FlexBox is a flexible MATLAB toolbox for finite dimensional convex variational problems in image processing and beyond
Nowadays, many problems in image processing consist of minimizing convex energies. Typically these problems can be written as
where denotes a linear operator and
is a proper, convex and lower-semicontinuous function. This Problem refers to the so-called primal formulation of the minimization problem and
is known as the primal variable we are interested in recovering.
