Props Alive: A Framework for Augmented Reality Stop Motion Animation
Presentation / Conference Contribution
Casas, L., Kosek, M., & Mitchell, K. (2017, March). Props Alive: A Framework for Augmented Reality Stop Motion Animation. Presented at 2017 IEEE 10th Workshop on Software Engineering and Architectures for Realtime Interactive Systems (SEARIS), Los Angeles, CA, USA

Stop motion animation evolved in the early days of cinema with the aim to create an illusion of movement with static puppets posed manually each frame. Current stop motion movies introduced 3D printing processes in order to acquire animations more ac... Read More about Props Alive: A Framework for Augmented Reality Stop Motion Animation.

Adaptive polynomial rendering
Presentation / Conference Contribution
Moon, B., McDonagh, S., Mitchell, K., & Gross, M. (2016, July). Adaptive polynomial rendering. Presented at ACM SIGGRAPH 2016, Anaheim, California, US

In this paper, we propose a new adaptive rendering method to improve the performance of Monte Carlo ray tracing, by reducing noise contained in rendered images while preserving high-frequency edges. Our method locally approximates an image with polyn... Read More about Adaptive polynomial rendering.

Real-time variable rigidity texture mapping
Presentation / Conference Contribution
Koniaris, C., Mitchell, K., & Cosker, D. (2015, November). Real-time variable rigidity texture mapping. Presented at Proceedings of the 12th European Conference on Visual Media Production - CVMP '15

Parameterisation of models is typically generated for a single pose, the rest pose. When a model deforms, its parameterisation characteristics change, leading to distortions in the appearance of texture-mapped mesostructure. Such distortions are unde...

Carpet unrolling for character control on uneven terrain
Presentation / Conference Contribution
Miller, M., Holden, D., Al-Ashqar, R., Dubach, C., Mitchell, K., & Komura, T. (2015, November). Carpet unrolling for character control on uneven terrain. Presented at MIG '15 Proceedings of the 8th ACM SIGGRAPH Conference on Motion in Games

We propose a type of relationship descriptor based on carpet unrolling that computes the joint positions of a character based on the sum of relative vectors originating from a local coordinate system embedded on the surface of a carpet. Given a terra... Read More about Carpet unrolling for character control on uneven terrain.

Latency aware foveated rendering in unreal engine 4
Presentation / Conference Contribution
Swafford, N. T., Cosker, D., & Mitchell, K. (2015, November). Latency aware foveated rendering in unreal engine 4. Presented at Proceedings of the 12th European Conference on Visual Media Production - CVMP '15

We contribute a foveated rendering implementation in Unreal Engine 4 (UE4) and a straight-forward metric to allow calculation of rendered foveal region sizes to compensate for overall system latency and maintain perceptual losslessness. Our system de... Read More about Latency aware foveated rendering in unreal engine 4.

Augmented creativity: bridging the real and virtual worlds to enhance creative play
Presentation / Conference Contribution
Zünd, F., Ryffel, M., Magnenat, S., Marra, A., Nitti, M., Kapadia, M., Noris, G., Mitchell, K., Gross, M., & Sumner, R. W. (2015, November). Augmented creativity: bridging the real and virtual worlds to enhance creative play. Presented at SIGGRAPH ASIA 2015 Mobile Graphics and Interactive Applications on - SA '15

Augmented Reality (AR) holds unique and promising potential to bridge between real-world activities and digital experiences, allowing users to engage their imagination and boost their creativity. We propose the concept of Augmented Creativity as empl... Read More about Augmented creativity: bridging the real and virtual worlds to enhance creative play.

IRIDiuM+: deep media storytelling with non-linear light field video
Presentation / Conference Contribution
Kosek, M., Koniaris, B., Sinclair, D., Markova, D., Rothnie, F., Smoot, L., & Mitchell, K. (2017, July). IRIDiuM+: deep media storytelling with non-linear light field video. Presented at ACM SIGGRAPH 2017 VR Village on - SIGGRAPH '17, Los Angeles, California

We present immersive storytelling in VR enhanced with non-linear
sequenced sound, touch and light. Our Deep Media (Rose 2012) aim
is to allow for guests to physically enter rendered movies with
novel non-linear storytelling capability. With the ab... Read More about IRIDiuM+: deep media storytelling with non-linear light field video.

Online view sampling for estimating depth from light fields
Presentation / Conference Contribution
Kim, C., Subr, K., Mitchell, K., Sorkine-Hornung, A., & Gross, M. (2015, September). Online view sampling for estimating depth from light fields. Presented at 2015 IEEE International Conference on Image Processing (ICIP)

Geometric information such as depth obtained from light fields
finds more applications recently. Where and how to sample
images to populate a light field is an important problem to
maximize the usability of information gathered for depth reconstru... Read More about Online view sampling for estimating depth from light fields.

Real-time rendering with compressed animated light fields.
Presentation / Conference Contribution
Koniaris, B., Kosek, M., Sinclair, D., & Mitchell, K. (2017, May). Real-time rendering with compressed animated light fields. Presented at 43rd Graphics Interface Conference

We propose an end-to-end solution for presenting movie quality animated graphics to the user while still allowing the sense of presence afforded by free viewpoint head motion. By transforming offline rendered movie content into a novel immersive repr... Read More about Real-time rendering with compressed animated light fields..

Light Field Synthesis Using Inexpensive Surveillance Camera Systems
Presentation / Conference Contribution
Dumbgen, F., Schroers, C., & Mitchell, K. (2019, September). Light Field Synthesis Using Inexpensive Surveillance Camera Systems. Presented at 2019 IEEE International Conference on Image Processing (ICIP), Taipei, Taiwan

We present a light field synthesis technique that achieves accurate reconstruction given a low-cost, wide-baseline camera rig. Our system integrates optical flow with methods for rectification, disparity estimation, and feature extraction, which we t...
