Linear inverse problems: if ℱ is a linear operator. (1) If ℱ=I, the identity operator, then the linear inverse problem is called denoising. (2) If ℱ is a convolution, that is (20)ℱux=∫Ωk|x−y|2uydy, with k being a smooth function, and | · | being the Euclidean...

We present a new regularization method for the solution of the Fredholm integral equation (FIE) of the first kind, in which we incorporate solutions corresponding to a range of Tikhonov regularizers into the end result. This method identifies solutions within a much larger function space, spanned...
Methods of first-order approximation provide solutions to the inverse scattering problems in order to get the first model using minimum a priori information about the system. To check that model, the scattering problem has to be solved. The resulting theoretical model of the function can be then...
in the case of stationary problem the equation (2) becomes a poisson equation or when the source function v q is equal to zero a laplace equation. broadly speaking, inverse problems may be subdivided into the following categories: inverse conduction, inverse convection, inverse radiation and ...
