Description
Today, most imaging software pipelines distinguish between (at least)
the steps of (1) data acquisition, (2) volumetric reconstruction and (3)
visualization and analysis. Those parts are usually treated as separate
"modules" with only marginal interaction, e.g., through calibration
parameters. In particular, reconstruction is almost always performed on
a whole volume, and the reconstructed 3D image is often visualized by 2D
slicing or a 3D rendering technique.
We propose a new paradigm where visualization and reconstruction are
integrated in the sense that the reconstruction is focused on the region
of view (ROV), i.e. the region at which a user is currently looking by
means of a visualization tool. For non-iterative methods this means that
points outside the ROV can be ignored altogether since the algorithms
work point-per-point. In iterative schemes, the "outside" part can be
represented with a very coarse discretization, thereby strongly lowering
the required computational cost.
The talk introduces the concepts and shows some early results.
