Image reconstruction from scattered Radon data by weighted positive definite kernel functions [PDF]
We propose a novel kernel-based method for image reconstruction from scattered Radon data. To this end, we employ generalized Hermite–Birkhoff interpolation by positive definite kernel functions. For radial kernels, however, a straightforward application

Automatic Synthesis of Anthropomorphic Pulmonary CT Phantoms. [PDF]
The great density and structural complexity of pulmonary vessels and airways impose limitations on the generation of accurate reference standards, which are critical in training and in the validation of image processing methods for features such as ...
