[CVPR 2021] NeX: Real-time View Synthesis with Neural Basis Expansion Supasorn Suwajanakorn 2021-03-10 | This is a supplementary video for NeX: Real-time View Synthesis with Neural Basis Expansion by Suttisak Wizadwongsa*, Pakkapon Phongthawee*, Jiraphon Yenphraphai*, Supasorn Suwajanakorn. (* first co-authors)nex-mpi.github.ioAbstractWe present NeX, a new approach to novel view synthesis based on enhancements of multiplane image (MPI) that can reproduce NeXt-level view-dependent effects---in real time. Unlike traditional MPI that uses a set of simple RGBα planes, our technique models view-dependent effects by instead parameterizing each pixel as a linear combination of basis functions learned from a neural network. Moreover, we propose a hybrid implicit-explicit modeling strategy that improves upon fine detail and produces state-of-the-art results. Our method is evaluated on benchmark forward-facing datasets as well as our newly-introduced dataset designed to test the limit of view-dependent modeling with significantly more challenging effects such as rainbow reflections on a CD. Our method achieves the best overall scores across all major metrics on these datasets with more than 1000× faster rendering time than the state of the art.

Discovery of Latent 3D Keypoints via End-to-end Geometric Reasoning (NIPS 2018) Supasorn Suwajanakorn 2018-11-23 | We present KeypointNet, an end-to-end geometric reasoning framework to learn an optimal set of category-specific 3D keypoints, along with their detectors. Given a single image, KeypointNet extracts 3D keypoints that are optimized for a downstream task. We demonstrate this framework on 3D pose estimation by proposing a differentiable objective that seeks the optimal set of keypoints for recovering the relative pose between two views of an object. Our model discovers geometrically and semantically consistent keypoints across viewing angles and instances of an object category. Importantly, we find that our end-to-end framework using no ground-truth keypoint annotations outperforms a fully supervised baseline using the same neural network architecture on the task of pose estimation. The discovered 3D keypoints on the car, chair, and plane categories of ShapeNet are visualized on keypointnet.github.io/.This paper is presented at NIPS 2018 (Oral).
Teaser Synthesizing Obama: Learning Lip Sync from Audio Supasorn Suwajanakorn 2017-07-12 | Synthesizing Obama: Learning Lip Sync from AudioSupasorn Suwajanakorn, Steven M. Seitz, Ira Kemelmacher-ShlizermanSIGGRAPH 2017Full Video: youtube.com/watch?v=9Yq67CjDqvwGiven audio of President Barack Obama, we synthesize a high quality video of him speaking with accurate lip sync, composited into a target video clip. Trained on many hours of his weekly address footage, a recurrent neural network learns the mapping from raw audio features to mouth shapes. Given the mouth shape at each time instant, we synthesize high quality mouth texture, and composite it with proper 3D pose matching to change what he appears to be saying in a target video to match the input audio trackhttp://grail.cs.washington.edu/projects/AudioToObama/

Google Cardboard VR Positional Tracking (outside-in, tethered) Supasorn Suwajanakorn 2016-01-20 | I'm trying to add positional tracking to Cardboard App (Full 6DOF). Proper calibration is needed. Tracking is done on computer and position values are sent through USB to the phone (TCP via ADB).Latency is not superb, but should be better than using phone's camera and phone's processing power.github.com/supasorn/CardboardPositionalHack
George Bush driving crowd Supasorn Suwajanakorn 2015-12-03 | Here textured 3D models are reconstructed for famous people using only 2D photos from the internet and are driven by a video of George W. Bush.This is a result from our paper "What Makes Tom Hanks Look Like Tom Hanks" submitted to International Conference on Computer Vision 2015.Webpage: http://grail.cs.washington.edu/projects/3DPersona/
What Makes Tom Hanks Look Like Tom Hanks Supasorn Suwajanakorn 2015-10-22 | We reconstruct a controllable model of a person from a large photo collection that captures his or her persona, i.e., physical appearance and behavior. The ability to operate on unstructured photo collections enables modeling a huge number of people, including celebrities and other well photographed people without requiring them to be scanned. Moreover, we show the ability to drive or puppeteer the captured person B using any other video of a different person A. In this scenario, B acts out the role of person A, but retains his/her own personality and character. Our system is based on a novel combination of 3D face reconstruction, tracking, alignment, and multi-texture modeling, applied to the puppeteering problem. We demonstrate convincing results on a large variety of celebrities derived from Internet imagery and video.

Illumination-Aware Age Progression Supasorn Suwajanakorn 2014-06-07 | We present an approach that takes a single photograph of a child as input and automatically produces a series of age-progressed outputs between 1 and 80 years of age, accounting for pose, expression, and illumination. Leveraging thousands of photos of children and adults at many ages from the Internet, we first show how to compute average image subspaces that are pixel-to-pixel aligned and model variable lighting. These averages depict a prototype man and woman aging from 0 to 80, under any desired illumination, and capture the differences in shape and texture between ages. Applying these differences to a new photo yields an age progressed result. Contributions include relightable age subspaces, a novel technique for subspace-to-subspace alignment, and the most extensive evaluation of age progression techniques in the literature.Learn more at http://grail.cs.washington.edu/aging/
