is presented here. The material function is given in terms of simple basis ...

Ill-posed linear inverse problems appear in many image processing applications, such as deblurring, super-resolution and compressed sensing. Many restoration strategies involve minimizing a cost ...
