X-ray CT Image Reconstruction from Few Projections
To improve the safety (lower dose) and the productivity (faster acquisition) of an X-ray CT system, we want to reconstruct a high quality image from a small number of... -

3D Microscopy Deconvolution using Richardson-Lucy Algorithm with Total Variat...
Confocal laser scanning microscopy is a powerful and increasingly popular technique for 3D imaging of biological specimens. However the acquired images are degraded by... -
Generalized Gradient on Vector Bundle - Application to Image Denoising
We introduce a gradient operator that generalizes the Euclidean and Riemannian gradients. This operator acts on sections of vector bundles and is determined by three... -
On continuous maximum flow image segmentation algorithm
In recent years, with the advance of computing equipment and image acquisition techniques, the sizes, dimensions and content of acquired images have increased... -
