I2PRef: Image-Driven Point Completion with Iterative Refinement
Azhar Hussian, Marina Ritthaler, André Kaup +1
We present an image-conditioned point cloud completion approach that treats images as the primary geometric source rather than a secondary guide. To this end, we introduce an Image…

Improved Motion Plane Adaptive 360-Degree Video Compression Using Affine Motion Models
Marina Ritthaler, Andy Regensky, André Kaup
Efficient compression of 360-degree video content requires the application of advanced motion models for interframe prediction. The Motion Plane Adaptive (MPA) motion model project…
