Recently two publications resulting from research work within the Augmented Vision Group were accepted at the WSCG 2014 conference ( Both publications address image-based 3D reconstruction relying on perspective respectively spherical images.

Correspondence Chaining for Enhanced Dense 3D Reconstruction
The paper proposes and evaluates a new algorithm to fuse existing dense two-view 3D reconstruction algorithms to a multi-view reconstruction, where each 3D point is estimated from multiple images. This leads to an enhanced precision and reduced redundancy of the reconstructed model.

Consistent Pose Uncertainty Estimation for Spherical Cameras
The paper discusses and evaluates the reliability of first order uncertainty propagation results in context of spherical Structure from Motion, concluding that they are not valid without restrictions, but depend on the choice of the objective function.

The “International Conference in Central Europe on Computer Graphics, Visualization and Computer Vision” (WSCG) takes place for the 22nd time and will be held from June 2nd to June 5th in Pilzen (Czech Republic).
