Numerical reconstruction for 3D nonlinear SAR imaging via a version of the convexification method
Vo Anh Khoa, Michael Victor Klibanov, William Grayson Powell +1
This work extends the applicability of our recent convexification-based algorithm for constructing images of the dielectric constant of buried or occluded target. We are orientated…
Analysis and simulation of a variational stabilization for the Helmholtz equation with noisy Cauchy data
Vo Anh Khoa, Nguyen Dat Thuc, Ajith Gunaratne
This article considers a Cauchy problem of Helmholtz equations whose solution is well known to be exponentially unstable with respect to the inputs. In the framework of variational…
Initial state reconstruction on graphs
Vo Anh Khoa, Mai Thanh Nhat Truong, Imhotep Hogan +1
The presence of noise is an intrinsic problem in acquisition processes for digital images. One way to enhance images is to combine the forward and backward diffusion equations. How…
