Emotional Voice Puppetry (2023)
Journal Article
Pan, Y., Zhang, R., Cheng, S., Tan, S., Ding, Y., Mitchell, K., & Yang, X. (2023). Emotional Voice Puppetry. IEEE Transactions on Visualization and Computer Graphics, 29(5), 2527-2535. https://doi.org/10.1109/tvcg.2023.3247101

The paper presents emotional voice puppetry, an audio-based facial animation approach to portray characters with vivid emotional changes. The lips motion and the surrounding facial areas are controlled by the contents of the audio, and the facial dyn... Read More about Emotional Voice Puppetry.

Generating real-time detailed ground visualisations from sparse aerial point clouds (2022)
Presentation / Conference Contribution
Murray, A., Mitchell, S., Bradley, A., Waite, E., Ross, C., Jamrozy, J., & Mitchell, K. (2022, December). Generating real-time detailed ground visualisations from sparse aerial point clouds. Paper presented at CVMP 2022: The 19th ACM SIGGRAPH European Conference on Visual Media Production, London

We present an informed kind of atomic rendering primitive, which forms a local adjacency aware classified particle basis decoupled from texture and topology. Suited to visual synthesis of detailed landscapes inferred from sparse unevenly distributed... Read More about Generating real-time detailed ground visualisations from sparse aerial point clouds.

Dense reconstruction for narrow baseline motion observations (2022)
Patent
Mitchell, K., Dumbgen, F., & Liu, S. (2022). Dense reconstruction for narrow baseline motion observations. USPTO

Techniques for constructing a three-dimensional model of facial geometry are disclosed. A first three-dimensional model of an object is generated, based on a plurality of captured images of the object. A projected three-dimensional model of the objec...

MienCap: Performance-based Facial Animation with Live Mood Dynamics (2022)
Presentation / Conference Contribution
Pan, Y., Zhang, R., Wang, J., Chen, N., Qiu, Y., Ding, Y., & Mitchell, K. (2022, March). MienCap: Performance-based Facial Animation with Live Mood Dynamics. Presented at 2022 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW), Christchurch, New Zealand

Our purpose is to improve performance-based animation which can drive believable 3D stylized characters that are truly perceptual. By combining traditional blendshape animation techniques with machine learning models, we present a real time motion ca...

Real-time feature preserving rendering of visual effects on an image of a face (2022)
Patent
Mitchell, K. J., Cambra, L. C., & Li, Y. (2022). Real-time feature preserving rendering of visual effects on an image of a face

Embodiments provide techniques for rendering augmented reality effects on an image of a user's face in real time. The method generally includes receiving an image of a face of a user. A global facial depth map and a luminance map are generated based... Read More about Real-time feature preserving rendering of visual effects on an image of a face.

Collimated Whole Volume Light Scattering in Homogeneous Finite Media (2022)
Journal Article
Velinov, Z., & Mitchell, K. (2023). Collimated Whole Volume Light Scattering in Homogeneous Finite Media. IEEE Transactions on Visualization and Computer Graphics, 29(7), 3145-3157. https://doi.org/10.1109/TVCG.2021.3135764

Crepuscular rays form when light encounters an optically thick or opaque medium which masks out portions of the visible scene. Real-time applications commonly estimate this phenomena by connecting paths between light sources and the camera after a si...

Systems and Methods for Illuminating Physical Space with Shadows of Virtual Objects (2021)
Patent
Velinov, Z. V., Mitchell, K. J., & Hager, IV, J. G. (2021). Systems and Methods for Illuminating Physical Space with Shadows of Virtual Objects

A system can be used in conjunction with a display configured to display an augmented reality (AR) environment including a virtual object placed in a real environment, the virtual object having a virtual location in the AR environment. The system inc... Read More about Systems and Methods for Illuminating Physical Space with Shadows of Virtual Objects.
