Sampling Based Scene-Space Video Processing

no code implementations5 Feb 2021 Felix Klose, Oliver Wang, Jean-Charles Bazin, Marcus Magnor, Alexander Sorkine-Hornung

We present a novel, sampling-based framework for processing video that enables high-quality scene-space video effects in the presence of inevitable errors in depth and camera pose estimation.

PhaseNet for Video Frame Interpolation

no code implementations CVPR 2018 Simone Meyer, Abdelaziz Djelouah, Brian McWilliams, Alexander Sorkine-Hornung, Markus Gross, Christopher Schroers

We show that this is superior to the hand-crafted heuristics previously used in phase-based methods and also compares favorably to recent deep learning based approaches for video frame interpolation on challenging datasets.

Efficient Large-scale Approximate Nearest Neighbor Search on the GPU

1 code implementation CVPR 2016 Patrick Wieschollek, Oliver Wang, Alexander Sorkine-Hornung, Hendrik P. A. Lensch

We present a new approach for efficient approximate nearest neighbor (ANN) search in high dimensional spaces, extending the idea of Product Quantization.

Learning Video Object Segmentation from Static Images

2 code implementations CVPR 2017 Anna Khoreva, Federico Perazzi, Rodrigo Benenson, Bernt Schiele, Alexander Sorkine-Hornung

Inspired by recent advances of deep learning in instance segmentation and object tracking, we introduce video object segmentation problem as a concept of guided instance segmentation.

A Benchmark Dataset and Evaluation Methodology for Video Object Segmentation

1 code implementation CVPR 2016 Federico Perazzi, Jordi Pont-Tuset, Brian McWilliams, Luc van Gool, Markus Gross, Alexander Sorkine-Hornung

The dataset, named DAVIS (Densely Annotated VIdeo Segmentation), consists of fifty high quality, Full HD video sequences, spanning multiple occurrences of common video object segmentation challenges such as occlusions, motion-blur and appearance changes.

Phase-Based Frame Interpolation for Video

1 code implementation CVPR 2015 Simone Meyer, Oliver Wang, Henning Zimmer, Max Grosse, Alexander Sorkine-Hornung

Standard approaches to computing interpolated (in-between) frames in a video sequence require accurate pixel correspondences between images e. g. using optical flow.

Scalable Structure From Motion for Densely Sampled Videos

no code implementations CVPR 2015 Benjamin Resch, Hendrik P. A. Lensch, Oliver Wang, Marc Pollefeys, Alexander Sorkine-Hornung

Videos consisting of thousands of high resolution frames are challenging for existing structure from motion (SfM) and simultaneous-localization and mapping (SLAM) techniques.

Megastereo: Constructing High-Resolution Stereo Panoramas

no code implementations CVPR 2013 Christian Richardt, Yael Pritch, Henning Zimmer, Alexander Sorkine-Hornung

As our first contribution, we describe the necessary correction steps and a compact representation for the input images in order to achieve a highly accurate approximation to the required ray space.
